Re: Reading data from a SIMATIC.S7-1500 PLC

I have a request to read data from a Simatic.S7-1500 PLC directly from an
RPGLE program and return data back. Has anyone done this before? I
haven't had any luck searching for solutions via Google.

The application flow is as follows:


1.
Camera scans barcode on product and writes serial number to PLC.
2. RPGLE reads serial number on PLC.
3. RPGLE retrieves serial number data from iSeries tables and writes
data back to PLC.
4.
PLC sends iSeries table data to printer.
5.
Printer prints iSeries table data on box.

I currently use an application called UaExpert to see the data being
captured on the PLC. Not sure if the screen shot will come through but
if it does, I need to read the data in the string_Seriennummer field in the
stOut Address Space. I need to update the fields defined in the stIn
section of the Address Space.

Any direction would be appreciated.
