3.2.2.51 G130 Modal comparative operation, parameter field comparison
Modal or non−modal comparative operation with an effect on other modal
comparative operations
G130 X Z K I E Y V J
X First operand
Z Second operand
K Comparative operation
I Target block number
E Target program number
Y Number of modal comparison (0 ... 6) or, if not programmed, non−modal
comparison.
V Index of an optional customer−specific comparative operation
J Brakes
0: without ramp
1: with ramp (default)
G130 carries out a comparison K between the two operands X and Z. Both
constants and indexes of parameter fields are allowed as operands.
The comparative operations possible under K are
0 : X = Z X equals Z
1 : X > Z X greater than Z
2 : X < Z X smaller than Z
3 : X
≥
Z X greater than or equal to Z
4 : X
≤
Z X smaller than or equal to Z
5 : X
≠
Z X not equal to Z
6: (X
∧
2 Z ) = 0 Bit Z deleted in X
7: (X ∧ 2 Z ) ≠ 0 Bit Z set in X
In the case of a "true" result, all the on−going actions in the current NC
channel are stopped. Two variants of continuing the program are then
possible:
Program jump: The stopped actions are canceled and the program is
continued with block I. In this case, the code letter E must not be
programmed. The target block number I must be contained in the same
program in which the comparison is also programmed. If the target block
number I is not equal to the current block number N, a "true" result leads to
the deletion of all modal and non−modal comparative operations, which
were made on the same or subordinate program planes.
Subprogram call: The stopped actions are saved, program E is placed in
processing. In this case, the code letter E must be programmed; a target block
number I must not be specified. If the subprogram is processed, the control
continues processing at the interrupted position. A "true" result does not
lead to the export of modal or non−modal comparative operations.
