11-6-2 Load Short-circuit Detection (Output)
Description
This function monitors the load current for the output section and detects an
load short-circuit if the current per contact (or common) exceeds a specific
value. When a load short-circuit is detected, all Unit outputs are turned OFF to
prevent damage to the Unit's output circuits.
The I/O power for the Unit turns OFF if a short-circuit is detected for even just
one of the contacts being used.
The Slave Unit's SHT0 or SHT1 indicators can be used to check whether a
load short-circuit has been detected. When a load short-circuit is detected, a
flag in a status area in the Slave Unit turns ON to notify the Master Unit. The
notification details can be read using the CX-Integrator or using explicit mes-
sages.
When the cause of the short-circuit is removed, the Slave Unit is automatically
reset, and the power output to the connector for which the short-circuit was
detected is turned ON again.
Short-circuit
Outputs are forcibly turned OFF

Short-circuits to the load
can be detected.
