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.
2.2.2
Result parameters
Result parameters are measurement results provided by the measuring cycles.
Parameter
_OVR[ ]
_OVI[ ]
If the result parameters (_OVR[]) are used as input or transfer parameters for other standard
or measuring cycles, the ranges of values defined in the "Fundamentals" Programming
Manual apply.
The following specifications apply to angular values (in accordance with the "Fundamentals"
Programming Manual):
● Rotation around 1st geometry axis: -180 degrees to +180 degrees
● Rotation around 2nd geometry axis: -90 degrees to +90 degrees
● Rotation around 3rd geometry axis: -180 degrees to +180 degrees

INTEGER
Note
If the angular values to be transferred are smaller than the programmed calculation
resolution in the NCU, they are rounded down to zero.
The calculation resolution for angle positions on the NCU is specified in machine data
10210 $MN_INT_INCR_PER_DEG.
→ NCK:
once present, applies for all channels
→ CHAN:
extra for each channel.
