Value Meaning
1 Activation enable ("Permission"):
The activation enable makes it possible to leave the neutral position of
the block in response to operator input or a command from the program
(CFC). The activation enable has no effect if the block is not in the
neutral position.
0 Interlock without reset ("Interlock"):
An active interlock condition brings the block to the neutral position.
After the interlock condition has gone, the currently active control func-
tion becomes active again in automatic or local mode. In manual mode
the faceplate can be operated again after the interlock condition has
gone.
0 Interlock with reset ("Protection"):
An active interlock condition brings the block to the neutral position.
After the interlock conditions are cleared, the operator or an activation
sequence must perform a reset to once again enable activation of the
control according to the input parameters.
