Chapter 4 Diagnostic Properties
The filter is used to avoid premature error messages when a capacitive load is
activated or an inductive load is deactivated, and during other voltage peaks when
a status changes.
When a channel is in the static state (permanently activated or deactivated) the
controller uses a fixed specified duration of 100 ms for filtering the error message.
Voltage Errors at M12 Slots
(Sensor Short-circuit) Pin 1 of every M12 input socket on the module supplies a monitored sensor
voltage V
S
.
When a sensor short-circuit occurs, a voltage error is reported. Both channel
indicators of the M12 input socket light up red, and the relevant error bit for the
sensor short-circuit is set in the diagnostic bytes.
The error message is filtered by the Fault Delay parameter.
Overload of Output Drivers The output drivers of the module with output functions report an error when
they detect an overload. This error is reported by setting the relevant channel
error bits in the diagnostic bytes.
If there is an overload, the status indicator of the active output channel lights up
red. If both output channels of an M12 slot are active during an overload, both
status indicators light up red.
The error message is filtered by the Fault Delay parameter.
Error in Actuator Power
Supply The voltage value at the connections for the power supply of the actuator is
monitored globally and at the module level.
If the actuator power supply U
L
goes outside the voltage range of 18…30V, an
error is reported. The U
L
indicator lights up red, and the actuator undervoltage
bit is set in the module information byte.
When output channels are activated, the voltage error is also displayed by setting
the relevant error bits of the M12 slots.
ATTENTION: If both output channels of an M12 slot are activated when a
channel error occurs, the controller locks both channels, even if only one
channel is affected by the error. If only one channel is activated, the controller
only locks this channel. Locked channels are deactivated and remain in the Off
state if you do not reset them using the controller.
