Additional Information
•
Unused bits in the CompoBus/S I/O Link Unit’s output words can be used as work bits.
•
Unused bits in input word cannot be used as work bits.
(1) Determining Node Number
•
The CompoBus/S I/O Link Unit is a Slave Unit with 8 input bits and 8 output bits. The
node number setting is made using the DIP switch; the inputs and outputs share the
same node number.
•
The range of possible node number settings is determined by the type of PLC the Mas-
ter Unit is mounted to and the settings on the Master Unit.
For details, refer to the CompoBus/S Operation Manual (Cat. No. W266).
(2) Making DIP Switch Settings
Use the DIP switch to set the CompoBus/S I/O Link Unit’s node number, communications
mode, and the status of output data when a communications error occurs.
Precautions for Correct Use
Precautions for Correct Use
