Description of the function
The status of output Q changes with each 0 to 1 transition at input Trg and if both S and R = 0, i.e. the
output is switched on or off.
Input Trg does not influence the SFB when S = 1 or R = 1.
A one-shot at input S sets the pulse relay, i.e. the output is set to logical 1.
A one-shot at input R resets the pulse relay to its initial state, i.e. the output is set to logical 0.
Either the input R takes priority over input S (i.e. the signal at input S has no effect as long as R = 1), or
the input S takes priority over input R (i.e. the signal at input R has no effect as long as S = 1), depending
on your configuration.

Connection Description
Input Trg You switch output Q on or off with a signal at input Trg
(Trigger) input.
Input S A one-shot at input S (Set) sets the output to logical 1.
Input R A one-shot at input R (Reset) resets the output to logical 0
Parameter Selection:
RS (input R priority), or
SR (input S priority)
Retentivity set (on) = the status is retentive in memory.
Output Q Q is switched on with a signal at Trg and is reset again at
the next Trg pulse, if both S and R = 0.
