Storing Data in Variables L900 to L951

The programming tools described in this chapter are necessary for creating subroutines
called by G functions (see Chapter 5).
3.1 General
Certain arguments or functions may have different meanings in the machining cycles
programmed. Status symbols [
•
IBE0(i)] and [
•
IBE1(i)] are used to detect their
presence in blocks including a G function calling a subroutine.
It is up to the subroutine to correctly address these arguments or functions according
to their meanings and to store their values in variables L900 to L951.
The bits of [
•
IBE0(i)] and [
•
IBE1(i)] (each equal to 0 or 1) are accessible for read by
parametric programming.
3.2 Storing F, S, T, H and N in Variables L900 to L925
Storing F, S and T
Status symbol [
•
IBE0(i)] consisting of a list of bits is used to detect programming of
F, S or T in blocks including a function Gxxx.
Index (i): from 1 to 26 for addresses A to Z.
Addressing the status symbol:
- bit [
•
IBE0(6)] is set if F is programmed,
- bit [
•
IBE0(19)] is set if S is programmed,
- bit [
•
IBE0(20)] is set if T is programmed.
The values of F, S and T are stored in the following variables (L900 to L925):
- F in L905,
- S in L918,
- T in L919.
Storing H and N
H and N can only be stored when not preceded by functions G75, G76, G77 or G79
related to them for ISO programming.
A second N (following the first N and defining the last call sequence of a subroutine
N.. to N..) is stored in variable L914 (this N can in no case be the block number
programmed at the start of the sequence).
Addressing the status symbol:
- bit [
•
IBE0(8)] is set if H is programmed,
- bit [
•
IBE0(14)] is set if the first N is programmed,
- bit [
•
IBE0(15)] is set if the second N is programmed.
