Bank: It is to modify the channel for communication between Recorder and Observer from Real-
Time Viewer. Four banks are available. In each bank protocol options Disable, Modbus_RS232 and
Modbus_TCP are available for user selection. This Bank is used for Real-Time Viewer only, which is
different from the Bank used for recorder itself on Page 60.
For Ethernet, Recorder uses port no. 502 for communicating with Observer. If you change the port
number in Observer, you cannot establish communication between Observer and Recorder. Port no: 502
is used to establish communication between recorder and Observer software to exchange data on Ethernet
over Modbus_TCP protocol.
