Configuration options
This indicates the Unit Id (Unit Identifier) list for which
Modbus TCP/IP server should respond. Modbus
requests with any other Unit Id apart from that config-
ured here would be ignored and not responded by the
Modbus TCP/IP server.
Example: 1,2,3,4,5
Multiple Unit IDs are separated by commas.
This would enable / disable the Modbus TCP Server on
the ethernet port.
0 - Modbus TCP/IP server disabled
1 - Modbus TCP/IP server enabled
The IP address of a CIU 888 TCP/IP host port
The IP port number for the modbus host port (which is

This entity was originally defined for the number of
retries on the FieldPort.
However the software of the CIU has implemented dif-

five, does not answer. This tank will decrease the scan

during a configurable amount of time.
