The following notation and abbreviations are used in this document:
S
PLC interface signals –> IS "Signal name" (signal data)
Examples:
– IS "MMC–CPU1 ready" (DB10, DBX108.2), i.e. the signal is stored in
data block 10, data byte 108, bit 2.
– IS "Feedrate/spindle override" (DB31–48, DBB0), i.e. the signals are
stored for specific spindles/axes in data blocks 31 to 48, data block
byte 0.
S
Machine data –> MD: MD_NAME (English designation)
S
Setting data –> SD: SD_NAME (English designation)
S
The character "8" means "corresponds to".
After data (e.g. machine data) have been changed, it must also be noted when
the change will become effective (e.g. after power ON or immediately). This in-
formation is therefore always provided.
