2.2 Userdefined auxiliary functions

Basic logic functions: Auxiliary Function Output to PLC (H2)

Function Manual, 11/2006, 6FC5397-0BP10-2BA0

Parameter: Address extension

The functionality of the address extension is not defined in user-specific auxiliary functions. It

is generally used to distinguish between auxiliary functions with the same "value".

Grouping together auxiliary functions

If all the auxiliary functions of the same type and value are assigned to the same auxiliary

function group, a value of "-1" must be entered for the "address extension" parameter.

Example:

All user-specific auxiliary functions with the value "= 8" are assigned to the tenth auxiliary

function group.

MD22000 $MC_AUXFU_ASSIGN_GROUP[ 1 ] = 10

MD22010 $MC_AUXFU_ ASSIGN_TYPE[ 1 ] = "H"

MD22020 $MC_AUXFU_ ASSIGN_EXTENSION[ 1 ] = -1

MD22030 $MC_AUXFU_ ASSIGN_VALUE[ 1 ] = 8

Parameter: Value

The functionality of the "value" parameter is not defined in user-specific auxiliary functions.

The value is generally used to activate the corresponding PLC user function.

Grouping together auxiliary functions

If all the auxiliary functions of the same type and address extension are assigned to the

same auxiliary function group, a value of "-1" must be entered for the "value" parameter.

Example:

All user-specific auxiliary functions with the address extension "= 2" are assigned to the

eleventh auxiliary function group.

MD22000 $MC_AUXFU_ASSIGN_GROUP[ 2 ] = 11

MD22010 $MC_AUXFU_ ASSIGN_TYPE[ 2 ] = "H"

MD22020 $MC_AUXFU_ ASSIGN_EXTENSION[ 2 ] = 2

MD22030 $MC_AUXFU_ ASSIGN_VALUE[ 2 ] = -1

2.2.5.3 Parameter: Output behavior

Function

The "output behavior" of user-defined auxiliary functions can be parameterized via the

machine data:

MD22035 $MC_AUXFU_ASSIGN_SPEC[ index ] (specification of output behavior)

For a description of the individual output parameters, see Section "Parameter: output

behavior" of the predefined auxiliary functions. The information given there can be applied

analogously to the output behavior of user-defined auxiliary functions.
