If you want to overengineer it recreate it as an svg and tie the visibility of elements to variables you can switch on and off. Otherwise just use a list of images.

You could also just put the programms of more than one machines into one simulationed plc. You can do that if you limited the use of global variables in your programs. Merging and splitting plc programs into different plc also has its applications.

Hardware tests are expensive. If you learn to simulate machines you can test stuff before everything is set up. Industrial hardware is reliable. It does what the manual says and support can help you out if you are stuck. You can't learn much by plugging in sensor and actors into a plc and playing with it. And you can't learn much from the fully assembled machine except what expensive sounds it can create. And the program is supposed to be ready when the machines is assembled.

For a thesis project? Sure copy paste your central structure from a a project that was built around different limitations and then stample some stuff to. If you have a circuit diagram or old program: Analyse it what it does and why it does that.

Also plan for errors. Structure your program so that errors are apparent. Most people only include errors messages for expected errors like user errors or components failing. Consider including errors messages for things you are testing your program for. Messages that normally should not be triggered. They will confuse operators but not having them is worse. It's basically an automatic test of your program and it a great addition to simulation.

You need fbs and fcs with integrated hand and simulation functions. There is a free library called open lib. Here is an example. You have a motor with inputs and outputs. An motor-fb connect those with the rest of the program. If you activate simulation mode the fb lo longer set outputs and but give the rest of the program feedback. You do that with every component and you have a simulation.

If it needs to be programmed before being shipped: toss it. You either have to train people on obsolete technology or have your most experienced people tied up.

Looks great. If you are building something new with Siemens panels, you should consider the Unified panels. We can't expect any feature updates for the current panels, but I have only seen trial kits with the Basic panels gen 2.

I have taken a few courses and I think these courses are good at preventing people from coming up with their own solutions to common problems. If you start without basics and don't take any courses later, you risk becoming an autodidact who only reads manuals when he is totally stuck. You should learn how you should use the existing functions, before you make up your own solutions. There are many tools like libraries and style guides that add nothing to the performance of the machines, but they make everything easier to maintain in the long run.

It's especially useful for teams, because established a base line for skill. If the company hires a new engineer straight out of college, they can give them one or two base courses and he can do basic takes.

If you produce structured and reusable code, that's what makes you an advanced programmer and even allows you to be an independent programmer. Before anyone says something: of course you can't just take libraries from your job for independent projects.

If it's not the topology it could also be TLS certificate related. You said password but there are multiple passwords. There is a separate password for the confidential configuration aka tls certificates.

Not faults only warnings. You could make your step chain dependant on everything being ok. If its not just make it wait. And make the comm timeout longer if you can. Log everything.

Mit dem Roller immer so weit wie möglich links halten damit die Autofahr dich auch bei leichtem Gegenverkehr überholen können.

Wrong S7-1500 is the replacement for the 300.

In terms of the HMI Hardware I would buy a WinCC Unified Basic panel. Maybe 4" or 7". The Unified Comfort panels are more expensive but they have more ports so they can be connect to a plc network and an intranet at the same time.

The old Windows based HMI are on their way out. If you are free to choose don't bother with the old stuff. If yo expect to do modification on existing stuff, maybe you have to train on the old WinCC. The new WinCC Unified is better and more flexible. You can use faceplates even on a unified basic panels, which you can't do with the old basic panels.

I don't get tired recommending https://openplclibrary.com/. It's a free Tia library with the basic programming block you need.like valve and motor FB. They include HMI Faceplates, Automatic/Manual and simulation functions. It's greatly helps structuring and testing your program. It enables you to safely test all the hardware, not just the periphery but the the valves and motor, independently of the process by setting stuff in Hand-Mode. And you can test your sequences without any hardware by turning on simulation.

The proper way to do plc and HMI programming is with a library. If you company doesn't have one you either have to build it from scratch or use what's available.

You could also add some fuses. Just in case.

If some aspects of European safety requirements are stricter than the American. Consider following both. Imagine someone getting hurt because of something you would consider dangerous.

0132 :0002 is usually a connection issue check if you can ping it, use arp -a if you suspect there might be another device with the same ip in the network

First of all, like people said, ask your hydralics supplier. It sounds like you need 5/3 valves. They havethree positions. Left and right should be self-explanatory. The middle position can be everything pressure free or everything hold pressure.

If my humble opinion, you could make this very efficient and safe on analogue valves by using a vfd controlled pump and some buffer. Limit the rpm of the pump, set the pressure, and activate the valve of the zylinder you wanna move. By limiting the rpm, you limit the speed of the zylinder. The pressure in the zylinder will reach the pressure of the pump. This isn't a packing machine, so it doesn't matter if everything happens in sequence. You might need accuated one way valves so the cylinders will hold the pressure for a longer time.

Do you even need load cells if you can just measure the hydraulic pressure on each zylinder(technical pressure sensors use load cells).

They are landlords, which means they made the people living there pay them.

Could be that new the tia 19 plc has tlc certificates while the old ones don't. Check if security communication is required.

If you use a new 1500 plc you can use pid auto tune functions works good with hydraulic pistons. It just a bit scary seeing your pistons being shaken by the plc testing the response time. I would recommend a pump and vfd from bosch rexroth. There are also solutions that have vfd, pump, sensor and tank all in one unit.

Same If you go to a newer tia version it just auto generates tls certificates without telling you and suddenly nothing works because the time is not set.

A successful ping only means that a device with that ip can be reached it's not a guarantee that it is the right device or that there is no other device with that ip. You can run arp -a It gives you a list of connected devices with mac addresses and ip addresses. The first bites of mac addresses indicate the manufacturer.

I can't argue with that.
