Procedure
Tip
Equipment Manual OP7, OP17
Release 04/99
Once the tests in OFFLINE mode have been performed successfully, the OP
is tested in conjunction with the PLC that you connected. This test deter-
mines whether the correct data areas have been configured.
Step
1 Connect the OP to the PLC.
2 Proper connection is indicated on the OP by a corresponding
message.
3 Acknowledge this message.
4 Switch the OP to ONLINE mode by means of the standard screen
System settings
You can now test all items in your configuration for which
communication with the PLC is necessary. Depending on the
configuration, this might be
event and alarm messages,
buffers for event messages and alarm messages,
print functions,
automatic message printout,
screen selection, etc.
The OP17 has the built-in "loop-through mode" function.
The loop-through mode facilitates testing with the PLC during commissio-
ning since there is then no need to keep on plugging the configuration com-
puter alternately into the PLC and the OP.
