2. Introduction The PR210 signal converter is used for conversion of parallel data from encoders, sensors,

thumbwheel switches or PLC into serial information. One of the major applications refers to

replacement of obsolete control products using parallel data interface against new products

providing serial interface only. With use of the PR210 converter the customer can keep all the

parallel structure and cabling of an existing machine and still use modern controllers with serial

interface. Besides this typical application the converter can also be used for many other

technical solutions.

The PR210 parallel input accepts data with BCD, binary or Gray code.

The input data will be packed into a serial protocol and transmitted to one or several target

units via RS232 / RS485 interface.

Conversion and transmission can be controlled at any time by means of the digital status

output signals.

As required four totally difference field of application can be used.

1. Classic application: manual activation

2. Automatic importing and forwarding of new values

3. Fast encoder

4. Data logging

For more detailed information to these four cases see chapter 5.

3.1. Power Supply (X4) The unit requires a 24 VDC power (range 10 ... 30 VDC) which must be applied to screw

terminal strip X4 (X4/1 = minus, X4/2 = plus). The current consumption is about 20 mA

3.2. Connection of the Parallel Input (X3) Parallel input data must be applied to the SUB-D-25 (male) connector X3 on the bottom side of

the unit. Terminal position 8 of the screw terminal strip X2 allows connecting the metal housing

of the SUB-D connector to any external potential *)

Parallel input signals must match with the following specifications:

Input (each line)

Low = 0 ... 3 VHigh = 10 ... 30 V

I = 1 mAin

Principle of input circuit for parallel data (each line)

Unconnected input lines will always be evaluated as a "LOW" signal. The line current with

HIGH state is quasi constant and independent of the input level, due to internal current control

circuits. (Data lines approx. 1 mA, Read input approx. 6 mA).

3.3. The Serial Interface (X1) RS232 and RS485 interfaces are accessible via the X1 SUB-D-9 connector (female) on the top

side of the unit. It is acceptable to connect both interfaces at a time, but you can communicate

only one at a time (while the other one must be idle). Terminal position 9 of the screw terminal

strip X2 allows connecting the metal housing of the SUB-D connector to any external potential *)

Connecting the RS485 interface (4-wire mode)

Where both, RS232 and RS485 interface are in use, you can communicate by

the one or by the other, but not by both interfaces at the same time.

Where you use the RS232 interface only, please make sure you have only wired

pins 2, 3 and 5 (other pins should remain unconnected). As soon as one of the

unused RS485 lines accidentally gets in touch with a remote potential (e. g. by

a fully wired cable due to internal connections inside your PC), this may jam the

RS232 communication.


3.4. Status Outputs (X2) Four digital status outputs are available on the 9-position terminal strip X2. These outputs are

switching to "+" (PNP) and require a remote switching voltage from 10 to 30 V which must be

applied to terminal 2 (Com+). The switching capacity of the outputs is 350 mA each. All outputs

are permanently short-circuit-proof, however only one of them may be in a continuous short

circuit situation at a time to avoid overheating of the drivers.

The following status signals are available:

Out1: Busy

Operates in parallel to the yellow front LED "Busy" and is

switched ON while a serial communication is in progress in one

or the other direction.

Out2: No Response

Switches ON, if the target unit after data transmission does not

respond by ACK or NAK. *)

The status resets automatically upon start of a new transmission.

Out3: Communication Error

Switches ON when the target unit refuses acceptance of transmit

data and responds with a "NAK" character *)

The status resets automatically upon start of a new transmission.

Out4: Input Error

Switches ON after faulty operation of the parallel input, i.e. upon

overheating of the input circuit caused by out-of-range input

levels etc.

The status resets automatically after the input problem has been

solved.

*) Since, by convention, collective addressing (broadcast) does not allow the target unit to respond, this

kind of addressing will disable the output after missing ACK/NAK characters. While the output is set,

the unit will suppress all commands appended to the data string (no "Activate Data", no "Store EEProm").

3.5. The Front LEDs

The green LED is ON as soon as power is applied to the power supply input.

The yellow LED signals the activity of the serial interface by blinking (communication in

one or the other direction is in progress)


4. Basic DIL Switch Settings Some general settings have to be done on the front side 8-position DIL switch.

Positions 1 and 4 are for factory use only and must otherwise be "OFF" at any time.

There is an adjustable debounce filter for elimination of possible noise and interference on the

parallel data input and the READ input. All signal transitions faster than the filter time will be

suppressed. It is recommended to always use the 3 msec. filter, except for special applications.

OFF = Normal operationON = for factory use only

OFF = After power up: use customers parameter settingsON = After power up: reset parameters to default values

OFF = PC communication via OS32 operator softwareON = Normal operation, send data to target unit

OFF = Normal operationON = for factory use only

The example above shows the typical switch settings for transmission of

parallel input data to a serial target unit.

Please note: DIL switch adjustments become only active after next power up.


5. Applications Depending on the setting of the parameters „Parallel Reading Timer“ and „Serial Timer“ four

different cases are possible.

For the description of the complete protocol for the serial communication see chapter 8.3.

Remote setting of operational parameters via simple BCD thumbwheel switch set

An operator parameter for a controller and/or a drive should be set via an external BCD

thumbwheel switch. The selection of the operating parameter and the selection of the target

unit take place through the three connectors of the target selection.

With the activation of the Read-Pin the parallel input will be imported once.

The imported value will be forwarded via the serial device automatically.

Stable signal conditions must be guaranteed at the connectors of the parallel

input pins. Otherwise a safe selection of the operating parameter (or the

selection of the target unit) cannot be assured.

Overview of the relevant parameters and the READ-Pins:

Parameter Approaching/using

„Parallel Reading Timer“ = 0

„Serial Timer“ = 0

5.2. Automatic sending of a new value A parallel encoder should be monitored via a display. Only a modified value of the encoder

should be forwarded to the display automatically.

Automatic sending of a new value

The parallel input is checked permanently. A stable value is available if the value does not

change within the allowed time of the “Parallel Reading Timer”. This stable input value will be

read in.

After that the new read in will compared with his previous value. If there is a difference the

new read in will forwarded via the serial interface automatically.

If there is no difference the abovementioned forwarding won’t be executed.

The change on the parallel input must not exceed the cut-off frequency of 0.5

kHz. Otherwise no stable value will be detected on the parallel input.

„Serial Timer“ = 0

READ-Pin INACTIVE: is not using

With a constant time period given via parameter „Serial Timer“, the parallel input will read in

once (independent whether this value is stable or not) and this value will be forwarded

immediately via the serial interface.

Stable signal conditions must be guaranteed at the connectors of the parallel

input pins. Otherwise a safe selection of the operating parameter (or the

selection of the target unit) cannot be assured.

The alteration rate of the parallel encoder must not exceed 5 kHz.



„Parallel Reading Timer“ = 0

„Serial Timer“ > 0



5.4. Data-Logging A parallel encoder should be monitored permanently and the value of the encoder should be

also shown at a display unit permanently.

The parallel input will be checked permanently. A stable value is available if the value does not

change within the allowed time of the “Parallel Reading Timer”. This stable input value will be

read in.

The read in value will be forwarded cyclically via the serial interface with a time period given

from the parameter „Serial Timer“.

In contrast to the case “automatic sending of a new value” a check of modifications of the read

in value does not take place.

For this case the serial sending of the command “Data storage in the EEProm memory” are not

possible.

The change on the parallel input must not exceed the cut-off frequency of 0.5

kHz. Otherwise no stable value will be detected on the parallel input.

Overview of the relevant parameters of the READ-Pins:


„Parallel Reading Timer“ > 0

„Serial Timer“ > 0



6. Setup by PC and Operator Software For setting of operational parameters and assignment of serial target addresses a PC with

Operator Software OS32 is used. Connect your PC with the PR210 unit as explained under

chapter 3.3, and then start the OS32 software.

The software allows setting of all parameters and also indicates all relevant actual values of

the PR210 unit (parallel input data, logical state of the select lines, output states etc.)

Where after starting the software the text fields remain empty and the head line says „OFFLINE“

please click to the „Comms“ menu in the top line to adjust the serial settings of your PC to the

signal converter.


6.1. Parameter Range "Selection Settings" The selection lines Sel.0 - Sel.2 of the parallel input connector allow selection of totally

*) The description is given in chapter 5.

**) The description is given in chapter 7.


7. Input Polarity

The input polarity is configured with two parameters.

The polarity of all parallel input data is adjusted via the parameter “Input Polarity”.

The parameter “Input Polarity bit” allows the setting of the polarity for every single bit.

The sequencing of execution is:

1. adjustment of all parallel input data

2. adjustment of every single bit

Example: All bits of the LSD (see picture below) should be inverted.

In contrast to the picture in chapter 3 and for reasons of simplicity the pins of the parallel

inputs are shown in inverse sequence.

The easiest way is to enter for every single bit the value 1.

The result can be calculated to hexadecimal or decimal representation.

The result is shown in the following table:

format value

binary 0000 0000 0000 0000 1111 0000

hexadecimal 00 00 F0

decimal 240

The parameter „Input Polarity Single Bit“ is set to 240 and the parameter „Input Polarity“ is set

to zero.

The settings of the two parameters influence both the target selection (Sel.0,

Sel.1, Sel.2) and the value of the parallel encoder.


8. Data Formats and Data Transmission

8.1. Numeric format on the parallel input

8.1.1. BCD coded input data (Parameter "Format BCD/Hex" = 0)

The following numeric range will be evaluated:

Unsigned data (Parameter "Sign" = 0):

The numeric range is defined from 0 to 99 999

Signed data (Parameter "Sign" = 1)

The numeric range is defined from -79 999 to + 79 999

8.1.2. Binary and hexadecimal data (Parameter "Format BCD/Hex" = 1)

Only the lower 16 bits will be evaluated (pin 16 = least significant bit, pin 11 = most significant bit)

Binary data will be considered as unsigned at any time.

8.2. Serial Data Representation

On the serial site numbers will always be expressed in ASCII format.

Leading zeros will never be transmitted

Positive signs will not be transmitted.

Example with BCD data: when the parallel input reads the BCD data 15724, the ASCII result in

the data field of the serial string will appear as 31 35 37 32 34 (hex)

Example with binary or hex data: when the parallel input reads the binary data

0001 0011 1001 1100 (hex 139C), this is equal to a decimal value of 5020. Accordingly the

ASCII result in the data field of the serial string will appear as 35 30 32 30 (hex)

8.3. Serial Transmission Protocol Subsequent indications use standard addressing. *)

8.3.1. Transmit data

After triggering the "Read" command (remotely or by serial timer) the PR210 converter will

transmit the data according to the following protocol:

EOT AD1 AD2 STX C1 C2 x x x x x x x ETX BCC

EOT = Control character (Hex 04)

AD1 = Device address of target unit, High Byte

AD2 = Device address of target unit, Low Byte

STX = Control character (Hex 02)

C1 = register code of destination, High Byte

C2 = register code of destination, Low Byte

xxxxx = numeric data field (numbers use ASCII format)

ETX = Control character (Hex 03)

BCC = Block check character

*) For details about extended addressing please refer to the special document "SERPRO"


No leading zeros will be transmitted.

The Block-Check-Character (BCC) is generated by the EXCLUSIV-OR function of all

characters from C1 thru ETX

Positive values always appear without a sign. Only negative BCD values appear with

a negative sign on top (ASCII "-" corresponding to 2D (hex) )

8.3.2. Acknowledgement by the target unit (valid for all motrona units)

When the target unit has received the data string correctly, the response will be "ACK"

(Acknowledge, control character 06 hex.) Where an error has been detected during transmission,

the response will be "NAK" (Negative acknowledge, control character 15 hex )

8.3.3. Activation of transmit data (valid for all motrona units)

After the target unit has received and stored new data, they have still to be activated by means

of the special command "Activate Data". Hence, after the target unit has sent back a positive

acknowledge "ACK" to the PR210 converter, the converter must send the "Activate" command

after. This command consists of the data value "1" sent to the register code "67". In an example

with a serial device address of "11" the full activation string is:

ASCII EOT 1 1 STX 6 7 1 ETX BCC

Hex 0 4 3 1 3 1 0 2 3 6 3 7 3 1 0 3 3 3

Address Activation Data

8.3.4. Data storage in the EEProm memory

With all motrona units the data is first transferred to the random access memory (RAM). This

means the data are available and active until to the next power down only. After next power up

the previous data stored in the EEProm will be reloaded.

If the data sent by the PR210 should be stored permanently in the non-volatile EEProm memory,

this may be achieved by setting parameter "Store Value" correspondingly. When set to "0", the

data string and the activation string will be automatically followed by a Store command. This

command consists of the data value "1" sent to the register code "68". In an example with a

serial device address of "11" the full string for EEProm storage is:

ASCII EOT 1 1 STX 6 7 1 ETX BCC

Hex 0 4 3 1 3 1 0 2 3 6 3 8 3 1 0 3 3 0
