I am a vb novice but I have to do a design as part of an electrical
engineering project.
This is the basic format of the program:
1. 30 plc are out in the field at different locations collecting
specified information.
2. The information from each must be written to a server
3. The server can now retrieve this information, view it, ammend in
and send it back to the related plc so the it may be displayed.
Questions
Can I set up a database with one file to retrieve the various
information from all plc?
How do I tell the plc what address to write to
How do it know what address to receive information on a specific
plc
How do I send information back to a specific plc
Any assistance will be appreciated thanking you in advance
