Table 148
COM Setup
There are five parameters associated with communications:
• ComProtocol which may be set to COMLI or MODBUS RTU.
• Identity which may be set to any number within the range 1 to 247
• RS-485BaudRate which may be set to a maximum value of 38,400 baud.
• RS-232BaudRate which may be set to a maximum value of 38,400 baud
• WriteEnable which may be set to On or Off.
Communication modes can be switched both from the front and via the
ComputerModeEnable input (described above). The Front Switch (via the
Operator Option List) and ComputerModeEnable have equal priorities.
If WriteEnable is set to Off, a supervisory system can not write to the controller´s
registers when the Communication Mode is Local.
