I need to write values to from the plc to my db a bit faster and with more handshaking than I get with the SQL Bridge. I want some advice so I don’t get started wrong on this.
I’ll have a bool tag in the PLC to say I’m ready to send the data. Should I just use memory tags for handshaking and read/write them from my script to control the flow?
Are there pros/cons to having the script be a tag-event script that triggers when the PLC is ready vs. it being a GW script that monitors the status of the trigger? I have enough time that I can afford to only check 1x/sec or so. Are there considerations for each approach?
Any “best practices” I should be aware of?
