[6] Connecting a programmable controller using the computer link function
Connect a programmable controller to the communication connector (RS232C/RS422) and the input/
output terminals on the IV-S20 main housing.
1
Connect the computer link connector (RS-232C/RS-411) of a programmable controller to the
communication connector (RS232C/RS422: 9-pin D-sub, female) on the IV-S20 main housing.
- See Chapter 14 "Computer Link" for details about the procedure for connecting to specific
manufacturers' controllers.
(The pin arrangement of the communication connector on the IV-S20 main housing is
shown on page 6-16 to 6-17.)
- In the case of RS-232C, the maximum communication cable length depends on the c o m -
munication speed.
