Basically no, not regular do module, you have to use the CPU 'PTO' output. The regular do can not do high frequency, and it will cause your step motor has to run very slow or miss the speed command.

Thanks!

Welcome!

Thanks!

Thanks Bro, S7-1200 and S7-1500 safety most of cases are the same. you can use my videos for your S7-1500 programming

Thanks for watching!

Glad you enjoyed it

Enjoy

Glad you like

Welcome! Thanks for watching!

You need to define variables for all the individual axis.

@@electricalautomation thx for answer...Do you have experience with CNC control (G-Code interpreter) and with the interpolation of several axes?

Thanks!

Glad it was helpful!

Welcome!

S7-1200 (v4.x) can not use 'TO' to control S120. You can use 'GSD' method and EPOS telegram 111 to control S120.

Welcome Thanks very much!

The actual version is not the TIA Portal version, it is the HMI hardware revision as shown at 2:30. You need to find the HMI image revision correlated to your HMI hardware configuration revision.

You can change the settings for the 'target address and modbus address' to switch the communication target, OR , can multiple ModbusTCP Client FB and instance DBs to communicate with different target.

Not sure TwinCAT v2.x. You have to check kepserverEX manual

Thanks!

Oh Bro, Thanks a lot!

Thanks very much! Enjoy and hope the videos are helpful!

REAL has 4 bytes, so you can send a REAL as 2 words by using 2 registers

@@electricalautomation Thank you so much, I will try this

It works, but if there are many PLC as client to request data, I would recommend program a couple of 'server' by using different port.

Actually I don't need a client to request data. they only aim to send data to the server (PC) directly. Without having to communicate between another client

Thanks for your watching! Welcome!

The servo drive homing is a hard topic. If a RUclips channel is an organization or a company, homing how-how is their competence, in comparison, if a RUclips channel is a personal channel, it is really really hard to present this because it needs real servo and mechanical system, need many times to setup the equipement and explain the concepts behind but the view of the videos would be just hundreds per year. Therefore, finding a qualified video that thoroughly explained this homing topic would be rare. What I'd like to say is that, read the manual carefully and practice in your applications. Find the correlated homing scenarios matching your case (fix stop home, cam sensor homing, z-mark home, direct home, etc.) . Note that handling this knowledge is not easy and is free to get. However, manual documents and deep research studies are effective solutions.

My pleasure!

telegram 112? I recommend you read the siemens servo drive manual for your application, also review this ruclips.net/video/0ulu-sTMw9g/видео.htmlsi=L_6oSTDL_oA6awYS

Please review this ruclips.net/video/UlTYlOe1OeE/видео.htmlsi=1Dm2qfRfBtWcv_lL

@@electricalautomation in case for a sequence program and you might need to home your machine, how can you do that in reverse steps from any step in the program without causing crushes for example?

I believe they can, just take care your S7-1200 CPU revision >=4.2

Thanks a lot!

If you have time, please can you make videos about siemens G120 safety drives and encoder?

Thanks! my friend. For Siemens safety, please review the video [Siemens S120 #5] SINAMICS STO Safety Torque and SS1 Safe Stop vis Safety PLC ruclips.net/video/6HVA_4vNh5U/видео.html. or the video MS06I. [Siemens S210 #09] STO Safe Torque Off and SS1 Safe Stop ruclips.net/video/kWY6G71qO-8/видео.htmlsi=i_mWFB10P6-Yg3tN Also find the links under the video or find the drive safety videos from the playlist ruclips.net/p/PL762SfoJC-e8NbAUQ-H7a_TOdqrlBPCw4&si=kI3JlxEcN66X2NHJ.

Which is better for you to send a donate? RUclips or paypall?

@@tahsinaras-zp5yw Thanks! my friend, you are so generous. RUclips, thanks, or PayPal all works fine, whichever is easy for you. I am glad the videos could be helpful for you.

I think you need comprehensive understanding on the temp variable, interrupt, FC call. It is hard to describe and explain via word unless you could show your program and program structure. You could send me an email for your personal question coming with the donation for compensating the time and efforts for review your problem.

Thanks!

Thanks! Man, Glad the videos are useful for you

@@electricalautomation you are really the best. Can you also make a video about siemens safety drives for example G 120 safety drive? It is used so much in the industry.

Glad you like it

Thanks Bro

Welcome!

for using 2hz, you can use the m bits from the property of S7-1200/S7-1500, some frequency is auto generated
