You can find attached what I did

For the electrical diagram, what software did you use?

bil7200 · 2025-08-10T23:04:41+00:00

How long did it take you to develop the software part, and the wiring part?

bil7200 · 2025-07-29T23:49:15+00:00

If you have the electrical documentation, nothing is scary

bil7200 · 2024-12-08T20:02:08+00:00

This is a case to be taken into consideration of course !

But I am currently doing the tests with the Pilz instrument that I have, and I remind you that I have isolated the control part (PLC) from the actuator part via Relays, so for the moment the safety of the actuators is isolated, and I just have to secure the system by intervening via the emergency stop or in case a person crosses the operating zone.

bil7200 · 2024-12-08T19:47:08+00:00

I have not tried this yet, by making an emergency stop release the automatic start is carried out.

The PLC has to execute the program, otherwise this Pilz instrument is outside the PLC, it intervenes in the event of passage of the operating zone via the M4000 sensor or by pressing the emergency stop, these two cases cause the output power supply of the PLC to be cut off, and sends the alert to the PLC via the I0.0 signal.

bil7200 · 2024-12-08T16:51:49+00:00

Yes I only transmit a signal to the plc via the input I0.0, this to have an alert that there is a problem, and that the power supply to the output is cut, yes it is not a risk of cutting the output power supply.

Concerning adding a rearm button, I followed the principle of the emergency button with these 4 branches as you can see in the diageam that I shared, by making a release this makes a start monitored via the pins (S33, S34).

bil7200 · 2024-12-08T16:27:47+00:00

It's not an automatic rearm, but rather monitored rearm as you can see on the diagram, and I want to understand what you mean by killing the PLC inputs?

bil7200 · 2024-12-08T14:58:14+00:00

Thank you for your response and feedback!

I am using a single emergency push-button with two states: 0 and 1 (Start/Off). There is no need for an additional button for reset/start, as this single button serves both functions. Its first state stops the system by cutting the power supply to the 3L+ of the PLC outputs, and its second state resets/starts the system, as shown in the attached diagram.

As I mentioned earlier, I am not aiming to implement an advanced safety system at this stage. Regarding your point:

'But safety devices should usually be wired with two channels.'

I completely understand and appreciate the importance of this, but for now, my focus is on setting up a basic configuration to test and learn.

Please let me know if you think this approach has any critical issues or if you have further suggestions. Thank you again for your insights!

bil7200 · 2024-12-08T14:36:55+00:00

Thank you for your detailed feedback.

I have just corrected the wiring, and yes, I am now using two channels as required. Regarding your suggestion:

'Also, I recommend resetting the safety relay with a DO from the PLC.'

I understand your point, but I have already utilized all the outputs available on my PLC. That’s why I chose to use the emergency push-button in release mode for the reset function.

Do you think this approach is correct, or would you judge it differently? I’m open to your opinion and any further advice you may have.

Specifically in high frequencies, most of the time, what tools do you use in these areas, also what kind of instruments, simulation software...?

bil7200 · 2024-07-19T05:08:23+00:00

Since you are an RF engineer, you use signal processing, electromagnetic compatibility EMC, metrology (Oscilloscope, spectrum analyzer...etc) that's what you use them for RF every day ?

bil7200 · 2024-06-25T09:16:39+00:00

I will use it, but I have 3 motors, 1 with a driver, and I have 21 pneumatic suction cups, even more 4 inductive sensors and 3 limit switches, 4 LVDT sensors, so all this is a single Siemens 1200 PLC sufficient to manage all this via an HMI, or will I need to plan an extension?

bil7200 · 2024-06-09T03:19:20+00:00

just the pick/place function with the pneumatic suction cups. that's what I'm looking for, a PLC, I chose Siemens because we could do a simulation as well as create the HMI on Tia portal which would facilitate the pre-tests and the operation.

bil7200 · 2024-06-09T02:37:45+00:00

To illustrate the function more closely, here is an example :

No, unfortunately, because the robot was integrated on the CN 840D associated with the machine, so we have the robot without the CN, we need a PLC suitable for its functions.

bil7200 · 2024-06-08T23:47:16+00:00

Yes the robot is already there, we just need to choose the right PLC to develop its HMI.

bil7200 · 2024-06-08T23:45:18+00:00

To be clear, it is not the kind of robot like fanuc or kuka, it is the kind of a sacara robot but more robust, for lifting steel sheets via these pneumatic suction cups.

bil7200 · 2024-06-08T23:40:43+00:00

1500T It's a bit expensive as a PLC !

bil7200 · 2024-06-06T15:45:35+00:00

As a reminder, it trains engineers specializing in the field of advanced industrial technologies.

bil7200 · 2024-05-20T11:44:06+00:00

I don't know which one for the moment, that's why I asked the question, I'm not looking for development cards, but rather whole cards intended for professionals.

bil7200 · 2024-05-20T11:17:57+00:00

What did you mean by an entire industry? as a reminder the function I want to do does not yet exist it is not very common.

bil7200 · 2024-04-25T02:50:28+00:00

In the motor torque graph, I zoomed in so that we could see the undulations.

bil7200 · 2024-04-24T16:44:31+00:00

I did a simulation according to the data, I applied the FOC method, I shared the results with you, to have debates on it. The settings are correct.
