4 Communication Connection
4.1 Networking
This PLC can be connected to other slaves (such as MD520/MD800 AC drives and
SV630N/SV660N servo drives) through the EtherCAT interface or connected to other
modules with EtherCAT. With GE20‑CAN‑485 extension card and CAN bus
communication, an all‑in‑one network can be achieved in MD800. Meanwhile, the
point‑to‑point communication can be realized between the PLC and PC/HMI through
GE20‑232/485 extension card, as shown below.
