Note
If your
communication blocks are called cyclically (for example, in OB1), it results in a slow
behavior of the web server integrated in SITOP PSU8600 due to high communication load.
If there are not any high demands regarding accurate time behavior, you can also c
all the
communication blocks in a time
-controlled block (for example, OB35).
