Modbus TCP Configuration on I/O Transfer Menu:
Enable Modbus TCP Server
(Slave) Check this box to enable the onboard Modbus TCP Server. All Modbus TCP
connections to the module IP Address and specified Modbus Server Device ID
will be routed to the onboard I/O registers.
Modbus Server Device ID Specify the Modbus Device ID for the onboard Modbus TCP Server. Allowed
values are 0 to 255.
Enable Modbus TCP Client
(Master) Check this box to enable the onboard 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 Comm’s
Fail When Enabled the value in any onboard 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 onboard I/O registers will be reset if a valid
Modbus transaction directed at that register has not completed.
Enable Modbus Statistics Enables the Modbus Diagnostic registers as shown in Section Error!
Reference source not found. “Internal Diagnostic Modbus Registers”
Disabling this option will free up the registers and also slightly increase
processing resources.
Log background Noise RSSI & BGND on Rx messages are made available in the diagnostic registers
(See
Error! Reference source not found. “Internal Diagnostic Modbus
Registers” for details. For a Hex value of 5F5D the 5D byte = RSSI and the 5F
byte = BGND (Convert value from hex to dec and add a “-“e.g. 5F = -95dB).
Enabling this option removes the RSSI byte from these registers and so only
the Background Noise value is made available.
Modbus TCP Client Mappings on I/O Transfer Menu:
Local Register Enter the starting onboard 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 register 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.
Comm Fail Register
Enter the onboard 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
