Remark1:MC/MCE instructions can be used in nesting or
interleaving as shown to the right:
Remark2:•When M1918=0 and the master input changes from
0→1, and if pulse type function instructions exist in
the master control loop, then these instructions will
have a chance to be executed only once (when the
first time the master control input changes from 0→1).
Afterwards, no matter how many times the master
control input changes from 0→ 1, the pulse type
function instructions will not be executed again.
•
When M1918=1 and the master control input
changes from 0 → 1, and if pulse type function
instructions exist in the master control loop, then
each time the master control input changes from 0→
1 the pulse type function instructions in the master
control loop will be executed as long as the action
conditions are satisfied.
•
When a counting instruction exists in the master
control loop, set M1918 to 0 can avoid counting error.
•When the pulse type function instructions in the
master control loop must act upon the 0→1 input
change by the master control, the flag M1918 should
be set to 1.
