Hello,
I have seen that often in programms for the stepping inside the
files is done the following:
First Step
--XIC B25:1/0--------------------L-B24:1/1------
for the next stepp
--XIC B25:1/1--------------------L-B24:1/2------
------------------------|--------U-B24:1/1------|
In the main programm is one copy command that copy
all the bits from B24 to B25.
So the second step will only be done, if the slc has copied
the B24:1/1 to the B25:1/1 (inside the main file).
Is this normally for the PLC/SLC programming to do only one
step per fileat every scan of the cpu?
Is this neccessary?
