6. Function blocks
6.1 Manufacturer function blocks
Note on the minimum time setting:
If a time value is less than the program cycle time, the elapsed
time will not be recognized until the next cycle. This may cause
unforeseeable switching states.
Analog value and timing relay setpoint
If you wish to use variable values as a timing relay setpoint, such as an analog input,
the following conversion rules apply, depending on the time base configured.

Equation: Time setpoint = ( Variable value/10) in [ms]

You can only use analog values as setpoints if the value of the
analog input is stable. Fluctuating analog values impair a repro-
ducible timing response.
Signal Diagrams
The fact that the function block features various operating modes means that it can
work in more than one way as shown below.
How the timing relay works with the on-delayed operating mode with and without
random times
Random switching
The contact of the timing relays switches randomly within the SETPOINT value range.
