Hello all:
A while ago, my partner Sean and I (college students) had posted on the forums for help setting up our DH-485 network. We are trying to use the MSG command between PLCs. Is there a way to use it to turn on/off an output? We have tried a few different techniques, but no success. Is there a trick to it?
We have tried sending an integer (N7) from one PLC to another, but this does not work. Under the setup menu, what do we need to put under the following blanks:
-----------------
Write PLC:
This Controller:
Data Table Address____________
Size____________
Target Device:
Data Table Address____________
Local Node Address___ (is this the node that we want to send the value to?
-----------------
Read PLC:
This Controller:
Data Table Address____________
Size____________
Target Device:
Data Table Address____________
Local Node Address___ (what would this be for?)
-----------------
Please let us know what we should try, or possibly, post a link to some sample code on the web.
Many Thanks!
