Is this something you built yourself? Seems like there is a growing need for this

DISCLAIMER: I work here, but the product fits what you're discussing. We have a Gateway device that will accept wireless signals and Modbus (RTU and/or TCP) and can publish the data to an MQTT broker which can then be connected to a cloud platform. The device also lets you output data...

INSANELY vulnerable. Not even kind of kidding, and it is SCARY. And you may be thinking in terms of cloud connections and remote access.... While those are risks, legacy PLCs are essentially open doorways to our world's most critical infrastructure. If you have not already, please look...

As someone who may have an actual need for this tool, thank you!

So to answer your question, in my personal opinion, stick with Modbus TCP and just find converters if/when needed. Also, if someone asks for a protocol that is not Modbus, ask them why. Sometimes people just like the "cool new thing" - but Modbus is still pretty damn cool!

This is a very interesting subject, and the answer really depends on the exact application. For example, EtherNet/IP uses UDP instead of TCP which means it is super fast, and is a good fit for factory automation and/or M2M synchronization. As more companies begin to combine their factory and...

Your question is too generic to provide helpful tips. An HMI is a "Human Machine Interface" which, by definition, is quite literally anything that allows a human to Interface with a machine/computer. There are hundreds of brands, thousands of models for industrial HMIs. The PRIMARY purpose...

Without knowing the details of the law/rule, it is very likely users will be forced to upgrade their RTU devices over to Modbus TCP. Uses the same RTU packet, but encapsulated in a TCP packet which is secure. There are already PLENTY of adapters for legacy instruments. OR..... They force...

What do y'all specialize in? Any "exotic" metals? Have any 5-axis CNC's? Could always try subcontractor jobs through Raytheon, Northrop Grumman, etc. If you cut metal for the war machine, that is as consistent as you can get. The government still orders metal parts for vehicles...

I neither work for nor am affiliated with them, but KROHNE makes Coriolis meters (even straight tube) that boast entrained gas management so they will still read accurately. Check out their "OPTIMASS" line

Here's a practical problem for you! Nothing too crazy, but it's a PLC program you will likely write a million times lol Application: "Lift Station Monitoring and Control" A lift station has two pumps, a radar level sensor, and two backup floats. When the level in the wet well reaches 8...

It is hard to tell without knowing what exactly isn't working. If the logic just isn't doing what you think, I would remove timers, unless used as a failsafe. Your writeup mentions using level switches to determine when full and to start the conveyor again. Since you have a sensor for the...

Not an expert, just like to learn new things and help others in the industry. Here are some resources that may help! https://www.gevernova-education.com/momentum/index.php https://www.gevernovatechtraining.com/momentum/course_details.php?ctid=241

If you cannot send the meter out for proper calibration and adjustment, you can do a quick spot check by using another (known/good) flow meter to compare it against and then simply rescale the output. I've done this for customers in the past with a clamp-on flow meter to test against. Not...
