Parameter window A: Safety
All settings for the
Safety
function are undertaken in this parameter window.
This parameter window is visible if the parameter
Enable functions "priority and safety operation"
has been
enabled in
Parameter window
A: Function
, p. 71
The forced operation (a 1 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 parameterized reaction on bus voltage
failure and recovery has a higher priority.
Enabling of the three communication objects
Safety Priority x
(x = 1, 2, 3) is undertaken in the
General
parameter window. Monitoring time and the telegram value to be monitored are set in this window.
If a telegram is not received within this monitoring time, the output will assume the safety position.
This is determined in parameter window
A: Safety
, described below.
In contrast to the three safety priorities, each output has a communication object
Forced operation
.
Forced operation can be activated or deactivated via a 1 or 2 bit communication object. Using the 2 bit
communication object, the output state is defined directly via the value.
The contact position after the safety function ends can be set using the parameter
Reaction when forced
operation and all Safety Priority x end
.
