Ridici jednotka Modicon TSX Nano ztraci obsah RAM - snad vyreseno

[Jiri Sladek]

Tak jsem nasel manual, ktery nam snad pomuze.
     http://www.is-com.ru/files/Nano07_p.Pdf

Tam jsem konecne nasel popis checkboxu Master:
   The Master option lets you set the application in the EEPROM as the 
master, which
means that each time you power up, the PLC compares the application which is
present in RAM with that in EEPROM and, if a difference is detected, the 
application
stored in EEPROM is copied to the PLC RAM, and the PLC is set to RUN.

Dekuji vsem za rady.

P.S. Toto zarizeni (TSX 07 31 2412) nema od vyrobce slot pro druhou 
(vymenitelnou) baterii,
muselo by se bastlit, zapasit s tuhymi zapadkami atd.
