Appendix D: Modbus-TCP Client Configuration Manager 43 (70)
Server Settings
Setting Description
Name While not required, renaming the server makes the configuration easier to comprehend. Note
that it is only possible to use uppercase and lowercase characters, numerals and underscore (_).
Default name is ‘New_Server’, followed by an incremental suffix.
Max length: 32 characters.
Server address The IP address of the server.
Protocol TCP.
Port
Default Modbus-TCP port is 502. If the server requires it, it is possible to change.
Value range: 0 - 65535.
Transactions should be added to the server when the server is configured. It’s only possible to have one
server without specified transactions.
Add Transactions
Transactions represent the data that is read from/written to the servers of the Modbus-TCP
network.
The global configuration limits box keeps track of the number of added transactions, the current
minimum allowed scan time, and the current amount of I/O mapped data as well as total
amount of data (both I/O mapped and not I/O mapped data).
To add transactions, select the server in the server list and click Transactions . This shows a list of
all transactions configured for that server.
Click Add new transaction to add a new default transaction to the list and click Edit .
Click OK when the transaction is configured. All data resulting from configured transactions will
be mapped to the internal memory of the linking device. Read transactions will be mapped to
the input area, and write transactions will be mapped to the output area.
