Application example:
In a process control system, two different
pH setpoints with different control parame‐
ters must be reached and maintained. The
system is controlled using a PLC. The
PLC indicates the required event signal to
the controller via a digital output. The con‐
troller then switches from
[Channel 1 parameter set 2]
to
[Channel 2 parameter set 2]
and then
maintains the relevant setpoint automati‐
cally.
[Parameter set 2]
must always be
activated from 22:00 to 05:00 Monday to
Friday irrespective of the PLC setting.
This is a combination of
[Event controlled]
and
[Time controlled]
operation.
Electrical connection
The external release signal can be
processed from digital input 2 (ter‐
minal XK1_3 and 4) or digital input 5
(terminal XK3_3 and 4).
