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.
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?
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.
I add output Q0.6 in hardware interrupt OB40 (s7 300 PLC). As per your video after rising edge my output Q0.6 continuously on. Output Q0.6 is connected with input rising edge I124.0. How can I off my output Q0.6 ??
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?
Sometime My plant PLC is giving following error. So can you give me solution . Diagnostic Buffer I/O read access error.(I address 15004) in FC 15014. I already checked in FC and found iOS has been called only in once. From last one year system is running ok. But last two days error has been come. Because of this error some time IM module has been communication failure. Because of that related section of plant has been stopped. But again it will be reconnect with in milisecond.
Hi, i need help, there are some way to protect the PLC against mres? I could Solve on a PLC 1500 with display protection, i did a password, but i cant do that with plc 300 and the some people in my work reset the memory without reasson and it's easier to them because push the swich and delete all configurations of daba blocks. If you can help me i'ld appreciate it
Hi Hegemurl! As fas as I understand, I can creat OB40 for stop emergency and I0.0 as input channel, and I connect my EmergencyStop button to I0.0. Every time I push the button, programe in OB1 will stop. Is that correct?
Hi Ntombo! I have never used the "DRUM" sequencing block. But it looks quite interesting, I might look into it and make an example at some point. The problem I've got in this block is that TIA Portal lists it in "Legacy", which means it is an old type of block/programming that is not used anymore these days and/or there is a better alternative for it. I try to avoid those "Legacy" blocks as much as possible... but it still looks interesting, so I might look into it!
What happens if the hardware interrupt is being in loop processed ... ?? i mean how to ensure that the main OB are processed after going in hardware interrupt ??
Can we create Hardware Interrupt with basic module? for example if we can add a function and give this fuction priority 16 or more. or if there is any other way to create Hardware Interrupt with basic module Thanks
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.
@@hegamurl7434Thanks for the reply!! I was wondering where can we use arrays and structures, how will that be beneficial? I actually couldn't relate it to any industrial use as such, coz if we talk abt PLC data type then that is nothing but a structure in itself then how structure and PLC data type are different from each other? I'm pretty confused here.
@@bhagyashreezaware5314 So looking at the direction of "composite data types", got you! Especially UDT's (User defined data types) are pretty important. I'll put it on my list of things to talk about!
@@hegamurl7434 could you make a video of how analog signals are recieved by AI modules? And how they values are recieved ( i mean their datatypes is it double word or byte)
Thanks for this video but whats about electronical hand wheel with A / B signals , it's usefull to use OB40? I like to detect the turn direction with the interuppt signal.
Thanks for your great videos, I really appreciate them... @Hegamurl Just a question. I understand that the hardware interrupt can take place at any time and does not depend on the input's value in the main process image stored every time before the OB1 is executed, but on the current actual state of it. If I want to use that very input in the OB40, do I need to use another process partition image for that input, in order to have the real value of it during the execution?
Excellent. Did you know that there are no educational videos on this topic? Like you, I love automation and gaming. And getting to know you is very appealing to me. I follow your training. Good luck
I have selected ONE input channel (Channel 0, which in this case is I0.0) for rising edge detection. The interrupt OB will only be executed when detecting a rising edge on that input, and won't be called on all other inputs. If you want to select I0.1 instead of I0.0, you would have to select input channel 1. You can do that for all input channels seperately... I quickly show it at 7:18 in the video. If two/more channel should detect the edge, then you can just assign the same OB to multiple channels
Hi Alireza! Good Idea! Unfortunately I currently do not have private access to another PLC/IO Device (for shared devices I would need a third one...). I will try to get my hands on one and make a video on it, but it might take some time
Hi, great videos! Could you make an video where you explain a bigger picture/ overview? Maybe a little background of plc, what are the things one should be able to do for a expert level so on :) maybe too boring to do. Or can write you mail? Br
Best PLC channel on youtube!!!!
As always: thanks!
I confirm for 1200 PLC , they have hardware interrupts lined to inputs on PLC itself .
Thank you so much for sharing these videos! Lots of love and support from Australia!
Nice explanation, easy to understand, thanks for your great work
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.
Great! Happy it helped!
I like your way of explaining the things
you truely deserve the best. Thanks a lot

You use data block for making a static variable, can we use local variables for counting the interrupts ?
thanks for your great work
Great job dear! Thanks a lot.
What should I do if I use encoder ? Case with encoder card and case with fast inputs ? Thank you.
Then is call the ob40 When you put 24v on the DI... Did I understand correctly?

I use I0.0 as an interrupt input but also as an ordinary input elsewhere in the program. Is that allowed?

No it will stay on loop and wreck your program. hardware interrupts are not meant for HSC. You can easilly program that in like a single rung
