Introduction
All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with CANbus CANopen Slave. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.
Supported series: CAN Bus 2.0a / CAN Bus 2.0B device

| W | SDO_16bit | HHHHHH | 0~FFFFFF | |
| W | SDO_32bit | HHHHHH | 0~FFFFFF |
CAN Settings
NOTE: NMT START COMMAND will be sent when this BIT is set to ON, and will return to OFF after sending. The [Send NMT START command] in CAN Settings must be checked, otherwise it is invalid. When using NMT START command and Request mode, the [Update time] must be set to 300ms or more.
Wiring Diagram
NOTE: The serial port pin assignments may vary between HMI models.
CANBus
| HMI | Direction | PLC |
|---|---|---|
| Pin assignments | CAN Bus Device | |
| CAN- | ↔ (bidirectional) | CAN- |
| CAN+ | ↔ (bidirectional) | CAN+ |
| GND | ↔ (bidirectional) | GND |
To minimize signal reflection on the CAN bus network, termination resistors should be installed at both ends of the network, as shown in the following figure.
