Procedure
Fault diagnosis
15-4
If you want to replace a configuration already loaded on the OP with another
one, proceed as follows:
Step
1 Using a suitable standard cable, connect the configuration com-
puter (PU or PC) to the interface of the OP:
IF1A for OP7
IF2 for OP17
2 Switch on the power supply of the OP.
3 There are two ways to switch the OP to download mode:
While normal operation is in progress
By calling the standard screen System settings
Download.
If necessary, enter the password for the required password
level beforehand.
During the startup phase of the OP
When switching on the power supply of the OP, press these
three keys at the same time.
This key combination ("overall reset") deletes the configura-
tion memory.
The OP then switches to download mode and waits for data to
be downloaded from the PC/PU.
4 Start the download operation to the OP on the PC or PU. The OP
checks the link to the PC or PU. If a link is not available or if it
is not functioning properly, the OP issues a corresponding error
message.
If the link is in order, downloading of the configuration from the
PC or PU is initiated to the OP. In doing so, the present configu-
ration on the OP is overwritten by the new one.
As long as data are not being transferred between the PC/PU and
the OP, you can cancel Download mode by pressing
Once the configuration has been successfully downloaded, the OP runs up
again. If a start screen has been defined in the configuration, it is opened. If a
start screen has not been defined, the OP displays the standby message.
Any fault occurring during commissioning or in operation is normally dis-
played by means of an error message on the display of the OP.
You will find an overview of the most important system messages together
with notes on troubleshooting in an appendix to this manual.
