9-3
9
(1) Switch SW5
Specify the communication function.
- "1" when selecting remote I/O function.
(2) Switch SW3
Specify an operation mode (0 to 2) for use when an error occurs using SW3-3 and SW3-4.
- In all modes, when the slave station recovers from an error, communication is restored automatically.
- Select mode 1 and 2 for the following cases:
a) Not directly related to an important sequence operation, such as when using the remote I/O
merely to provide output to a monitor board.
b) Stop only the remote slave station, such as in a trial operation
Since a remote I/O error is a type of system I/O error, normally you should select mode 0.
- Switches 3-1, 3-2, 3-5, and 3-6 are not used. (The settings are fixed when delivered.
- See page 4-3.)
(3) Switch SW4
Specify the number of slave stations that will be connected (1 to 4).
(4) Switch LT
Specify whether JW-32CUM1 is a termination station (ON) or an intermediate station (OFF) in the
remote I/O communication circuit. - See page 4-1.
[2] Switch settings
Set switches SW5 (communication function), SW3 (operation mode), SW4 (number of slave stations),
and LT (termination resistance) on the JW-32CUM1.
