8.6 H function
Functionality
H functions can also be used to transfer floating point data (REAL data type, such as arith-
metic parameters, see Section “Arithmetic parameters R”) to the PLC.
Which meanings the values have for a certain H function is defined by the machine
manufacturer.
Programming
H0=... to H9999=... ; Max. 3 H functions per block
Programming example
N10 H1=1.987 H2=978.123 H3=4 ; 3 H functions in a block
N20 G0 X71.3 H99=–8978.234 ; with axis motions in the block
N30 H5 ; corresponds to: H0=5.0
Note
In addition to M and H functions, T, D, and S functions can also be transferred to the PLC
(programmable logic controller). In all, a maximum of 10 such function outputs are possible
in a block.
