Ok, I'm following you now... coffee is finally kicking in. I was going to suggest trying to edit the local policy if you weren't in a domain, but it sounds like you've tried it already. Unfortunately, like many MS 'features' it sounds like it doesn't work.

Understood about the production downtime, its my life as well. I'm not very familiar with your operation, but is there any reason you can't leave BC running 24/7?

I'm assuming you are using the embedded SQL DB, is that correct? With a mechanical drive, yes, I would expect that the DB would take a decent amount of time to get loaded to RAM (heavily dependent on drive RPM). I'm not very familiar with the embedded SQL DB, but I would think one could still...

PLC devices and components are purpose built for I/O processing, typically using ladder logic or function block programming (though several others exist). In my experience with AB/Rockwell/Siemens PLCs, you operate within fairly strict confines of the PLC, meaning you can't just load any old...

I think I found an issue with the graph time scaling recently added in 1.1.21. Adjusting the time scale from the configuration menu still works the same, so I know the data is there and accessible from the DB. I enable 'User Control' and attempt to change the time while locked. The graph...

I don't think so, but if the temperature is below the "icing" setpoint in the fins, the relay is going to stay interlocked.

If you were worried about BC communication interruption, you could keep the process on the same board by using 2 temp probes, and 2 hysteresis elements controlling 2 SPDT relays. Wire the heater circuit through the NC on 'FIN' relay to the NO on the 'Air Temp' relay and you've created an...

When you say two thermostats, do you mean one temperature probe for fin temp and one for air temp? To mimic the logic of the Coolbot, you would need to run a script. If I were doing it, I would use a hysteresis element reading the air temp to drive the heater (or direct drive the cooling...

The coolbot has a resistor that you tape to the AC thermostat to trick it into thinking its warmer than it is. It also has a sensor inserted into the fins of the AC unit to detect icing. I've been running one for nearly a decade now, and can confirm with enough insulation and properly sized...

I've been partial to the Intel NUC line... pretty sure I've seen fanless industrialized versions of them also.

Yes it should load data back from the SQL server. Look at the controller log file - Documents/BruControl/Logs - find the file from the day you restarted and look for the line about SQL connectivity. If there was a problem it'll display it there.

There is a folder Documents/BruControl/Config Backup... mine has daily config backups for about a month or so, taken at midnight... maybe you'll get lucky.

I'm using modbus via a RS-485 to Ethernet bridge, then I built a Node-Red flow to query/write data to some mass flow meters. BC interacts via the usual Global API path.

Those valves don't work directly from the PWM on the MEGA, you need an analog amplifier to convert the PWM to analog voltage.

Weird, If I drag center to the left or bottom and release outside the DE window, I don't get the error, but if I drag center to top or right I do. I'll get a video when I get back to my main desktop.

Yep, build 19 - I'll email you the contents... maybe it'll shed more light.

I found a bug with the Data Explorer that may or may not have already been noted. If you attempt a box zoom and pull the box outside the extents of the DE window, you get an Unhandled Exception. You can hit Continue and keep working, and everything seems to work fine, so its likely just a...

This isn't the exact one I have, but its very similar construction. Mine is a 'Covna' branded one, and overall it works fine, its just large, loud, and slow. The listing also doesn't indicate what the valve control method is, so you might have to contact them for options and further info.

I used a DPDT relay to reverse the polarity for the one I have. Otherwise you will need 2 SPDT relays and either use the double throw option in the firmware (not sure if this is operational yet, though), or use scripting to turn one relay off as the other one turns on. Ultimately for me, I...
