Overview
Connection Method 2
Connecting the CN1 of the master to the CN1s of the slaves
(a) Connection between master and PLC
Choose the connection port between MJ1 and MJ2.
The communication settings and connection method are the same as those for 1 : 1 connection.
(b), (c), (d) Connection between master and slave
Use the RS-485 (2-wire system) connection. It is convenient to install the optional terminal converter “TC-D9”. Use
twisted-pair cables of 0.3 mm sq or greater. The maximum length of the wiring is 500 m.
Wiring diagrams
When a TC-D9 is used:
Set the slide switch of “TC-D9” to ON (2-wire system).
* As a measure against noise, connect the frame ground terminal of each V9 series at one side only.
When no TC-D9 is used:
Install jumpers bSD and +RD as well as -SD and -RD.
* As a measure against noise, connect the frame ground terminal of each V9 series at one side only.
