28241 MAXNUM_SYNC_DIAG_VAR N05 -
- Maximum number of diagnostics variables per synchronized action DWORD PowerOn
-
- - 0, 0, 0, 0, 0, 0, 0, 0... 0 10000 1/1 M
Description: Maximum number of diagnostics variables per synchronized action.
28250 MM_NUM_SYNC_ELEMENTS C02 2.8, 6.1
- Number of elements for expressions in synchronized actions DWORD PowerOn
-
- - 90 0 159 ReadOnly S
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.
28252 MM_NUM_FCTDEF_ELEMENTS C02 2.4, 2.8, 6.1
- Number of FCTDEF elements DWORD PowerOn
-
- - 3, 3, 3, 3, 3, 3, 3, 3... 0 100 1/1 M
Description: Defines the number of FCTDEF elements.
28253 MM_NUM_SYNC_STRINGS C02 -
- Number of strings for expressions in synchronized actions DWORD PowerOn
-
- - 200, 200, 200, 200,
200, 200, 200, 200...
0 32000 7/2 M
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 C02 -
