External Load Short-circuit Detection
1,2,3...
The method used to check information from the DeviceNet Configurator (Ver.
2.20 or later) is described here.
1. Turn ON the power to the DRT2-series Smart Slave.
2. Click the right mouse button over the icon of the DRT2-series Smart Slave
3. Select the IN Tab from the Monitor Device Window. When a short-circuit is
DRT2-OD@@C(-1), DRT2-MD16S(-1), and DRT2-OD16SLH(-1)
The load current of the Output Unit can be monitored, and an external load
short-circuit can be detected when the current drops below a set value per
contact (or common). When an external load short-circuit is detected, the out-
put is turned OFF to prevent damage to the Unit's output circuit. With Environ-
ment-resistive Terminals, output contacts that have not short-circuited will
operate normally. The LED indicators on the Slave Unit can be used to check
which contact has been detected as having an external load short-circuit.
(Refer to the information below.) Either the Configurator or explicit messages
can be used to read which contact has the external load short-circuit. When
an external load short-circuit is detected, the Short-circuited Flag in the Status
Area is turned ON. (The Configurator or explicit messages can be used to
read the status of the Short-circuited Flag.) The Unit will recover when the
cause of the short-circuit is removed by automatic or manual recovery. Set the
to be set in the Network Configuration Window, and select Monitor.
detected, the short-circuit status will be displayed in the Short-circuit field.
