started up for the first time. Proceed as follows:

Caution
S
With the SIMATIC S5, compression of the internal program memory on
the PLC (PU "Compress" function, integrated FB COMPR) is not allowed
when an OP is connected. Compression modifies the absolute addresses of
the blocks in the program memory. Since the OP only reads the address list
during startup, it does not detect any address modifications and accesses
the wrong memory areas.
If compression is inevitable during routine operation, switch off the OP
prior to compression.
S
In hazardous areas, always de-energize the OP before unplugging connec-
tors.
Step
1 Switch on the OP power supply. As a configuration has not yet been
loaded, the OP automatically switches to Download mode and waits for
data to be downloaded from the PC or PU. The message READY FOR
SERIAL TRANSFER appears.
The OP cannot be operated in Download mode.
Connect the IF2 interface (RS232/TTY) on the OP to the PU or PC by
2
means of a suitable standard cable.
3 Start the download operation on the PC or PU to the OP. The OP checks
the connection to the PC or PU. If the connection is not available, or not
functioning correctly, the OP issues the corresponding error message.
If the connection is in order, downloading of the configuration com-
mences. The OP firmware is downloaded automatically.
Following successful downloading, the OP restarts and displays the start
screen of the configuration that has just been loaded.
Note
For information on which settings are required for the downloading operation,
please refer to the User's Guide ProTool Configuring Graphics Displays.
