Coil No. Item R/W Description
*1. When either the control circuit terminal block or the coil is turned on, these settings are ON.
The control circuit terminal block has the priority for the multi-function input terminals.
If the master cannot reset the coil ON status because of communication disconnection, turn the control
circuit terminal block from ON to OFF to turn off the coil.
*2. The communications error is retained until a fault reset is input. (Can be reset during operation.)
