Section 11-2
Fault Action
A communications error occurs when communications with the Master
Unit are interrupted.
Idle Action
Idle action is the status that results when an idle output specification is re-
ceived from the Master Unit. An idle output is specified when a CPU Unit
monitoring error occurs in a CS/CJ-series Master Unit.

11-2-3 Network Power Voltage Monitor
Description
The Network Power Voltage Monitor function stores the present value, mini-
mum value, and maximum value of the network power voltage in the Slave
Unit memory. If a monitor voltage is set using the CX-Integrator, the monitor
voltage is stored in the Slave Unit memory. (The default is 14 V.) If the voltage
drops below the monitor voltage, a flag in a status area in the Slave Unit will
turn ON to notify the Master Unit. The notification details can be read using
the CX-Integrator or using explicit messages.
Note (1) The minimum communications power voltage for the CompoNet network
itself is 14 V, so if the network power voltage drops below 14 V, it may not
be possible to read a measurement value using the CX-Integrator.
(2) The maximum and minimum values of the network power voltage are
cleared when the network power is turned OFF.
Settings Using the CX-Integrator
1,2,3... 1. Turn ON the power to the CompoNet Slave Unit.
