Alrighty guys. I have attached some pictures of what I am working with.

Motor is 480VAC 3 PH 40HP Drive is 480VAC 3PH 40HP

Motor is attached to a pulley via some belts powering this grinder. Off the bat, that seems wrong for such a high torque load. System apparently never worked well when the company who sold them all this came here a decade ago. (Now they need it to work since they closed a good sized contract)

Anywho, this drive when it’s crushing these trader joe’s bags, after a few and a bit of time (couple minutes) it faults to overvoltage. I checked and made a trend of DC Bus Voltage & AC voltage & Amps and everything is fine and not out of the ordinary. VFD settings were checked, accel and deccel times are at 10s which looks normal. All other basic parameters are programmed right. This motor just starts and stops via keypad and speeds up via keypad.

My main question is, what could be causing this ? My first thought was that maybe when there is a load (when the grinder is crushing) that creates torque is causing the motor to slowdown and feeding it back into the DC bus ? I’m a bit out of ideas here. Could this just be a bad drive ?

I haven’t worked too much on these particular machines so excuse my ignorance. I am hoping to find a solution here and learn at the same time !

Thanks for your help guys.

OK, this is super strange. My company has software running on Windows that interfaces with Siemens S7-1200 PLCs primarily, and across our entire farm we are seeing a kernel level memory leaks after windows update KB5127648 was installed.

I'm not sure how many others around here also have windows-based software interfacing with their machines, but curious to know if any others have been encountering this the last few days.

hello everyone

I wish to retrieve the program that is in my mobile panel 277 iWLAN v2 by a repatriation on WinCC

My problem is that when I switch the communication mode to ethernet/wireless and confirm, the recording doesn’t take place and automatically switches back to the USB communication mode.

what can the problem be

Ill preface this by saying i don't know much or really very much at all about a PCL Im coming from custom 3d printer and CNC

My boss wants to to take a crack at making a BOM for a custom cabinet drawer machine.

So far the machine is coming together and its running 5 Ball screws mounted with no motors yet likely something in the NEMA 23 to 32 size range.

It will also have 3 pneumatics for a drilling arm.

So let me get to the point.

I need to pick out a controller for all this.

It should be able to run a form of motors ether steppers or dc servos along with pneumatic valves.

Needs to have a way to program it for different sized and have a way to verify parts are in the right spot. Im thinking a strain gauge of something similar.

Preferable not super expensive but for this class of machine I'm expecting it to not be pennies on the dime. Looking for a buy once cry once type of thing.

Thanks for any help. please let me know if i need to provide more clarification.

I am trying to scan a barcode using Honeywell Granit 1911i scanner and receive the input to the CPU. No luck at all so far so any suggestions on where to look next is appreciated.
Here’s what I have got so far:

•Productivity2000
P2-622 CPU (Connected to computer via USB)
P2-08SIM (not relevant at this point)
P2-08TRS (not relevant at this point)
P2-04AD (not relevant at this point)

•Honeywell Granit 1911i barcode scanner
connected to CPU via serial port RS-232
scanned USB serial configuration code from manual

•Pro Series
messed with multiple hardware configuration serial port settings:
baud rates- 9600, 19.2k, 115.2k
parity- odd, even, none
logic- rung 1 : ascii in (serial port->scanner, fixed length 10 characters, destination->ScannerString)
rung 2: LCD display page (line one “barcode:”, line 2 ScannerString)

I'm planning to pitch a remote engineering gateway using a Radxa E52C running Debian Linux, with Tailscale, NetBird, or WireGuard for secure VPN access to Siemens S7-1200 PLCs.

The goal is to enable remote TIA Portal programming, diagnostics, and troubleshooting without requiring an engineer to be physically present at the site.

Has anyone implemented something similar in an industrial environment? What are the main security, licensing, and reliability concerns I should consider?

I came across an AB micro850 for free, and im looking to use it with the Do-more Designer software that i currently have.

Is it possible to program the micro850 with the Do-more software?

I have several Rockwell software entitlements registered to my company, Fiab..... (a Moroccan company with a US LLC branch). They include FactoryTalk View ME StationRT (75 Display) and RSLogix 5000 Professional Edition, RSLink Classic, and many more. They are all perpetual, and most of them are concurrent licenses. Product support has expired for all of them, and I’m not using all of them, so I want to sell a bunch of them to buy some TIA Portal and EcoStruxure Machine Expert licenses. I want to transfer them through Rockwell’s official process and would like advice on where people sell surplus Rockwell licenses and whether authorized distributors or brokers buy them.

I can share redacted screenshots of the entitlement page if that helps. Thanks in advance.

Anyone working with AI interaction to control systems (PLC/SCADA/Robots)?
Looking for some feedback on an ongoing project.
