Description:
The expressions of the motion-synchronous actions are stored in memory ele-
ments in the control. A motion-synchronous action occupies at least 4 ele-
ments.
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.
Description: Defines the number of FCTDEF elements.
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.
Description: Panel size of $AC_PARAM.
Description: $AC_PARAM[] is stored in SRAM.
