Implicite subprogram calls (G80G89/G800-G819)
G80 G89 [ [<val1>,<val2>, - ,<val10>] ] Sub program call (non-modal)
or in addition
G800 G819 [ [<val1>,<val2>, - ,<val10>] ] Sub program call (non-modal)
G8x / G8xx At the programming of G80G89 and G800-G819 an assigned global subprogram is implicitly executed. The default names of these subprogramms can either be configurated in the channel parameters [1]-45/ [1]-46 or defined during NC program execution by the command #FILENAME.
If at the programming of G80G89 and G800-G819 no assigned program name is available, the error message P-ERR-20131 "Unknown G function" is generated.
The global subprogram is called only once, this means G80G89 and G800-G819 has no modal effect.
<val1> , - , <val10> For the supply of a sub program (cycles) with additional data in an optionally following bracketing up to 10 parameters (mathematical expressions in REAL format) can be programmed in a fixed sequence. The parameters are separated by commas. Gaps in sequence have to be indicated by serially-ordered commas ", ," .
Analogous to the normal cycle programming in the sub program the parameters can be read via the @Px access. There is a fixed assignment between the transfer parameter and the @Px read access. (e.g. @P1 reads parameter value 1, @P2 reads parameter value 2 and so on). In this kind of so-called sub programms also the additional extended cycle syntax with the @ - character can be used. Weather a parameter is programmed (valid), can be checked in sub program (cycle) by the variable V.G.@P[i].VALID.
A G80G89 and G800-G819 is executed as the last action at block end. This means, axes motions programmed in the same NC block always are executed before the call of the global subprogram.
