4.2.6.5 Rising edge evaluation (cycle pulse)
È
This function is used if the coil is only meant to switch on a rising edge. With
a change in the coil state from 0 to 1, the coil switches its N/O contacts to
the 1 state for one cycle time.

4.2.6.6 Impulse relay
ä
The relay coil switches whenever the input signal changes from 0 to 1. The
relay behaves like an impulse relay.

A coil is automatically switched off in the event of a power
failure and in STOP mode. Exception: Retentive coils retain
signal 1 (
￫ Section "5.9 Retention (non-volatile data storage)“,
page 181).
