You have right i use the same cable and with PCIN work perfectly but not with STEP5. Today i even try with the newest software I use STEp5 v7.23 with hotfix but effect was the same PLC Timeout:-(.

This is strange every experts that i ask says that with 810T is possible download PLC program into STEP via normal data cable but in my machine this is false...

I have no other option I need to findsomewhere a cable TTY. Where i can find cable with (tty20mA) RS232(db9)-LPT(db25)?

With regards,
