Appendix IV CANopen Expansion Card (EC-CM-C1)
IV.1 General
Communication card EC-CM-P1 is defined as CANOPEN slave communication
card and used to connect EM500 inverter to CANOPEN network.
Main features:

It supports Node Guard protocol and master can use this function to view device
status.

It supports Heartbeat protocol, with which slave reports present status to master
regularly.

It supports NMT network management protocol, with which inverter receives the
message for inverter status control by master and changes its own communication
status.

SDO only supports accelerated sending mechanism, up to 4 bytes in transmission,
and can be used to read and write device parameters.

PDO supports 4 groups and user may select 1 group randomly; this can be used to
transmit the data required for real time transmission in the transmission
communication process, up to 4 bytes for each frame.
IV.2 Installation Instructions

Install CANopen expansion card into the expansion slot EC-B (make sure that it
is installed and buckled properly).

Disassemble or install CANopen expansion card only after inverter is powered
off.
