I/O Channel (PII, POI)
Brief Description
The I/O channel is MLD's contact to external devices as it allows
evaluating and addressing digital and analog inputs/outputs.
Fig. 5-11:
I/O channel (PII, POI)
The I/O channel has the following features:
•
Inputs and outputs are in the respective process image.
•
There is one common process image for all tasks.
•
The PLC works in word-oriented form according to IEC1131.
•
Update of process image inputs
(PII) max. T
PLC
/2 (500 µs for ADVANCED) before the PLC task. For
inputs which are read via the master communication or via CCD, the
update of the process image inputs is additionally delayed by the
corresponding bus cycle time.
•
Update of process image outputs
(POI) max. T
PLC
/2 (500 µs for ADVANCED) after the PLC task. For
outputs which are written via the master communication or via CCD,
the update of the process image outputs is additionally delayed by the
corresponding bus cycle time.
•
Distribution of physical inputs/outputs between drive and PLC is
possible via IDNs (parameters).
•
Changes in the I/O configuration take effect after switching from
parameter mode to operating mode.
•
I/O channel is configured by means of IndraWorks dialogs.
•
To be observed:
Only those inputs and outputs used in the program
are updated.
