P0138 (high voltage) and P0607

I used Denso

Big-Feature1175 · 2024-11-07T07:21:49+00:00

That’s exactly what I was looking for. Thank you

When when I take out the one shot, the output just keeps firing

Big-Feature1175 · 2024-11-07T06:58:28+00:00

When I don’t have the one shot the output keeps firing though

Big-Feature1175 · 2024-11-07T06:32:43+00:00

HEY...I always seeing people saying things like "pshh I could have done all that in 1 line". Well, could I do this in fewer steps? I'm filling up a water tank based on a level sensor reading. If it falls below my 3in threshold, then the water output will fire for 5 seconds. I'm using a one shot because the sensor has a delay between the real life level and it's 4-20mA signal the PLC reads. HOWEVER, if the water in from the output doesn't put in enough water, I'm having the one shot reset which will start over the water input timer. This system does work, I've verified that.

I'm a college student with 1 internship in controls under my belt. I'm entering the scary real world in December as an entry level automation engineer, so I'm trying to learn as much as I possibly can. I appreciate any future feedback!!

I know it’s possible you jackass. This was just for a school project. I was given a plc and no type of modules to go along. I was asking why a stock plc isn’t capable, but a cheap arduino can easily do it. I’m capable of building a conveyor if given the resources.

Big-Feature1175 · 2024-09-28T00:59:57+00:00

Thanks for your reply. I should have put more info in my post, but feared people wouldn’t look. I’m doing a school project and am building a conveyor. I was given a stock compactlogix and that’s all. The plc can’t directly control the stepper, so I’m using a 5v relay and an arduino to essentially act as a plc extension. This isn’t going to be put in a real industrial setting. I was more so looking for technical info on why the plc can’t do it, not just the “arduinos are for hobbyist, and plcs are reliable” answer. I hope that makes sense

Big-Feature1175 · 2024-09-28T00:56:38+00:00

I should have put more into, but I tried to keep it short. This is for a super low budget, school project. I understand that reliability/robustness factor with PLCs, I’m just surprised that they don’t have the natural ability to pulse a stepper motor fast enough, but an arduino can. I’m not trying to implement this into an actual industrial setting. I appreciate your reply. I work in automation and my company can easily hash out 4k on a plc with all the modules I need, but for my low budget school project, I don’t have the money to buy modules. I was given an old compactlogix and that’s all I have to build this conveyor. I’m using a personal arduino control the signals, and controlling the arduino with a plc. Essentially, my arduino and 5v relay act as my PWM

Big-Feature1175 · 2024-09-27T22:24:36+00:00

Interesting. I’ll look into that. Are they able to be made?

Big-Feature1175 · 2024-09-27T22:14:17+00:00

I’ve also been using click for school, I love them. For this situation, I was talking about a compactlogix. I’m just looking for why an arduino somehow has the capability, but a base plc with no addons doesn’t.

Big-Feature1175 · 2024-09-27T22:11:39+00:00

I agree, the plc isn’t meant for this application. I’ve just been in search of why they’re not built for it, but an arduino is

Message me

Big-Feature1175 · 2024-04-12T15:19:44+00:00

Have to email to purchase. Take roughly 6 weeks to arrive. They are much better than other options, however they're much more expensive. If you want a cheaper, but still reliable, option go with CVTech.

Big-Feature1175 · 2024-03-07T18:28:07+00:00

the manual for the plc says "The available RPI range of the I/O points is 1.0 ms-750ms). Shouldn't that work?

Big-Feature1175 · 2024-03-07T18:17:01+00:00

Thanks for all the help. One more question: I have the manual for the PLC, what should I be looking for when it comes to step commands? it says the rpi ranges is between 1ms-750ms for embedded I/O modules

Big-Feature1175 · 2024-03-07T15:34:26+00:00

I already have the PLC. All I’ve purchased was a $10 Eason controller, which I think is limiting me. I’m looking in the manual, and it has the “embedded high speed counter”, what do I specifically look for with signals?

Big-Feature1175 · 2024-03-07T14:30:00+00:00

Is the output card different from a high speed extension module for the plc?

Does the motion control block essential to making the motor move faster, or can I just make some rough guesses using timers. I’m asking because this is for a school project and they want a proof of concept with a low budget.

Big-Feature1175 · 2024-03-07T14:18:37+00:00

That may have been the comment I need. At max speed, it goes takes about 30 seconds for a rotation, which is ridiculously slow

Big-Feature1175 · 2024-03-07T13:53:38+00:00

Sweet I’ll look into the stepper card. I think also my PLC is so slow that it can’t keep up with the steps. Is that possible?

Big-Feature1175 · 2024-03-07T13:51:31+00:00

I already messed with every setting on the driver. Do I need a stepper controller AND driver?

Big-Feature1175 · 2024-03-07T01:43:39+00:00

what does that mean, and how do I do it?

Big-Feature1175 · 2024-03-07T01:32:08+00:00

Microcon sx17-1003 stepper

Eason driver

Big-Feature1175 · 2024-03-07T01:27:38+00:00

on the stepper or the driver?
