Is there any good way to send actually messages to another PLC?
The MSG instruction isn't really a message it just continuously writes to a tag in a remote PLC. I want to be able to actually send a PLC a set of data only once, an then get an Ack back that that data was received.
Normally how this is done is you have a giant UDT that has tags and an Ack for every possible "Message" you may ever want to send. So you might have a UDT that has like 100 different Tags for like 20 messages, and all of that data is sent every all at once continuously.
