MP-Bus Addressing (FbMpBusAddressing)


WAGO-I/O-PRO CAA Library Elements Category: Building Automation Name: FbMpBusAddressing Type: Function Function block X Program Name of library: MpBus_02.lib Applicable to: All programmable fieldbus controllers Input parameter: Data type: Comment: bAddress BYTE Slave address

Value range 1 – 8 xSet BOOL An increasing slope on this input starts

the addressing via the input of the serial number.

xGetSerialNo BOOL An increasing slope on this input initiates the reading out of the serial number.

typINSerialNo typSerialNo Serial number of the slave to be addressed. The serial number consists of the following parts:

tMaxLearnTime TIME Maximum duration of the learning mode. Default setting = t#120s

Input/output parameter: Data type: Comment: xLearn BOOL With signal TRUE on this input, the

module waits for the service pin message of a slave.

typMpBus typMpBus Data for command and response telegrams as well as for the execution of the function macro on the MP-bus master module.

Return value: Data type: Comment: xReady BOOL Status of the communication

TRUE = communication complete FALSE = active communication with a slave

bError BYTE Output error code: See table in the appendix

typOUTSerialNo typSerialNo Output of the serial number received


9


Graphical display:


With the function block "FbMpBusAddressing", the connected MP-bus drive is assigned a unique MP-bus address. The addressing can be performed in two different ways:

MP-bus addressing type 1 (semi-automatic addressing by activating the service pin):

The desired MP participant address is entered on the input "bAddress".

Connect the input "xLearn" with signal TRUE so that the module goes into learning mode. Then, on the MP-bus drive, trigger the signal for sending the device ID (see operating instructions for the drives). If the address assignment was successful, the input "xLearn" will be reset by the module.

If within the parameterizable time "tMaxLearnTime" no service pin is activated on one of the connected drives or if communication is interrupted, the learning mode is exited automatically and an error message is output on the output "bError".

MP-bus addressing type 2 (addressing via manual entry of the serial number):

The desired MP-bus address is entered on the input "bAddress".

The serial number of the drive to be addressed is entered on the input "typINSerialNumber" (serial number is on the type plate of the drive).

An increasing slope on the input "xSet" triggers the command for addressing the drive via the specified serial number. If the command is not acknowledged correctly by the slave, an error message is output on the output "bError".

An increasing slope on the input "xGetSerialNo" starts the query command for the serial number. The query is directed to the drive with the address specified on the input "bAddress". The queried serial number is displayed on the output "typOUTSerialNo".

The output signal “xReady“ indicates whether the function block has completed the transmission process or if it is still connected to one of the slaves.

The variable "typMpBus" contains the data structure of the MP-bus telegram and must be connected to the variables with the same name on the function block FbMpBusMaster.

Note: The address assignment is also possible with a BELIMO MFT parameterizing device (hand terminal MFT-H or PC tool MFT-P).


Damper/Linear actuator (FbMpBusDamperAndLinearActuator)

Actuators


WAGO-I/O-PRO CAA Library Elements Category: Building Automation Name: FbMpBusDamperAndLinearActuator Type: Function Function block X Program Name of library: MpBus_02.lib Applicable to: All programmable fieldbus controllers Input parameter: Data type: Comment: xEnable BOOL A TRUE signal on this input starts the

transmission process. tCycleTime TIME Time for cyclical query of the drive

Value range = t#1s - t#60s Default setting = t#5s

bAddress BYTE Slave address value range 1 - 8 rPosition REAL Input control signal

Value range 0 - 100 [%] bSensorType BYTE The parameter value on this input

specifies the sensor type used: 0 = no sensor connected 1 = switch (0/1) 2 = active sensor signal 0 to 32 V 3 = PT 1000, 850 – 1600 Ohm 4 = NI 1000, 850 – 1600 Ohm 5 = NI 1000 L&S, 850 – 1600 Ohm 6 = NTC, 100 – 60000 Ohm

xReset BOOL An increasing slope resets the error message of the MP-bus drive.

xActuatorHunting BOOL Error in regulation behavior:

drive oscillates here and there xSensorError BOOL Error, sensor signal is outside of the value

range. Graphical display:


This module serves to query and control the rotary damper and linear actuator with MP-bus interface from BELIMO (e.g. NM, AM, GM, LF, AF, NV, AV, NVS, AVS).

With an increasing slope on the input "xEnable", the transmission and query process is started on the drive addressed via input "bAddress". If the input signal "xEnable" is permanently connected with the signal TRUE, communication occurs cyclically. The cycle time can be determined via the input parameter "tCycleTime".

The target value for the angle of the damper drives or for the hub of the valve drives is specified by the input value "rPosition" and sent to the drive. The current position of the drive is read out by the function block and made available on the output "rOutPosition".

Since most MP-bus drives support the connection of various sensor types, it must be communicated to the module via the input "bSensorType" which sensor is used.

The sensor value read out is displayed on the output "wSensorValue".

The state of a switch (sensor type 1) is evaluated as follows: 1 : open 0 : closed

For active sensors (0 - 32 V), the measurement value is depicted as follows: "wSensorValue" 0 – 32000 mV.

The following auxiliary functions can be used for temperature sensors: Fu_NI1000 (-25°C – 95°C), Fu_NI1000_LuS (-30°C – 115°C), Fu_NTC5K (-20°C – 145°C) Fu_PT1000 (-35°C – 155°C)

The functions are components of the MpBus_02.lib.

The output signal “xReady“ indicates whether the function block has completed the transmission process or if it is still connected to one of the slaves.



Communication errors with the drive in question are displayed on the output "bError". If the module detects a fault (e.g. range exceeded) of the sensor signal, the output signal "xSensorError" is set to the signal TRUE.

Three possible error states of the actuator are indicated via separate outputs on the function module. This affects the following errors:

(1) Signal TRUE on the output „xControlRangeIncreased“ indicates that the control range of the drive has increased or that the end position has been passed over.

(2) Signal TRUE on the output „xMechanicalOverload“ means that the required target position could not be reached, e.g. due to mechanical overload.

(3) Signal TRUE on the output "xActuatorHunting" indicates that there are regulation oscillations. In this state, the control signal of the drive swings back and forth.

An increasing slope on the input "xReset" resets the error messages.

The variable "typMpBus" contains the data structure of the MP-bus telegram and must be connected to the variables with the same name on the function block FbMpBusMaster.

Note: The deletion of the error message "xActuatorHunting" is only possible in the long run if the internal operating hours counter of the drive is reset. This is the case if the relationship between runtime and total operating time does not exceed a particular value.

Volume flow regulator (FbMpBusVav)


WAGO-I/O-PRO CAA Library Elements Category: Building Automation Name: FbMpBusVav Type: Function Function block X Program Name of library: MpBus_02.lib Applicable to: All programmable fieldbus controllers Input parameter: Data type: Comment: xEnable BOOL A TRUE signal on this input starts the

xSet BOOL An increasing slope triggers the transmission of the parameter values for Vmin and Vmax.

xRead BOOL An increasing slope triggers the reading out of the parameter values.

bSensorType BYTE The parameter value on this input specifies the sensor type used: 0 = no sensor connected 1 = switch (0/1) 2 = active sensor signal 0 to 32 V 3 = PT 1000, 850 – 1600 Ohm 4 = NI 1000, 850 – 1600 Ohm 5 = NI 1000 L&S, 850 – 1600 Ohm 6 = NTC, 100 – 60000 Ohm

This module handles the query and control of the BELIMO VAV regulator (e.g. NMV-D2M).

With an increasing slope on the input "xEnable", the transmission and query process is started on the drive addressed via input "bAddress". If the input signal "xEnable" is permanently connected with the signal TRUE, communication occurs cyclically. The input parameter “tCycleTime“ determines the cycle time.

The target value for the volume quantity is specified via the value of the input "rAirVolume". A limitation of the volume flow quantity is possible via the two input parameters "rMinAirVolume" (Vmin) and "rMaxAirVolume" (Vmax).

The minimum limitation "Vmin" is specified depending on the value of the maximum limitation "Vmax." The value for the maximum limitation is specified depending on the nominal volume flow (Vnom). The nominal volume flow is specified by the box manufacturer.

A signal as increasing slope on the input "xSet" causes the values "rMinAirVolume" and "rMaxAirVolume" to be transmitted to the drive. The reading out of these values from the drive is caused by an increasing slope on the input "xRead". They are available as output variables "rVmin" and "rVmax" on the module.

The current position of the drive "rOutPosition" and the actual value of the volume flow in percent "rOutAirVolume_perc" (with respect to the nominal volume of the volume flow regulator) are read out of the function block and displayed. Another important variable that is read out of the drive regulator is the current volume flow in m³/h "rOutAirVolume_m3_h." This value depends on the nominal volume flow, which is stored in the device as a parameter.

Since most BELIMO drives support the connection of various sensor types, it must be communicated to the module via the input "bSensorType" which sensor is used.


The state of a switch (sensor type 1) is evaluated as follows: 1 : open 0 : closed

For active sensors (0 - 32 V), the measurement value is depicted as follows: "wSensorValue" 0 – 32000 mV.

The following auxiliary functions can be used for temperature sensors: Fu_NI1000 (-25°C – 95°C), Fu_NI1000_LuS (-30°C – 115°C), Fu_NTC5K (-20°C – 145°C) Fu_PT1000 (-35°C – 155°C)

The functions are components of the MpBus_02.lib.



Three possible error states of the actuator are depicted via separate outputs on the function module. This affects the following errors:

(1) Signal TRUE on the output „xControlRangeIncreased“ indicates that the control range of the drive has increased or that the end position has been passed over.

(2) Signal TRUE on the output "xMechanicalOverload" means that the required target position could not be reached, e.g. due to mechanical overload.

(3) Signal TRUE on the output "xActuatorHunting" indicates that there are regulation oscillations. In this state, the control signal of the drive swings back and forth.

The output signal "xReady" indicates whether the function module has completed the transmission process or whether there is an active communication connection to one of the slaves.

Communication errors with the drive in question are displayed on the output "bError". If the module detects a fault (e.g. range exceeded) of the sensor signal, the output signal "xSensorError" is set to the signal TRUE.


It is possible to overcontrol the input target value for the volume flow with the input signals "xManualOpen" and "xManualClose" and to move the drive into the open or closed position using the so-called forced control.

The variable "typMpBus" contains the data structure of the MP-bus telegram and must be connected to the variables with the same name on the function module FbMpBusMaster.

Smoke and fire protection damper (FbMpBusSmokeDamper)


Note: in Switzerland, there are no safety regulations for fire protection dampers. If the MP-bus master module is used in this application outside of Switzerland, it cannot be used so that it is relevant to safety.

WAGO-I/O-PRO CAA Library Elements Category: Building Automation Name: FbMpBusSmokeDamper Type: Function Function block X Program Name of library: MpBus_02.lib Applicable to: All programmable fieldbus controllers Input parameter: Data type: Comment: xEnable BOOL A TRUE signal on this input starts the


Value range = t#1s - t#30s Default setting = t#1s

bAddress BYTE Slave address value range 1 - 8 xOpenDamper BOOL Signal for opening and closing of the fire

protection damper. FALSE = Closed TRUE = Open

xTest BOOL Start of the fire protection test run. xReset BOOL An increasing slope resets the initial error

message. Input/Output parameters: Data type: Comment: typMpBus typMpBus Data for command and response



TRUE = communication complete FALSE = active communication


xOpen BOOL The fire protection damper is open xClose BOOL The fire protection damper is closed xDamperTest BOOL Test run fire protection damper active xControlRangeIncreased BOOL Error message: "control range increased"

The saved control angle was exceeded by more than 10 %.

xMechanicalOverload BOOL Error message "mechanical overload" xErrorDamperTest BOOL Damper error detected during periodic test

of the fire protection damper. xDuctTemperature BOOL Channel interior temperature (72 °C) has

been exceeded.



xSmokeDetectorAlarm BOOL External smoke sensor has triggered alarmxSafetyRelMalfunction BOOL Safety-relevant fault Graphical illustration:


This module handles the query and control of the BELIMO smoke and fire protection drives with spring return (e.g. BF24TL).

With an increasing slope on the input "xEnable", the transmission and query process is started on the drive addressed via input "bAddress". If the input signal "xEnable" is permanently connected with the signal TRUE, communication occurs cyclically. The “tCycleTime“ input parameter determines the cycle time.

The closing or opening of the fire protection damper is controlled via the signal on the input "xOpenDamper". The signal TRUE on the input "xOpenDamper" means that the drive opens the damper using the forced function. Here, the drive moves to the adapted end position or "Forced 100%" (runtime 140 s).

Due to an increasing slope on the input "xTest", the fire protection damper test run is carried out. The test includes the shutdown of the entire angle range from the lower to the upper end stop of the damper. If the damper does not reach the end position within a nominal runtime, the error message "xMechanicalOverload" appears.

Via the output "xDamperTest" there is an indication of whether the fire protectection damper test run is currently active.

The outputs "xOpen" and "xClose" indicate if the drive is in the open or closed position.

The output “xReady“ indicates whether the function block has completed the transmission process or if it is still connected to one of the slaves.

Communication errors with the drive in question are displayed on the output "bError".




19


The drive for the fire protection damper monitors the following error states, which are indicated by the controller:

(1) „xControlRangeIncreased“ means: the drive angle of rotation has been exceeded by more than 10 ° (e.g. in case of frame break). As soon as the stop is in the correct location again, the error message is deleted.

(2) „xMechanicalOverload“ means: the angle of rotation is smaller with respect to the adaptation (e.g. obstacle in the damper or stuck damper). This error also occurs if the mechanical end switch of the drive does not close in the closed position.

(3) „xErrorDamperTest“ means: "damper mobility error." If the damper is in the open position, then every 24 hours the drive moves the damper slowly, that is with spring force and motor brake, 7 s back and then open again using motor force. If the drive achieves less than a 5 °angle change during this time, there is an error message. Note: the damper mobility test is started every 24 hours. The error message is deleted automatically with the next successful test run.

(4) „xDuctTemperature“ means: fault channel interior temperature too high. The channel interior temperature > 72 °C has been exceeded. The thermoelectric trigger mechanism in the channel has been triggered. Only after changing out the channel temperature fuse can this fault be acknowledged.

(5) “xSmokeDetectorAlarm“ means: alarm smoke detector. The fire detector contact of the (optionally) connected smoke detector has opened.

(6) „xSafetyRelMalfunction“ means: safety-relevant fault. An ambient temperature > 72 °C or a motor temperature > 85 °C cause this fault message to be triggered. Here the drive is moved into the "emergency" position. The message can only be reset in the factory by BELIMO.

Note: For safety reasons, a timeout monitoring is implemented in the drives for the fire protection dampers. If the function module sends a forced command to the drive, the bus monitoring in the drive is activated. If now the drive does not receive a command from the function module within 60 seconds, the drive closes. With renewed communication, the target value of the controller applies once again.


Window ventilation system (FbMpBusWindow)


WAGO-I/O-PRO CAA Library Elements Category: Building Automation Name: FbMpBusWindow Type: Function Function block X Program Name of library: MpBus_02.lib Applicable to: All programmable fieldbus controllers Input parameter: Data type: Comment: xEnable BOOL A TRUE signal on this input starts the

xMechanicalOverload BOOL Error message drive blocked xInitialise BOOL Initialization or unlocking triggered. xUnlockPosition BOOL Device in unlock position xElectronicError BOOL Electronic error Graphical display:


This function module serves to control the FLS window ventilation system.

With an increasing slope on the input "xEnable", the transmission and query process is started on the drive addressed via input "bAddress". If the input signal "xEnable" is permanently connected with the signal TRUE, communication occurs cyclically. The “tCycleTime“ input parameter determines the cycle time.

Via the "xManual" input, there is a distinction between automatic mode and forced control. If "xManual" = TRUE, the set value of "bAutomaticMode" is taken into account; otherwise "rPosition." With the forced control via "rPosition," the sensor (rain sensor) is deactivated.

Target values for the forced control: 0...0,9 % closed 1...10.9 % crack opening 11...29.9 % 20 % open 30...49.9 % 40 % open 50...69.9 % 60 % open 70...89.9 % 80 % open 90...100 % 100 % open

Automatic mode: 0: "full automatic" 1: "closed" 2: "ventilate a little" 3: "medium ventilation" 4: "ventilate a lot" 5: "open"



Via the "xExtManualOperation" input, the operation of manual switches or remote controls is enabled.


The output “xReady“ indicates whether the function block has completed the transmission process or if it is still connected to one of the slaves.

Communication errors with the drive in question are displayed on the output "bError".

The current position of the drive is read out by the function block and made available on the output "rOutPosition".

Four possible error states of the FLS are depicted via separate outputs on the function module. This affects the following errors:

(1) Signal TRUE on the output "xMechanicalOverload" means that the required target position could not be reached, e.g. due to blockage of the window.

(2) Signal TRUE on the output "xInitialise" indicates that the initialization or unlocking was triggered.

(3) Signal TRUE on the output "xUnlockPosition" indicates that the FLS is in the unlock position.

(4) Signal TRUE on the output "xElectronicError" means that there is an electronic error and the drive must be reprogrammed or replaced.

Since the PTH sensor supports the connection of different sensor types, it must be communicated to the function module via the input "bSensorType" which sensor is used. 0 = Y input measures voltage (in 0.001 V) 1 = Y input measures resistance (in 0.1 Ohm) 2 = Y input for option switch contact


The output “xReady“ indicates whether the function block has completed the transmission process or if it is still connected to one of the slaves. Communication errors with the drive in question are displayed on the output "bError".

The current temperature "rTemperature". humidity "rHumidity", and differential pressure "rDifferentialPressure" of the PTH combi sensor are displayed on the output.

Five possible error states of the sensor are depicted on the outputs: (1) "xMaintenance" indicates a maintenance message from the sensor. (2) "xSensorError" means that the sensor is defective. (3) "xErrorHumidity" indicates that the temperature/humidity sensor is

defective. (4) "xErrorPressure" indicates that the AD converter of the pressure sensor is

defective. (5) "xErrorY_Input" indicates that the AD converter of the Y input is defective.

Graphical illustration:


This module serves the purpose of communication with the signal transmitter UST-3.


The input "rOutputVoltage" specifies the voltage for the analog output.

Via the inputs "xDigitalOutput1", "xDigitalOutput2", and "xDigitalOutput3" it is possible to control the three relays on the UST-3 device.

Since the UST3 signal transmitter supports different measurement ranges, the measurement range of the analog inputs is defined via the input "bSetMeasurementRange" and for checking it is displayed on the output "bMeasurementRange".

Bit 0 = 0 -> voltage analog channel 1 (0..11 V) Bit 0 = 1 -> voltage analog channel 1 (0..3 V)


Bit 3.2 = 01 -> resistance value range (0..5 kOhm) Bit 3.2 = 00 -> resistance value range (0..20 kOhm) Bit 3.2 = 10 -> resistance value range (0..262 kOhm)


Bit 7 = 0 -> no resistance measurement Bit 7 = 1 -> voltage source for resistance measurement

The output “xReady“ indicates whether the function block has completed the transmission process or if it is still connected to one of the slaves. Communication errors with the drive in question are displayed on the output "bError".

The status or measurement values of the digital and analog inputs are displayed on the outputs "xDigitalInput1", "xDigitalInput2", "xDigitalInput3", "rInputVoltage1", "rInputVoltage2", "rInputVoltage3", and "rResistorValue".
