3-1-4 Communication Units and I/O Units
The Communication Unit interfaces the I/O Units to the PROFIBUS-DP
Network.
•
It automatically recognizes the configuration of the I/O Units when the I/O Unit
interface is initialised.
•
It notifies the connection status (status information) of the I/O Units to the
PROFIBUS-DP Master Unit.
•
It provides a dip-switches to set the stations address of the MULTIPOINT I/O
TERMINAL as a PROFIBUS-DP Slave.
There are various I/O Units that can be connected to the I/O Unit interface.
•
I/O Units are connected to the Communication Unit using an I/O Unit
Connecting Cable (included with the I/O Unit, a 1-m I/O Unit Connecting Cable
(GCN1-100) is also available).
•
No address or baud rate settings are required on the I/O Units.
•
The connection order of I/O Units is flexible.
