Customer demanded everything be in 0.75mm² (18awg)

🤨😳🥺😭😠😡🤬

I have to admit, I was wrong multiple times on this sub. I have been writing a program in ST on a Codesys platform the past week, cause that's what my customer wanted. ST really is the superior programing language... I'm sorry for doubting all of you nerds, I have joined you in the autism. I need not explain myself, if you know, you know. I am prepared to be downvoted by the non-believers and uncultured.

Hello, I'm a bit of a noob when it comes to this level of networking so looking for some help.

I have a project coming up with an Allen Bradley PLC with 5 AENTR IO racks in their own remote panels, 60 VFDs and 10 Modbus/TCP devices. I assume at this point I would need a Managed switch/switches to help deal with the traffic. All the VFDs will be setup with explicit messaging and the Modbus/TCP will be the built in AB AOI.

My main question is how important is it to have a managed switch in this instance? What would be the possible downfalls on going completely unamanged? On previous jobs and at other factories I've seen similar setups with nearly as many connections with all unmanaged switches and things seemed fine even after several years.

Es mi primera vez trabajando con este variador de LS electric, referencia LS-100 ya leí el manual como 3 veces y no encuentro el error o si falla algo más

I have been working on a Click PLC panel for a project where I’m filling tanks and moving water with a fill valve, a pump and a drain valve. I’m self taught, built the entire panel and am so close to perfect, and I have everything working in the PLC cabinet (relays, indicator lights, inputs all work) but I’m stuck on the very last detail I need to make this right. Currently my only issue is that my output for my fill valve and my output for my drain valve turn on and off at the same time. Pics show my addresses, data sets and the logic. Can anyone take a look and see what I’m missing here?

Order of operation on input button push:
1) drain valve on tank 2 closes, full light turns on
2) fill valve for tank 1 opens for 30 seconds, closes
3) pump comes on after waiting 10 seconds and stays on for 25 seconds to move water from tank 1 to tank 2, shuts off
4) after 40 seconds the drain valve opens back up (ready light comes on) and drain valve stays open until the button is pushed again

I want to jog a portal forward, backwards, up and down by pressing the corresponding button in the HMI when opening a screen in pop up. To do this faster i want to couple these buttons to the keyboard input z,s,q and D using the "hotkey" function. Apparently this does not work because i defined the jog by setting it on "press" event and resetting it on "release" event. The hotkey only works with the "click left mouse button" event (why Siemens...). But then the bit stays high... using the "press/release key" events also does not work because the botton must first be "focused" or something. I have not found a way to make this work, i think i have to script this but i have not much experience with that. Can somebody help me going in the right direction.

I’ve got a project coming up which requires around 15 intrinsically safe barriers for equipment in a hazardous zone. Some are digital outputs and some 4-20ma.
What’s the best way to do this, would you have 15 individual barriers or is there a better solution?

Looking for insight/suggestions. We have a customer who has a schneider PacDrive LMC201C currently running their system. They want to eventually get rid of it completely and switch to the AB. However they want to do it in a phased approach. So Phase one is replacing their current HMI software with Ignition. But we need to duplicate the aprox. 2300 tags the current HMI is using over in the AB plc. Which means you need a data connection from the Schneider to the AB. How would you recommend doing that? In later phases we would be stripping control from the schneider and start controlling from the AB.
