Abstract:The PLC is a composing part of Infranet, it links to the
measuring instrument and device in field control layer
directly, and is the footstone of factory automation system.
Therefore it is very important to realize the communication between
PLC and monitoring layer computer for optimization
of syste running. The paper discussed the related communicat
ion problems between Delta DVP PLC and monitoring computer
based on Visual Basic.
