System Configuration and Wiring Diagram
The COM1 of the master S8 unit is connected to the COM1 of the slave S8 units.
(a) Connection from master to PLC
Use the COM2 port.
The communication settings and connection method are the same as those for 1 : 1 connection.
(b), (c), (d) Connection from master to slave
Use the RS-485 (2-wire) connection at the COM1 port. It is convenient to install the optional terminal converter “TC-D9”
when S8 unit is connected. Use twisted-pair cables of 0.3 mm sq or greater. The maximum length of the wiring is 500 m.

•
S8 series with TC-D9
* As a measure against noise, connect the frame ground terminal of each S8 series at one side only.

Terminating Resistance Setting
The terminating resistance should be set on the DIP switch.
*
The terminating resistance of COM1 on S806M10D is always set to ON
.
There is no terminating resistance setting for communications between the master and the PLC. Set terminating resistances
as shown below for connections between S8 units.
