[5] Slave station settings
On slave modules (such as the JW-21RS), specify a slave station number and the termination resistance
using the switches.
(1) Station number switch
Specify sequential station numbers for each slave station, starting from "1."
- Station numbers for missing stations or duplicate slave station numbers will cause a remote I/O error.
- Do not specify "0" or "5" to "9."
(2) Termination resistance switch
Turn ON this switch for a slave module that is at the end of a link circuit. Slave stations in the middle of
the circuit should have this switch turned OFF.
For details about the slave modules, see the JW-21CM User's Manual (Slave module for remote I/O).
ON Enable termination resistance.
OFF Disable termination resistance.
