Output name
Function
Safe Position
Linked to
Safe Position
jump address. A stop is triggered by a logic
Low.
Inhibit Error Message
Linked to Inhibit Error Message jump address. This signal is logic
High when a
permissible error
occurs with the position data. The
position date is invalid when
sensor2 test
is active. In this case, the
Inhibit_Error_Message
signal stops a false entry being made in the
fault diagnostics history.
7.5.4.5
Message Generator function block
The
Message Generator
function block evaluates up to eight inputs. If a signal edge is
detected at one of these inputs in accordance with the configuration, the function block
sets the associated output to High for the duration of the logic execution and adds a
(user-defined) text message to the diagnostics history.
It can be read using the Flexi Soft Designer diagnostics function in online mode.
NOTE
If the voltage supply to the Flexi Soft safety controller is interrupted, this text message
will be lost.
