Operation
IN1 increases OUT. IN2 decreases OUT. The absolute value of IN3 is the ramp time in ms,
which
is needed to increase OUT from 0 to 32767. With positive IN3, the output range is
limited from 0 to 32767. With negative
IN3, the output range is between -32767 and +32767. If
both IN1 and IN2 are true, IN2 overwrites IN1.
Connections
IN1: boolean; ramp up
IN2:
boolean; ramp down
IN3:
16 bit integer (15 bit + sign); ramp time scale
OUT: 16 bit integer (15 bit + sign); ramp value
Event
Display function
Illustration
Operation
IN1 triggers the event. IN2 selects the fault, alarm or notice. IN3 is the event delay in ms. The
name of the event can be changed by means of
String1 (85.11) to String5 (85.15) using
DriveWindow.

Connections
IN1: boolean
IN2: Choice of alarm, fault or notice. The shown numbers must be connected as constants.
IN3:
16 bit integer
OUT: not used
Filter
Arithmetical function
Illustration
Operation
OUT is the filtered value of IN1. IN2 is the filter time in ms.
OUT = IN1 (1
- e
-t/IN2
)
Note
:
The internal calculation uses 32 bits accuracy to avoid offset errors.
Connections
IN1: 16 bit integer (15 bits + sign); value to be filtered
IN2:
16 bit integer (15 bits + sign); filter time in ms
IN3:
not used
OUT: 16 bit integer (15 bits + sign); filtered value
