or did you press
key combination?
After the power supply has been turned on, the OP performs a self
test.
In the test, it checks the operability of the most important device
components and displays the test results.
If there is not a configuration on the OP, the OP switches automati-
cally to Download mode.
The OP then performs various internal initializations.
In this start-up phase, the OP attempts to establish a connection to
the PLC.
If communication is not possible – for example, because the cable
to the PLC has not been inserted – the OP displays a system mes-
sage.
After start-up, the OP is at message level.
