Program
When the data is received at frame no. 1 , link relay L001 turns on during 1 scan. At that moment M000 increases .
and the value of M000 moves output relay P004.
The new value of M000 is sending again every 1 second period (F092 is 1second period flag)
The number of sending normally stores D000.
When error occurs, the number of sending error stores D001.
When data is received , K7 search the same protocol at frame list automatically.
Therefore K7 has not receive instruction
(If the same protocol exist, K7 receive the data at the upper frame number. )
