G54.1P1 - G54.1P48

The data of the workpiece zero points from P1 to P48 are stored in the variable numbers #7001 to #7945. A corresponding calculation of the variable number is recommended here:

Berechnung

Variable number = 7000 + (P-Number - 1) * 20 + Axis number

Example for G54.1 P33

#1 = 33
#[7001 + [[#1 - 1] * 20]] (X)
#[7002 + [[#1 - 1] * 20]] (Y)
#[7003 + [[#1 - 1] * 20]] (Z)
#[7004 + [[#1 - 1] * 20]] (1)
#[7005 + [[#1 - 1] * 20]] (2)

Explanation

The zero point number has been temporarily stored in variable #1 to make it easier to reuse. The axis number is already included in the values from 7001-7005 and is not added additionally.

Example of use: Write

Writing values in G54.1 P33:

#1 = 33
#[7001 + [[#1 - 1] * 20]] = 55.32 (X)
#[7002 + [[#1 - 1] * 20]] = 352.887 (Y)
#[7003 + [[#1 - 1] * 20]] = -487.995 (Z)

Example of use: Read

Read the values of G54.1 P33 and save them in variables #11, #12 and #13:

#1 = 33
#11 = #[7001 + [[#1 - 1] * 20]] (X)
#12 = #[7002 + [[#1 - 1] * 20]] (Y)
#13 = #[7003 + [[#1 - 1] * 20]] (Z)
