5.4 Connection of Remote I/O Unit
A maximum of two remote I/O units can be connected to the communication terminal. Manufacture the
R211 cable (refer to cable manufacturing drawings for details) and connect it to the connector CR5 on
the rear of the communication terminal as shown below.
Use the enclosed connectors and contacts. If the accessories are insufficient, use the CN211 connector
set (optional, with one end).
The remote I/O unit serial link station No. setting method, etc., are the same as for when connecting to
the control unit. However, the machine control input/output signal assignment addresses will differ.
(Refer to "PLC Interface Manual" for details.)
