Hello As I said in my last post I have no communication with the NCU either via Step7 Simatic Manager or with HMI, have the alarm 120202. even make the reset sequence S4 (PLC) MRES-STOP STOP ("2" - "3" - "2"). I have to understand why the PF Led Blinks 8 times (PF PLC Watchdog (red), I find the manuals this information. as the NC-PLC data there is no problem data, have all the bach up Thanks Flopez Send Video https://youtu.be/QCkqyCp4Xp8 |
