Configured data blocks can be inhibited via keyswitch by setting these bits
(see also WS 800A description).
The keyswitch can be used to prevent the entry or modification over the NC
operator panel of the following data by setting the corresponding bit(s):
Zero offset (G54 - G57) fine
R parameters angle of rotation zero offset (G54 - G57) coarse
TO wear (parameters P5 to P7)
TO geometry
Bits 2 and 1 are effective only when the standard display for tool offsets
(P0 ÷ 9) is not modified in any way. When configuring tool offsets, the
keyswitch group (bits 5 to 7) for the data fields (P0 to Pxy) must also be
configured via the NC workstation (WS 800A). Bits 1 and 2 can only be set
together or not at all.
