TIA Portal: IO-Devices / PLC-PLC Communication

One way of PLC-PLC Communication.
Very easy to send Outputs from PLC to PLC.
Works for:
S7-1500: All
S7-1200: From Firmware Version 4.0
S7-300 From Firmware 3.0 (Only when having PN)

Great videos indeed. I've seen your all videos of TIA portal and all those gave me clear concept of my confusions. Thanks a lot for sharing your knowledge via great video tutorials.

You watched ALL the videos? Not bad, that's more than 30h of watchtime!😄

I like the way that you explained things, simple and easy to understand. Keep going, produce more and more such a topic. I think, one day you will hit a million view, that's something you would afford :-).

This vedio series are very valuable. Thank you for this. Further, please do a vedio for profibus communication between PLC to PLC and field devices such as VFD, encoders.

[@mlu5653]

A nice fact is that only one of the PLCs needs to support and have the possibility to select operation mode - I-device. The other only need to match the area set-up in the other one.

[@HIRENECTECH]

I thank you for putting efforts in making these very useful videos. I would like to know, if this communication only works between PLCs ? and how is it different than the one using GSDML file.

[@shafips5413]

Great videos.. Am very thankful to you ...

[@whitemonkey7932]

Thanks...lots of conflicting info and I'd like to get the software finished and hardware config ready - It seemed that it was necessary to use PUT/GET which didn't seem logical when the config was already carried out at hardware level. I'd guess that whilst not very elegant, there would be no problem in copying Mbits or extracts from DB's with a move to the output area, to be translated again at the coordinating PLC. Once again thanks...

[@williamhernandez7894]

Based on profinet, I think that in the box of tia portal for a controller, this should say I-DEVICE instead of IO-DEVICE. Thanks for sharing your knowledge.

Hello, can i use this method to establish communication between two PLC which have different programs?

[@fonso_8416]

Hi Hegamurl! Very good job indeed! Sorry, as far as I understood the memory space that we need to save in IO Controller is 1 byte? I mean when you press switch I0.0 in IO Device that means a full byte will be true I 1 in IO Controller: An other question would be.. Could I connect more than 2 CPUS, I mean, when press I0.0 in PLC 1, then send a signal to PLC 2 and PLC3? I am confused sorry.. Thanks!

[@fash9340]

Thank you that was very good. Can we automate the process by setting the IP addresses in the program and creating a master PLC and slave PLCs?

Hi Phil: how to assign multiple controller from a single IO device (PLC signal from)? seems you can not assign one controller. Assume I need to send one signal to two or more PLCs.

[@Matze221284]

Hi, I'd like to run two machines simultaneously for redundancy. Each PLC should run independently but in any case of failure, the other one shall take over. So, If a failure occurs I'll transmit one bit from one PLC to the other. This should work in both directions (Bidirectional). Is this the recommended way to do the communication, or would it be better to do it with the put command? Thank you in advance.

[@aamirawan7998]

You gave the address i0 for the IO controller (receiving PLC) in the operating mode which means when you turn on the button i0.0 should have turned on in the IO controller but rather I1.0 turned on in the simulation of the controller (receiving PLC). I know that you set i1.0 address to physically connect the button to the I-device (sending PLC) but you set i0 for the IO controller but still i1 turned on for the IO controller as well. Why?

[@freedom_is_responsibility]

Hi, Thank you for your effort and good sense of humor:). I have a question, is it possible to test PLC-PLC communication using PLCSIM?

You would need PLCSIM Advanced for this. It MIGHT also work with a tool called "netToPLCSim"... but I have never tested it with this

[@kinstella6211]

hey Hegamurl! I need your help that I have a question about PLC communication and sequential programming. I hope I could describe it clearly here: I have one project with two PLCs(two S7-1200). I follow you to use I-device to set PLC2 as I-device and PLC1 as IO controller. I set two communication areas: Q100 from PLC2 to I100 in PLC1; Q100 from PLC1 to I100 in PLC2. PLC2 has one sequential program in its step 2 and step 4, it gives the task to PLC1 for one assignment (axis1 move absolute). The program should run as automatic cycle. But in reality, it ran several cycles and stopped. The cycle time was random. I am really getting stuck. I know it is difficult to describe the problem and it may confuse you. I just want to have a try to see if I am lucky enough to get some tips. Thank you!

Can I link 2 CPUS, in the same network address range but in 2 separate TIA PROJECTS, over profinet? Maybe using OPCUA? Thanks for the great videos i look forward to each day's upload.

[@hegamurl7434]

Of course you can! OPC UA would be a solution, but not my preferred one (the biggest advantage of it is that you can go across different networking types). As both CPU's are using PROFINET I would use "TSEND_C" and "TRCV_C"... with those you can communicate with basically any Ethernet device, as it uses standardized ethernet packages. One of my next videos will be about that!

#any thoughts?

[@saeed2tube]

Hi If we have analog signal i think we should use 2byte for addressing. If im right.

[@hegamurl7434]

Yes, correct! The area for sending is flexible, but an analog value takes one word/ two byte. Anyhow, it would be better to send TWO WORD rather then two byte, as each analog input uses two word (even though the value is transformed to INT which is one word). I don't know what it uses the 2nd word for, but better be safe than sorry 😅

[@erandepira]

In this case he had a boolean type for the pushbutton, which block did you use in programming for a doubleword type of the analog sensor to make it an output?

[@felixmutandi4753]

i need to know if you dont have the PLC physicaly it s possible to see these MAC adress?

[@hegamurl7434]

As every physical PLC has a different PLC address it's impossible to know it without having the real device. If you are connected in a network with the device it's possible to read it through the diagnostics... but that also means you have access (through the network) to the real PLC

This method only for digital I/Q or we can use it in analog signals

Yes, you can. It just sends bytes of information and it can be anything. In this video we have only one byte sent, but you can send much more. Ex. define your Address in IO controller " I 1000...1099" and I-device respectively "Q 1000...1099" and you can send 100 bytes in memory area 1000 - 1099.

Hi versterker33! If you are using "PLCSIM" it won't work, because the simulation does not simulate the "hardware" part of the PLC, which networking belongs to. To simulate such behaviour, you would need "PLCSIM Advanced", which "emulates" the hardware
