Result Parameters - Siemens SINUMERIK 840D sl Programming Manual

Parameter description
2.2 Parameter overview
Parameters for logging only
Parameter
_PROTNAME[ ]
_HEADLINE[ ]
_PROTFORM[ ]
_PROTSYM[ ]
_PROTVAL[ ]
_DIGIT
Variable
In addition to defining parameters for calculation or character string input, there are also
BOOLEAN type variables. These bits can be used to vary planned cycle sequences or
enable or disable certain settings. These cycle bits are arrays of variables and of two types:
• Central bits: _CBIT[ ]
• Channel-oriented bits: _CHBIT[ ]
Their name defines their validity and occurrence:
• Central bits
• Channel bits
An overview of central and channel-oriented bits is given in Section Data description, cycle
data.
These bits can also be changed by programming or operation.
