Programming of auxiliary functions
General structure of an auxiliary function
Letter[address extension]=Value
The letters which can be used for auxiliary functions are: M, S, H, T, D, F.
An address extension only exists for the H function. The address extension must be an
integer. The square brackets can be omitted when an address extension is specified directly
as a numeric value.
The value is defined differently for the individual auxiliary functions:
●
INT= integer
●
REAL= fractional decimal number (floating point)

A maximum total of 10 auxiliary functions may be programmed in one block. Alarm 14770
"Auxiliary function incorrectly programmed" is output when the specified length for address
extension of value is exceeded or when the wrong data type is used. The following table
shows some programming examples for H functions.
If the admissible number of auxiliary functions per block is exceeded, alarm 12010 is issued.
