Sorry, my post will be in english. I'm looking for someone with experiance with B&R PLC, specifically old black series PLC with CP32 processor and TTY communication. It's programmed in DOS software called ProSYS and all of the program is written in kind of IL, but in may be plain assembler too.
I'm tring to communicate with the PLC by RS-232/TTY Converter and send/read values through.

Do you have any experiance with old B&R stuff? COuld you give me some help about commands which I should send to PLC. Maybe you know how the data frame is build? Thanks for any help.
