7.2 Voltage errors at M12 slots
(sensor short circuit)
7 Diagnostics processing
of the module. The value of this parameter can range from 0 to 255 ms; the
factory setting is 80 ms.
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 – that is, when it is permanently activated
or deactivated – the controller uses a fixed specified duration of 100 ms for
filtering the error message.
7.2 Voltage errors at M12 slots (sensor short
circuit)
At every M12 input socket of the modules, pin 1 supplies a monitored sensor
voltage V
S
.
In the case of a sensor short-circuit, 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 "Surveillance Timeout" parameter.
7.3 Overload of output drivers
The output drivers of the modules with output functions (variants 16DIO,
16DO and 8DI/8DO) report an error when they detect an overload. This error
is reported by setting the relevant channel error bits in the diagnostic bytes.
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 one. Locked channels are deactivated
and remain in the
Off
state if you do not reset them using the controller.
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 "Surveillance Timeout" parameter.
