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.
