Note 1. When exchanging data through ports 1 and 2, it is necessary to confirm the
status of the data transfer (communications status) in the words allocated
to the RS-232C Unit in the Master Unit’s Input Area.
2. It is possible to operate ports 1 and 2 independently, but the RS-232C Unit
can process only one explicit message at a time. Even if you are going ex-
ecute a send command or receive command for the other port, confirm that
the previous explicit message processing has been completed before ex-
ecuting the next explicit message.

Explicit DeviceNet messages sent from the Master Unit can be used to control
the parameters of the RS-232C Unit’s ports 1 and 2 and to control the flow of
data.
The RS-232C Unit processes the commands received from the Master Unit
and returns responses.
