I'm trying to get data from a scanner(third party) using RS232 protocol. Siemens hardware is a ET200SP IM155-6PN remote device with CM PtP that is configured with the default RS232C configurations with S300 CPU319 as main PLC. The scanner also happens to have the same default configurations. At some point I was getting the raw data until I changed the pointer for the receive buffer, from there on I stopped receiving the data. I even changed the PLC program to the original state but still no data is coming through. The block that I'm using to receive data is FB614: RECEIVE_P2P. There is no error, the message that I'm getting from the STATUS is 16#7002: Interim Call: Data transmission running, according to the documentation but it doesn't tell me much about how to resolve it. I doubt hardware configuration changed nor the scanner configuration for that matter, so now I don't know whether the problem is in the scanner, HW config or PLC program. PLC program being the only thing that changed according to my knowledge. Now I will try reconfiguring the scanner and also try dynamically configuring the CM via user program using the FB611:Send_Config block. I have attached the relevant screenshots of PLC code, DB Struct and HW configuration. Any suggestion. Thank you.
