Hello!
I came across with an old Hitachi (Häwa) E20HRP PLC which i have to program. After a really detailed search on the internet i could barely find any useful information. It has a program port on its side with a 20 pin connector. I don't have a programming extention for it. Will i be able to program it straight from the serial output of the PC? If so, how should i wire a 25 pin connector?
Sorry if this is a noob question but i don't really have experience with PLCs.
