DESCRIPTIONS

RUN Contact (LED) Behaviors
Input units (00, A1, A2, G1 and P1)
: The LED turns ON with the network configured; OFF in an abnormality; the network is reconfigured after an abnormality.
Output units (C1, C2, C3, C4, M1 and U1)
: The LED turns ON when data from the paired input unit is received normally, with the network configured; OFF when the data is lost; turns also OFF in an abnormality in the network.
I/O-mixed units (E1, E2, R1 and S1)
: Functions of both input and output units are used.
[CAUTION]
When the network is reconfigured e.g. by noise interference, the RUN LED and output for all units on the network turn briefly OFF until they are turned ON after the reconfiguration is complete.
