6.7 Auxiliary functions (H)
Auxiliary "H" functions are used to send information out to the PLC. They differ from the "M"
functions in that the "H" functions do not wait for confirmation that the function has been
executed in order to go on executing the program.
Programming
Up to 7 "H" functions may be programmed in the same block. The programming format is
H<0 - 65535>, and it can be programmed using parameters and arithmetic expressions. In
these cases, by default, the value calculated is rounded up to an integer. If the result is
negative, the CNC will issue the pertinent error message.
Execution
The auxiliary "H" functions are executed at the beginning of the block where they have been
programmed.
