Accuracy of time synchronisation
The maximum time deviation between the functional
stations is 5 s.
Set cycle time
The display system provides one set cycle time function block
ST01. The set cycle time function block is a supplementary
function block for the PID controller.
The set cycle time function block provides a fixed cycle time
for processing the circuit diagram and the function blocks.
Wiring a set cycle time function block
The ST set cycle time function block is integrated in the
circuit diagram as a coil.
Figure: 129:
Display system circuit diagram with enabling of set
cycle time function block.
Parameter display for set cycle time:
The parameter display is used to modify the set cycle time,
the minimum on time and the enabling of the parameter
display.
Time range
h
To prevent unpredictable switching states, use each coil of
a relay once only in the circuit diagram.
