Configuration and operation
The free function blocks are configured at the parameter level. The following parameters are
required for this:
● Input parameters (e.g. inputs I0 ... I3 for the AND function block).
● Output parameters (e.g. output Y for numeric change-over switch NSW).
● Adjustable parameters (e.g. pulse duration for pulse generator MFP).
● Runtime group (this includes the sampling time; the free function blocks are not
● Run sequence within the runtime group.
A parameter is assigned to each input, output, and adjustable variable. These can be
accessed with the STARTER commissioning software or via the BOP. The "free function
blocks" can all be interconnected at BICO level.
The "free function blocks" do not support data set dependency.
Runtime group, sampling time, and run sequence
Runtime groups
Runtime groups are groups of free function blocks within the system that are computed in
the same sampling time and at a specific time.
A total of 10+1 "runtime groups" (runtime group 0 to 9 and runtime group 9999 (= runtime
group is not computed)) are available for which the sampling time can be set in specific
intervals.
Each function block is assigned one runtime group via a parameter. In the factory setting, the
value 9999 (i.e. the function block is not computed) is assigned to each function block.
Example:
For function block ADD 0 (see the SINAMICS S110 List Manual, function diagram 7220), the
runtime group is set in p20096.
The runtime groups are divided into one "fixed runtime group" and several "free runtime
groups".
● The "fixed runtime group" is called at a defined point in the system runtime. The sole fixed
● The "free runtime groups" are only defined via their sampling time.
Note
If the same sampling time is assigned to two or more runtime groups (the same fixed or
free runtime group), the runtime groups are processed in numerical order.

computed in the factory setting).
runtime group (p20000[x] = 9003) is arranged before the setpoint channel and calculated
in the sampling time of the setpoint channel (4 ms). This set value is only available for the
SERVO drive object type.
