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:
