I want to connect my delphi aplication progam to terminal port of Modicon TSX Micro 3722 through PCU 1030 cable. It's idea based on capability PL7 Junior as Human Machine Interface to get various data from PLC, but my idea more simple. I want to configure my PLC program to send character strings to terminal port using command (example): PRINT_CHAR(ADR#0.0.sys,'characters to be sent',%MW100:4) and my PC configured to recieve data from COM1/2. Unfortunately, my idea doesn't work, I just recieve series control characters which displayed as '|'. I do not know about my mistake. Should I use driver program to drive PCU 1030 to working properly ? and if yes, where I can get it (for free ) ?
Or i must use RS485 to RS232 converter to connect my PLC and PC ?
Thank you for enlighment ...
