Module Configuration
This document has only information about the device connection settings and its address syntax.
For further Information, see:
Channels Configuration
No custom settings are required.
On TCP/IP settings, you can optimize communication using the field:
NodeConnections: Defines the maximum number of parallel requests that will be sent to each node (asynchronous communication)
Nodes Configuration
Primary Station
Stations syntax: <IP > ; <Port >
Where :
<IP> = IP address of the slave device in the network
< Port > = TCP port where the slave device is listening (default is 44818)
Example: 192.168.1.101; 44818

Point Address Syntax
The syntax for the ControlLogix communication points is: <File Type><File Number> : <Address>
- File Type: identifies the Operand.
- File Number: number reference for the File Type
- Address: address number in the PLC.
The valid values for File Type are:
