Figure 10.3 – I3N100/14004-SEHF CAN Port Wiring
CAN communications are provided via three
connectors on the CAN connector: CAN_LOW (CL),
CAN_HIGH (CH), and V- (C).
If iCAN expansion I/O is to be used, a 24VDC power
source will be required on the iCAN bus in order to
power the expansion I/O modules.
