I have a project where I communicate with scales via modbus TCP. The scales get powered down when the line is idle.
As you can see I have 2 different tag quality indications. Line 7 is Unknown, and Line 8 is Bad Quality. In both cases, the driver status is the same; toggling from Connecting to Faulted.
So why do I have two different qualities?
My guess is that Line 7 has been offline since the modbus driver started, and Line 8 communicated for a while and then powered down. But the Ignition gateway has been running uninterrupted for a month. And Line 7 has definitely been online more recently than that.
I have not made any changes to tags, which I’m sure would reset statuses. I have made changes to graphics and scripts, and published the project. Would that publish reset the modbus driver, or the tag statuses?
