These results remain valid at the outputs only until:
– the specification “Earliest start of output after triggering”
(system parameter) of the next started cycle has expired
and the signal at the “Triggering Signal” input of the next
started cycle has been cancelled
or
– the system parameter “Reset output at outputs after
expiration of Ignore triggering signal” = On and the time
“Ignore triggering signal after ready for operation” has
expired
or
– the system parameter “Reset outputs at outputs during
evaluation” = Yes has been set and a new evaluation has
begun.
Through the above conditions, it is possible to specify
minimum times for evaluation and output as well as influence
their starting time. A higher-level controller (PLC/IPC) can
thus start a new cycle and only then read the results of the
previous cycle. Such overlapping permits achievement of a
high evaluation rate.
The outputs of the output module of the I/O extension O0 to
O3, like the internal outputs, are configured via the system
parameters, that is, they are set or reset together with the
internal outputs.
