Communication
port
The CN1 interface of the MD600S and
MD600A models supports connection with
the commissioning software through
Modbus RTU, but does not support
connection with the operating panel.
The CN1 interface supports communication
with the PLC.

The CN2 terminal of the MD600S and MD600A
models supports connection with the
operating panel through the Modbus RTU
and supports connection with the operating
panel.
The CN2 interface of the MD600A models
also supports CANopen/CANlink
communication.

It is connected to 24V by default. When DI1 to
DI5 are driven by external signals, connect
OP to COM or the external 24 V power supply,
and disconnect OP from the internal 24V
terminal by setting the S4 DIP switch to ON.
