I quite suppose that operator guides 810 and 820 are similar.
But 820G GA3 (6FC3801-3AC-Z) on grinding machine tool "ASP400S-CNC" "Bahmuller", likely, has
Any features. For example: in the basic modes in the menu is not present SETTING DATEN on the display. And to change SETTING BITS, I pass such way:
DIAGNOSE>NC-STATUS>SETTIING DATEN>SETTING DATEN>SETTING BITS. There are features of adjustment of interface V.24. Also it is located not on the panel of the operator. Therefore there is a problem of communication with program PCIN. At all how in 810G.
