2.8.23.4 Variables (Cent’d)
When the finish signal is not waited for, the
distribution end signal (DEN) is not transmitted.
In this case , the FIN is waited for in the block
with the check skip cleared. Hence, when the
FIN is not waited for, be careful not to specify
the next auxiliary function.
e. Clock (#3001 , #3002)
i.
When system variable #3001 or #3002 for clock
is specified,
