Setting and monitoring the sampling
times and sampling sequence
Example of the sampling time and sampling
sequence of a function block:
This function block has the function block number 314
It is deactivated in the factory setting (U953.14 = 20).
Uxxx (0)
K Kxxxx
U953.14 = __ (20)
Via U953.14 = 4 the function block can be allocated to the sampling time
T4 (= 16 x T0 = 3.2 ms at 5 kHz pulse frequency).
The function block is processed in the factory setting at the 3140th
position. By setting U963.14 to a value not equal to 3140,
the block can be allocated to a different position in the
sampling sequence.
Monitoring of calculating time

Parameter for setting the sampling time
Value range: 2 ... 20
Factory setting: 20 (applies to most blocks)
Parameter value Sampling time
