alarm setpoint relates to setpoint of alarm

alarm (3...10) assigned to channel; alarm is
active if all channels are in alarm state
20 Alarm assigned to all channels; for each
channel, alarm setpoint relates to setpoint of
alarm (3...10) assigned to channel; alarm is
active if at least one channel is in alarm state
21...28 Alarm assigned to channel 1...8; alarm
setpoint defines a symmetrical event
window around the setpoint of alarm (3...10)
assigned to channel
29 Alarm assigned to all channels; for each
channel, alarm setpoint defines a
symmetrical event window around the
setpoint of alarm (3...10) assigned to
channel; alarm is active if all channels are in
alarm state
30 Alarm assigned to all channels; for each
channel, alarm setpoint defines a
symmetrical event window around the
setpoint of alarm (3...10) assigned to
channel; alarm is active if at least one
channel is in alarm state
31 AND function for multiple alarms (3...10)
32 OR function for multiple alarms (3...10)
Note: if U=1, alarm tripping under channel
conditions OR and AND is reversed from
9 to 30.
(*) For symmetrical alarms with negative hysteresis,
hysteresis is placed inside the window, whereas with
positive hysteresis it is placed outside.
The minimum alarm (positive hysteresis, type 1 event)
is automatically excluded in the startup phase until the
input variable has exceeded the set limit.
