6 Confirming the link of slave stations
Set the PLC inputs (X000 to X003) to ON or OFF in each slave station, and confirm that the outputs
(Y004 to Y007, Y010 to Y013, Y014 to Y017... Y030 to Y033) turn ON or OFF in each slave station.
→ If unable to establish link, refer to "Chapter 9. Troubleshooting."
