1Description

The ProMinent Industrial Communication Driver card (Com Module) provides the Aegis II with the ability to

interface with most industrial communication protocols thus providing the customer with live I/O values.

The Com Module includes:

oTwo 4-20mA outputs, assigned as I/O points Iand J

oOne Modbus RTU (RS-485 serial) Master port for a Modbus Pyxis Fluorometer which will be assigned

point M. Any previous use of Mwill be removed. See section 5.

oModbus RTU (RS-485 serial) Slave communication ports for use with a Modbus RTU network or any

Modbus RTU gateway.

oCan be ordered separately or with a power supply and terminal strip mounted in an enclosure. See

section 9.

Optionally, a dual 4-20mA input driver card can be added to this module. Currently, this is the only driver that can

be added. These inputs are assigned letters Kand Lin the controller program. If K and L were previously in use,

those programs are removed.

The Modbus connection is Read only. This connection will not allow any user to edit or modify any part of the

program. Only live I/O data is available. See a complete list of the controller I/O in section 8.

The Slave port can be directly connected to any Modbus RTU Master. RTU Masters includes various SCADA

systems as well as Gateways which convert the data to other Protocols.

Once the Com Module Slave port is connected to a Master, the second Com Module Slave port can be used to

‘Daisy Chain’ other Modbus RTU Slave devices to the same Master. See Daisy Chain example on page 10.

Note: A Master port can monitor multiple Slave devices. A Slave device must obey one and only one Master.

ProMinent has optional Gateway devices to convert this serial connection to Modbus TCP-IP (Ethernet), BACnet

MS/TP (RS 485-Serial) and BACnet IP (Ethernet). Each gateway can be chosen with or without UL certification.

2Layman’s Glossary of terms

TCP and IP indicate Ethernet type connections. MSTP and RTU indicates a serial connection.

In the chart below, the first gateway has the description “Modbus TCP Slave/Modbus Master”. This describes the

gateway as being a slave to the customers Modbus TCP(Ethernet) and passing through to our driver via the serial

port as a Master to our driver card slave connection. Therefore, in each of these descriptions, ‘Modbus Master’

refers to the serial connection between the Gateway and our communication driver.

3Multiple Protocols

The following chart list Gateways available through ProMinent. A link is provided in the event you need a Gateway

manual.

Other Gateways are available from electronics vendors. These gateway part numbers do not include complete

kits. See section 9.

Any gateway that can convert from the user’s protocol to Modbus RTU can be used with the Com Module.

RTA gateways are UL certified. ADFweb brands are not.

An example of Gateways from RTA is shown below.

Driver

4Com Module Installation

From the factory, the Com Module will be installed in expansion slot 3. This card will not operate in expansion

slots 1 or 2. A plastic screw secures the card in place. The Com module may or may not have an optional driver

card attached. This optional driver is supplied with a plastic support screw as well. See optional driver card below.

Never install nor remove any driver or Com Module with power applied to the controller.

Instructions for installation, operation and maintenance of the 4-20mA input driver are in the controller operation

manuals.

The dual 4-20mA input driver can be installed in any expansion slot, Module 1, Module 2, Module 3 or in the feed

through slot on the communication driver card. See next page.

Com Module installed in expansion slot 3

Page 5of 30

Driver card installed on Com module

When a Com Module is added to expansion slot #3, the dual 4-20mA

outputs acquire the identification letters Iand J. These are the letter

assignments for any card installed in this slot.

If the dual 4-20mA input driver is installed onto the Com Module, it is

represented by the letters Kand L.

The Dual 4-20mA input driver card is the only card that can be added

to the Com Module.

5Pyxis Sensor

The Com card was constructed to accept a Modbus RTU version Pyxis Fluorometer. Connect the sensor as shown

below. This is currently the only input to the Master Modbus RTU terminals.

The fluorometer on input Mcan be monitored, used for control, show diagnostics and be calibrated through the

keypad or via a network connection using the Ethernet port or WiFi.

Consult the Aegis II and Pyxis manuals for programming instructions.

The Modbus RTU slave connections allow other entities to monitor this controller. The users can see the I/O

values but cannot edit them.

6The RTU Slave Connection

Connect up to 120 communication driver card slaves to one master. The master can be the plant Modbus RTU

network or any number of Gateways. Currently, ProMinent has six gateways in stock that provide conversion to 3

protocols; Modbus TCP (Ethernet), BACnet IP (Ethernet) and BACnet MSTP (Serial). These gateways are available

with or without UL approval. The RTA brands are UL approved. The ADFweb brands are not UL approved and are

therefore available at a lesser price. See also section 9 for complete enclosure kits.

Gateway devices require a separate DC power supply. See instructions accompanying the Gateway.

The next few illustrations depict ADFweb brand, non-UL approved gateways which convert the Com Module

Modbus RTU Slave to another Protocol. The connection to the Com card is via the Modbus Master serial port on

the Gateway. The Gateway Slave port connects to the plant network Master. This port can be serial or Ethernet as

you choose.
