6.3 Interfaces and signals
Signals for triggering the muting function
This safety system requires two digital 24 V signals from a higher-level control to trigger
the muting function. These signals are part of the initiation sequence for the muting
function.
The first signal for requesting the muting function, MR (Muting Request – in the Flexi
Soft project file also: PLC_Request), detects approaching material with a rising edge
and remains at logical high while an interruption of the Type 4 electro-sensitive protec‐
tive device is expected.
The second signal, TE (Time Extension), changes its status in the opposite direction
from the MR signal.
