Introduction This document details how to install and commission your Modblok digital solution.

Modblok allows for simple interfacing of Hamilton ARC style probes into a DeltaV control system. All

probe parameters are brought into the DeltaV system while utilizing few resources (DST and serial

dataset).

Modblok acts as a Modbus RTU data collector for dual Hamilton probes. As of this document version, pH

and DO probes are supported, but in the near future, the full portfolio of Hamilton probes will be

supported.

Although all Hamilton ARC probes support Modbus RTU, the data mapping is not easily managed by

Emerson DeltaV Modbus RTU master implementation. The reason why is the Hamilton Modbus map is

fragmented, and each register set mixes data of different type. DeltaV Modbus implementation requires

a Modbus operation to act on a contiguous set of registers with a consistent type and direction. For

example, a multiple register read requires that all registers be contiguous, of the same type (Integer or

Floating Point), and direction (read or write). When a slave device has data that is fragmented, this can

require many small register sets (data sets) and associated operations resulting in excessive resource

usage (both DST and serial port hardware in the case of DeltaV) and segment performance issues.

Modblok implements two features that alleviate any resource usage issues while still allowing full access

to the entire probe data set. These features are:

1) Data aggregation – Modblok reads data continuously from both probes, and arranges the data

in a manner compatible with DeltaV requirements

2) Data multiplexing – Modblok does not demand a DeltaV register per probe parameter. Instead,

lower priority data that is not used for control is slowly periodically collected in parts as opposed

to each module or Modbus segment cycle.

The end result of the above is full access to all probe parameters with total 2 DST consumption.

Modblok has been designed foremost with ease of use, as such configuration of Modblok and associated

probes is largely plug and play.

In addition to supporting Hamilton ARC style probes, the Modblok is available with a pressure sensor

(Pendotech) input option.

Modblok Multiplexing Discussion Every Hamilton probe possesses a myriad of operating parameters. The total parameter count for all

the probe types is approximately 200 to 300. This huge number of parameters is not practical to

continuously read each module scan, nor is this operationally beneficial. Most of these parameters are

either static, only change on a probe write, or very slowly change.

Bearing in mind the nature of the probe data, Modblok characterizes each register access into one of

the following categories:

Modblok User Manual

4

1) Static – These values are read once as part of initialization (refer to probe scan section) and are

not continuously read. They would only be read on communication loss. Examples of these

type of values are probe model number, description, etc. Once in use, these parameters will not

change.

2) On-Write – These values are read once as part of initialization, and are only re-read as part of a

write operation. This sequence is automatic, and is implemented as part of the write logic. An

example of this type of value would be a user string, or other writeable parameter.

3) Continuous-Slow – These values are continuously read, however at a rate on order of a minute.

An example of this type of parameter would be Optical Spot health. This is a continuously

decreasing value, however the value changes perhaps hourly, and there would be no benefit to

read any faster.

4) Non-multiplexed – These values are used for control. They are not included in the multiplexing

strategy, and are read as fast as possible. The 5 non-multiplexed values are:

a) Main Process Variable (termed PMC1 – Primary Measurement Channel 1 by Hamilton). This

would be DO/pH value of the probe.

b) Main Process Variable status (PMC1)

c) Temperature Process Variable (termed PMC6 – Primary Measurement Channel 6 by

Hamilton). This is temperature, regardless of the probe type.

d) Temperature Process Variable status (PMC6)

e) If ordered with the pressure sensor option, pressure measurement.

By implementing the above, all probe registers are able to brought into the DeltaV system without

excessive DST usage.

Modblok Components The following parts are required for a working Modblok system:

1. Modblok Digital Device – Box with DCS and Probe ports

2. DCS cable – This cable plugs into DCS port (Cable M12 5 pin male end) to customer serial card

(Flying lead end)

3. Probe cable – This cable plugs into probe port (cable M12 5 pin male end) to Hamilton probe (VP

connector). To use both probe ports, 2 identical cables are required. The cable is universal for

all supported Hamilton probes.

4. Magnetic commissioning key – This is simply a magnet used to initiate Modblok device

commissioning. Please refer to the Modblok commissioning section for details.

DeltaV System Setup

DeltaV system setup consists of installing a module faceplate, a probe spreadsheet, and importing the

composite templates into the DeltaV database.

Modblok User Manual

5

Graphics For each operator station, Pro and ProPlus computer, copy the Modblk_fp.grf file to the DeltaV

faceplate picture folder. This is typically either:

C:\DeltaV\DVData\Graphics-iFix\PIC\Faceplates

OR

D:\DeltaV\DVData\Graphics-iFix\PIC\Faceplates

Hamilton Probe Spreadsheet (csv file) For each operator station, Pro and ProPlus computer, create a probes folder inside the DeltaV picture

folder. Similar to the faceplate graphics, this new folder should be either:

C:\DeltaV\DVData\Graphics-iFix\PIC\probes

OR

D:\DeltaV\DVData\Graphics-iFix\PIC\probes

In the above folder, copy the RegisterMap5.csv file. Do this for all the above operator, Pro and ProPlus

computers.

Composite Templates From the ProPlus computer, import the MBLK_2_V5.fhx file by:

1) In DeltaV explorer, select File Menu -> Import -> Standard DeltaV Format

2) In file open dialog, select MBLK_2_V5.fhx

After doing the above steps, the import should be successful. If there are errors, please contact us for

assistance.

DeltaV System Configuration DeltaV system configuration consists of adding a serial device (the Modblok device), configuring the

device register set, creating a Modblok device DeltaV control module, and assigning the control module

external references to device registers.

Serial Card/Port configuration In general, a Modblok device will co-exist with other devices on the RS-485 bus. In DeltaV explorer,

expand the appropriate serial card and port. Under this port, add a new device, choosing an unused

address. Note that port settings such as baud rate, number of stop bits, and parity do not need to be

changed. The Modblok device can communicate with any valid Modbus RTU setting.

For the particular serial card, configure the port if required.

NOTE: Modblok comes default with the below settings. It is recommended that if possible to

configure the DeltaV serial device with these settings. Otherwise, any Modbus RTU compatible

settings may be selected, however this will necessitate a Modblok commissioning procedure to be

performed.

Modblok User Manual

Default settings are:

Baud Rate: 38,400

Parity: Even

Data Bits: 8

Stop bits: 1

Address: 16

Right click on the serial card, and select properties. If default settings are selected, these will look like:

Modblok Installation

Port and LED Indicator Overview – Front Face

As the above shows, A single Red LED indicates device power (24V DC)

The Modblok device has 3 separate serial ports. The first is for the DeltaV DCS, and is the left most port.

The other ports to the right of the DeltaV DCS port are Probe 1 and Probe 2 respectively.

Each port (DCS, Probe 1, and Probe 2) has a green communications LED. This LED is lit when the

associated port has good communications. When DCS and box are communicating, the green LED above

the DCS port is lit. Likewise, when the box and Probe is communicating, the green LED above that port is

lit.

During normal operation with 2 probes, all LEDs are lit.

Modblok User Manual

19

Port Overview – Right Face

On the right had side, if ordered with pressure sensor option, the port for the pressure sensor is

available. Currently, the Modblok with pressure measurement supports Pendotech single use pressure

sensors.

Master (DCS) Port Cable The Master (DCS) port cable connects the Modblok device to the DCS system. This cable has a Male 5

pin M12 connector on one end, and flying leads on the other end. The male 5 pin M12 connector plugs

into the Modblok left hand port. Plug this connector to left hand DCS port, and tighten threaded fitting

via knurled portion of the connector.

The flying lead end is for connection to customer RS-485 bus. The following table shows wire colors and

functions for customer termination:

Blue/White 24V DC Gnd

Blue 24V DC Positive

Brown RS-485 (A)

Brown/White RS-485 (B)

How the above wires are terminated depends on customer control system layout.

Probe Port Cables The probe port cable connects the Hamilton probe to the Modblok device. The cable has a male 5 pin

M12 connector on one end, and a VP connector on the other.

Plug the M12 connector into the appropriate probe port (Probe 1 or Probe 2 port), and tighten threaded

fitting via knurled portion of the connector.

Plug your probe into the VP connector side of the cable, and tighten threaded fitting via knurled portion

of the connector.

Modblok User Manual

20

Please note that each probe port is “Agnostic” with respect to the probe type. Provided the probe is a

supported Hamilton probe, the Modblok device will automatically be able to determine the type and

read the appropriate parameters. Also, please note that the probe cable is “universal” for all supported

probe types.

Pressure Port Cables If the pressure sensor option is ordered, a pressure port cable is required. This has a M12 connector on

one side which plugs into the Modblok device, and a Pendotech 4 pin connector on the other end which

the single use sensor is plugged into.

Graphic Overview - Faceplate The Modblok graphics consist of a DeltaV control Module faceplate, and embedded VBA forms

associated with this faceplate graphic.

Below is a screenshot of the faceplate graphic.

The faceplate graphic gives an overall view of the Modblok device and connected probes. It if from here

that all probe parameters can be viewed, written, and where probe calibration is performed.

The included faceplate graphic function is targeted for probe installation, setup, diagnostics, and

maintenance (e.g. calibration) than it is for operations. For operations, user should continue using their

standard graphics and control modules. The Meiry provided modules and graphics should be considered

as interfaces to the probe, but not as operational graphics/controllers. In this way, the same look and

feel are maintained.

Modblok Device Status

Modblok User Manual

21

The Modblok Device status is shown in the top left-hand corner of the graphic. The actual status value is

a bitfield, and is not intuitively obvious what the value means. To the right, there is a communication

indicator with value either “Good” or “Bad”. This is the key indicator, where Good indicates that the

Modblok device is communicating with the DCS.

When the Modblok device is initially connected to the DeltaV control system serial bus, it is likely that

the communication settings are different between the Modblok device and the DeltaV serial bus. In this

case, the Modblok status indicator will show Bad. It is the act of commissioning the Modblok device

which sets the Modblok device communication settings to match those configured.

Modblok Commission When the Modblok device DCS port communication settings do not match those as configured in the

DeltaV DCS, the device cannot communicate and the status will be Bad as shown above. When the

Modblok device is commissioned, these communication settings are set to match those configured in

the DeltaV DCS.

NOTE: This step is only necessary if the current Modblok communication parameters do not match

those configured in the DeltaV. The default communication parameters are as follows:

Baud Rate: 38,400

Parity: Even

Data Bits: 8

Stop bits: 1

Address: 16

Only when communications status is bad will the Commission Box button be visible as below

To prevent the Modblok device from inadvertently entering the commissioning state, the commissioning

procedure is a three-step process:

1) The Modblok device is unlocked via the included magnetic key. Place the magnetic key on the

top center of the box.

2) Press the Commission Box button on the graphic

After step 2 is completed, the DeltaV module will send a “signature” which the Modblok device uses to

self configure.

3) Remove the DCS cable to power down the box. Wait 5 seconds, then reinstall the DCS cable.

During commissioning, a 5-minute timer is started. If this timer expires, the commissioning process has

failed, and will be aborted.

On successful commissioning, the status will be good and the commission box button will be invisible.

The valid Modbus RTU configuration is stored in non-volatile memory such that on power loss, re-

commissioning will not be required.

Modblok User Manual

22

Probe Status and Value

The current probe value and communication status of the probe is shown in the top middle of the

faceplate graphic.

Probe Selection

The combo-box on the upper left-hand side of the faceplate allows selection of probe. Valid choices are

Probe 1 and Probe 2, corresponding to the probe plugged into port 1 and port 2.

Probe Commissioning

Modblok will attempt to communicate to both probes connected to ports 1 and 2. If the port

communication settings (baud rate, parity, number of stop bits) is not as configured in the probe, then

communication will be bad, and the probe type will be None (unknown).

Probe Commissioning is the act of configuring the Modblok probe port communication settings to match

the connected probe, and determining the probe type.

The probe commissioning state diagram is below.

When a probe is initially plugged in or powered up, if the probe communication settings do not match

the Modblok port, the state will remain “No Communication”. As previously stated, this is indicated by

probe status of Bad, and Probe Type of None.

To commission the probe, press the Commission Probe Button

Once the button is pressed, Modblok will iterate through all the possible probe port settings, and when

the correct setting is found for probe communication, Modblok will store these settings in non-volatile

Modblok User Manual

23

memory and continue using these. At this point, the commissioning state is “Good Communication”.

This state is characterized by probe communication with the Modblok device, but the probe type is

unknown. This is shown on the graphic as Probe Status as Good, and Probe Type is None.

At this point, Modblok will query the probe and automatically determine the probe type. This can take

up to 2 minutes. When the appropriate registers are read, the probe type is known, and the

commissioning state is “Discovered”. At this point, the Probe Type will display the connected Hamilton

Probe type.

When a probe is unplugged or powered down, the commissioning state is “No Communication”. If the

communication settings of the Modblok port match those of the probe, the commissioning state

automatically becomes “Good Communication” and subsequently “Discovered”

Probe Scan On probe initial installation or communication loss a probe scan is required. The probe scan takes

approximately 15 minutes, and does a full read of all probe parameters. The main process variables

(PMC1 and PMC6) as well as their status are available, but to browse parameters, write probe

parameters, or to calibrate the probe it is necessary to read all parameters.

Where a probe scan is required, a red Probe Scan Required is visible. Please note, that the details must

be shown to have visibility for probe scan status.

To initiate a probe scan, click the Scan Probe button. A form will open. Click the Start button.

Modblok User Manual

24

As the scan progresses, the progress is shown in the form:

The scan will take approximately 15 minutes.

At the end of the scan, a message box will show, and will state that the scan was successful, or that

certain number of parameters could not be read.

If some items could not be read:

Modblok User Manual

25

If some parameters could not be read, please re-initiate the probe scan.

To cancel the scan, click the Cancel button. The current read completes, and therefore it can take 5

seconds to respond.

Probe Write Register Set To write one of the probe writeable registers, click the Write button

A form will be visible. Navigation to the parameter set is via the group combo-box selector on the left-

hand side, and register set combo-box to the right.

Once a register set has been selected, a set of fields corresponding to the parameters and their types is

visible. User either types or selects via combo-box the values and clicks the OK button. It takes

approximately 10 seconds to write a value. During this time, the “WRITE IN PROGRESS” text will be

visible.

For example, to change the operator level of the probe:

The above shows that the Group is Logon, and register set (starting at Modbus address 4288) is

Operator Level. The user selects Specialist from the drop down box, and enters in the probe password.

Unless the probe password has been changed, the default password is integer value 16021966. To write

the selected value(s), press the OK button. A message “WRITE IN PROGRESS” will be visible.

Modblok User Manual

Module Integration The following DeltaV module parameters are typically used in downstream control strategies (XXX

denotes module name):

Probe 1 main parameter (pH or DO): XXX/PROBESET/PROBE1/PMC1_PV

Probe 1 secondary parameter (Temperature): XXX/PROBESET/PROBE1/PMC6_PV

Probe 2 main parameter (pH or DO): XXX/PROBESET/PROBE2/PMC1_PV

Probe 2 secondary parameter (Temperature): XXX/PROBESET/PROBE2/PMC6_PV

Pressure measurement: XXX/PROBESET/PRESS

For each of the above process variable, logic will set status (.ST) field based on measurement quality.

Probe Calibration

Calibration Overview Probe calibration is typically performed at the start of any production run, and can optionally be

performed while in service. The calibration itself is meant to bring the probe measurement back into

published specifications.

Standard Calibration A standard calibration is typically performed before a production run. This generally entails performing

a 2 point calibration for reusable probes, and entry of calibrations constants for single use probes.

Product Calibration A Product calibration is optionally performed during a production run. An initial measurement is taken

by the probe, and at the same time, a sample is analyzed in the lab. When the lab value is known, this is

entered by the operator, and the probe automatically adjusts calibration constants to current product

conditions.
