Modbus TCP Configuration:

 

Enable Modbus TCP Server 
(Slave) 

Check this box to enable the on-board Modbus TCP Server.  All 
Modbus TCP connections to the module IP Address and specified 
Modbus Server Device ID will be routed to the on-board I/O registers. 

Modbus Server Device ID 

Specify the Modbus Device ID for the on-board Modbus TCP Server.  
Allowed values are 0 to 255. 

Enable Modbus TCP Client 
(Master) 

Check this box to enable the on-board Modbus TCP Client.  I/O to be 
transferred via the Modbus TCP client is specified with Modbus TCP 
Client Mappings. 

Modbus Client Scan Rate 

Enter the delay (in milliseconds) between execution of consecutive 
Modbus TCP Client Mappings to the same server. 

Reset Registers on Comms 
Fail 

When enabled, the value in any on-board I/O register will be reset to 
zero if a valid Modbus transaction directed to/from the given register has 
not been completed for longer than the Comms Fail Timeout. 

Comms Fail Timeout 

The period of time after which on-board I/O registers will be reset if a 
valid Modbus transaction directed at that register has not completed. 

 

Modbus TCP Client Mappings: 

Local Register 

Enter the starting on-board I/O register number that the specified 
Modbus Master transaction will transfer I/O to/from. 

I/O Count 

Specify the number of consecutive I/O registers to be transferred for the 
specified transaction. 

Function Code 

Specify the Modbus Function Code for the transaction. 

Destination Register 

Enter the starting I/O register number in the destination device that the 
specified Modbus Master transaction will transfer I/O to/from. 

Device ID 

Enter the Modbus Device ID of the destination Modbus device. 

Server IP Address 

Specify the IP Address of the destination Modbus TCP Server for the 
specified transaction. 

Response Timeout 

Enter the timeout (in milliseconds) to wait for a response to the specified 
transaction. 

Comms Fail Register 

Enter the on-board I/O Register number to store the communication 
status of the specified transaction.  The specified register will be set to 0 
if communications is successful, 0xFFFF if there is no connection to the 
specified server, or 0xFFxx, where xx is the Modbus Exception Code.
