Thank you so much for sharing these videos! Lots of love and support from Australia!

I confirm for 1200 PLC, they have hardware interrupts lined to inputs on PLC itself .

[sarahlabidi]

Nice explanation, easy to understand, thanks for your great work

[arkri]

Same here, I did it on a S7-1200, Tia v16. Thanks a lot for your help, gait job, keep it up. I will be recommending you to my fellow programmers.

[plcxautomation]

I like your way of explaining the things

[MBMech]

you truely deserve the best. Thanks a lot

[pardeepchhikara]

Thank you very much.
Your tutorials are very helpful.

10:49 "be carefull... high frequency".
Not clear, so what a difference between BA DI module and HF DI module if
first one is not able to react at high frequency and usage of second one also limited by high frequency.
For example to count 6000 rpm, what module is suitable for that purpose?
6000/60 = 100 Hz pulsation frame we have.

thaks for your effort to share knowledge with us

I was wondering if you are still making TIA Portal content? I haven't seen any new ones.

Good day, actually, i do not understood, when we need to use these funktion? please tell any example.

[JinsonKurianVJames]

Nice video. Thank you.
Can you make a video to download program in remote plc with router.

[ntombomusimubianda]

Nice video...Do you have one with an example using a "DRUM'' block

Hey, you are doing amazing work. It would be great if you could do a video on application example of complex data types. There is no proper info available on it other than the standard declaration of variables.

[bluebug]

Hi there, it would have been good to explain how to handle all the different points of that card independently. Say you have a different function on all your 16 points, how are used the local variables of OB40: LADDR, IChannel, EventType, PointAddr to handle the correct input address and discern rising from falling edge. Otherwise people will have the reflex of creating a new OB for each point :D (I had two colleagues do that already! instead of doing the proper handling in the OB). Also to note: if you have older hardware and remote IOs (S7-300, ET200SP) then you have to use the old version of the OB40 which had local address like OB40_EV_CLASS, OB40_MDL_ADDR, OB40_POINT_ADDR, and was much less intuitive.

You use data block for making a static variable, can we use local variables for counting the interrupts ?
thanks for your great work

I have tried test this on PLCsim and it doesn't seem to work. But I haven't tried it on the real PLC yet. just want to ask that it doesn't work in the SIM right?

[Ashlvvy_.x]

I have a problem on plc 414 using this hardware interupt OB40 when ever one iinput is activated the cpu goes to stop mode and internal fault red is on. My question is how to resolve this problem?

[hectorrocafort]

Then is call the ob40 When you put 24v on the DI... Did I understand correctly?

Hello Sir, Can you make a Video of Siwarex wp231 Programming, explaining data Record settings?
