3.2.3.1.5 Parameter window
A: Safety
Commissioning
In this parameter window, all settings for the function Safety are undertaken.
This parameter is visible if in parameter window
parameter Function Safety has been enabled.
The forced operation (a 1 bit or 2 bit communication object per output) or
safety priority (three independent 1 bit communication objects per Switch
Actuator) sets the output in a defined state which can no longer be changed
as long as forced operation or safety priority is active. The parameterised
reaction on bus voltage failure and recovery has a higher priority.
The isolation of the three communication objects Safety Priority x
(x = 1, 2, 3) is undertaken in parameter window General. In this window, the
monitoring time and the telegram value to be monitored are set. If a telegram
is not received within this monitoring time, the output will assume the safety
position. The determination is implemented in the parameter window A:
Safety, which will be described in the following.
As a direct contrast to the three safety priorities, an independent
communication object Forced Positioning is available for each output.
The forced positioning can be activated or deactivated via a 1 bit or 2 bit
communication object. Using the 2 bit communication object, the output
state is defined directly via the value.
The switch state after the end of function Safety can be set using the
parameter Reaction when forced operation and all Safety Priority x end.
