I need to link a PLC5/30, Panelview Plus 700 and a barcode scanner (currently RS232).
My original plan was to use RMTIO between the PLC & PVP, but I now see the RMTIO requires an additional comms module ($$$). Communications via RMTIO appears deprecated, as they only mention it in chapters devoted to porting application from older systems.
The PVP comes with one serial port, and RSLinx Enterprise installed. From what I can see of the setup screen it only allows the serial port to be configured with DF1 protocol (i.e. for commms with a PLC), so you have no access to the raw RS232 data stream (and for that matter, the programming ability to parse raw data stream seems lacking).
I can see three options:
1. Purchase RMTIO adapter for PVP. Use RMTIO between PLC & PVP. Use serial port for comms with RS232 scanner. Still not clear how to communicate with scanner. Do I need to create a "3rd-party" OPC server? If so, is it possible to download this to PVP?
2. Use DF1 between the PLC and PVP. Replace serial scanner with USB scanner. It is not clear how to access data from USB scanner within PVP application.
3. Use DF1 between the PLC and PVP. Obtain an additional serial card for the PLC for RS232 comms to the scanner, and implement simple comms protocol in the PLC.
Any recomendations/comments appreciated.
Cheers,
