Love it! This was awesome to see. Would love more videos like this. We have things like this in our plant. Might even be able to incorporate this in other parts of the plant too.
I can only emphasize in all the ways that video like this which actually shows an actual live programming example are very worth it to try to get the point across of how something works and in using the correct instruction. As well an instruction can be written more than one ways as well. But equally important is taking the time to explain the given example and showing it as things go back and forth. It allows a person watching to learn and figure things out even if they have the watch the vid a few times. Which is the real point of making the video. However, it was nice to see the simulator doing what a simulator does. And reminding myself seeing it, that with the programming we do at the office that I can have the simulator connected to simulate analog input for testing.
Thanks, I tried a few like this years ago but a few jerks complained that I spent too much time describing what could go wrong instead of telling them how to do it. The mistakes are where the learning opportunities are. Anytime I can simulate a process, I do these days. I spent a lot of awkward hours with the customer staring at me on the first trial of my code
@TimWilborne Your channel is a learning channel, thus the emphasis I think should be to learn from you teaching via showing. There could be more than one ways to do something or to write a ladder logic, but your just showing the most easiest simplified way. Testing via simulating is a whole lot more safe than trying to test logic on live equipment which can be highly dangerous. I think you know best what to do and just keep doing it.
The ControlLogix HART analog I/O modules support the HART protocol and perform these operations: • Conversion of 4…20 mA analog signals to digital numeric values in engineering units (such as kg, m, or percent) that are used in the Logix controller. • Conversion of digital numeric values in engineering units to 4…20 mA analog signals to control process devices. • Automatic collection of dynamic process data from the connected HART field device (for example, temperature, pressure, flow, or valve position). The 1756 Hart output modules Complete a PID loop. HART output modules (1756-OF8H, 1756-OF8HK, 1756-OF8IH, and 1756-OF8IHK) provide current or voltage output signals that adjust the settings of valves and other devices in accord with desired process behavior.
An example application is a HART enabled mass flowmeter. The standard mA signal from the flowmeter provides one primary measurement - flow. The mA signal with HART provides more process information. The mA signal that represents flow is still available. The HART configuration of the flowmeter can be set to communicate primary value (PV), secondary value (SV), third value (TV), and fourth value (FV). These values can represent mass flow, static pressure, temperature, total flow, and other conditions. Device status information is also provided via HART. Instead of one process variable, with HART the controller sees four process variables, has a check on the mA signal, and has a reading of device status. HART connectivity provides all this information with no changes to the existing 4…20 mA wiring.
The truth of the matter is, an E&I Technician Role entails knowledge / Experience with HART and the process variables. PID loops Etc. One may never encounter the use of this technology as a Industrial Maintenance Tech. Or even as a Controls Tech.

Glad to help out!

Love this video. At work we have mixers and sand transporters that we just use timers for. I may see if this will work with the bindicators we use.
Great, let me know how it goes.

Thank you for another great video.
You're welcome!

Yes, it is nice that it uses the existing wiring
