Program generator
Nine independent program generators are available as an optional extra (extra code 225 required),
meaning that nine independent programs can run asynchronously at the same time.
The following description applies for program generators 1 to 9.

Description
The program generator is switched off.
The program generator is controlled by a program.
The program generator operates as a fixed-set-
point generator. In this case, the setpoint values for
the basic status or manual mode are used.
The program starts at the first programmed set-
point value.
The program starts at the point at which the set-
point value corresponds to the current actual val-
ue.
A start time specified for program start is adopted
as the start time in a 24 h program.
Example:
Start time: 06:00:00; 24 h program from 00:00 to
24:00: The program starts at 6 a.m. and runs until
midnight.
Behavior of the program generator if measuring
range is exceeded or if there is measuring range
underflow (Out-of-Range)
Program continues to run.
The program is stopped.
