28241 MAXNUM_SYNC_DIAG_VAR
- Maximum number of diagnostics variables per synchronized action DWORD
-
- -
Description:
Maximum number of diagnostics variables per synchronized action.
28250 MM_NUM_SYNC_ELEMENTS
- Number of elements for expressions in synchronized actions
-
- -
Description:
The expressions of the motion-synchronous actions are stored in memory elements in the
control. A motion-synchronous action occupies at least 4 elements.
It occupies:
●
1 element for each operand in the condition
●
>= 1 element for each action
●
2 elements for each assignment
●
1 element for each further operand in complex expressions.
One element occupies approx. 64 bytes.
The option "Synchronous actions stage 2" is required if the MD can be written to.

- Number of FCTDEF elements
-
- -
Description:
Defines the number of FCTDEF elements.
28253 MM_NUM_SYNC_STRINGS
- Number of strings for expressions in synchronized actions
-
- -
Description:
The expressions of motion-synchronous actions are saved in memory elements for storage
in the control. Elements have to be reserved specifically for strings within
expressions.
28254 MM_NUM_AC_PARAM
- Dimension of $AC_PARAM.
-
- -
Description:
Panel size of $AC_PARAM.
28255 MM_BUFFERED_AC_PARAM
