Max modules refers to max number of modules can be plugged into the HMI (all slots),
If you are planning to use PLCM03 and PLCM04 (additional serial ports) you will obtain following “COM
- Slot#” association:
• a module plugged in Slot#1 or into Slot#2 will be COM2,
• a module plugged in Slot#3 or into Slot#4 will be COM3.
If you are planning to use two PLCM01 (CAN interface) you will obtain following Slot# association:
• a module plugged in Slot#1 or into Slot#2 will be the CanPort 0,
• a module plugged in Slot#3 or into Slot#4 will be the CanPort 1.
Below you can nd relation between modules and max number of modules that can be used into eX
series 700 panels, based on their Interface Type:
