Hey Frederico! Thank you for your nice words. The hardware and network configuration you see in this video belongs to an automation system we deigned for a refinery so all see here is technically correct. If you see four IMs in the NetPro instead of tow it means you have not used the “Insert Redundant” option while copying the IMs. I have made you some screenshots to show how to do that in 3 simple steps.

Why you dont switch terminator ON to A2B2 profibus network on your Repeater???

[@realpars]

As the Repeater is in the middle of this network you should not turn its terminators ON.

[@user-fg3yy3tr7j]

@@realpars its wrong, you must turn terminator ON. Picture from SIEMENS manual: i65.tinypic.com/200vjuf.jpg

[@totostyle1]

Is the repeater necessary to make the link between the 2 CPUs and the HMI Panel? Can't we use the same way as done between the CPU-A IM-A-1 IM-A-2 ?

[@realpars]

Redouane KECHIDA We need to connect two CPUs to a HMI panel that only has one input! So we do need to use the repeater. It works like a adapter here.

[@realpars]

Thank you, Mahmoud!

[@ricardogarcia3900]

Great video. Congrats. One cuestion. Could I connect the three profibus connector in cascade ? (OUT 3 -> IN 2 / OUT 2 -> IN 1). Thanks in advance, for your aswer.

[@realpars]

Yes, of course. That is the normal way that Profibus is connected in a segment (daisy-chained)when you have multiple devices. The Profibus connectors shown in the video have an IN terminal and an OUT terminal. In your example, device 3 and device 1 only have one connection, so you would enable the segment terminator (via slide switch) at those connectors.

[@phoneoceansupport4737]

Is this repeater works for communication also? Or we can use scalance switch !! We are making same system with S7 400 ! Can u explain working of repeater !

[@CM-oy2kd]

What's the name off the module that's in the middle on the top rack

[@realpars]

That an RS485 Repeater. We simply use that to connect the two CPUs to the HMI.

[@scofield807]

Thanks for the video, it's very well explained. I have a question: what's is the meaning of SWR there and how the cable is connected to the connector (in input or output)?

[@realpars]

SWR = software redundancy. This cable is a ProfiBus network cable that connects to a communication interface (CP) card on PLC A and to a CP card on PLC B.

[@scofield807]

​@@realpars I understand that, but do I have to connect the cable on both ends to the input port of the DB9 profibus connector or to the output port?

[@felipegomeslandim4492]

Great explanation. It makes me feel more confident in my new project using PLC by siemens. So...I'd like to know how can i do to communicate my cpu with an ASI Module? Is it easy? By the way, thanks for help me! Brasil

[@realpars]

Felipe Gomes Landim Thanks for the input Felipe! We've worked with ASI modules in some projects and we didn't have much problems for configuration. Boa sorte com isso! :)

[@balajovidiu9699]

Hi there. Do you by any chance know how to make an S7-300 read a code using SR-751 (Keyence) and store the string into a block or variable so that I would be able to read a bock of data (including this code) from another program by IP? I want to learn lots of PLC but this is my 1st project (individual) and I saw you have lots of PLC knowledge :)

[@nsnnsn5445]

iam a beginner in this field , does there any change in ladder diagram for each plc in redundancy ?

Both PLC programs are the same but some of the addresses are different.

Helll Realpars What if there are two rs repeaters which each one is connected to different Profibus network, then one out of the DP is connected to the other one , then looped through to be connected to HMI How set that up in HW configuration?

[@realpars]

Hi Saed, Thank you for your question! The Siemens system in the network configuration has embedded software rules it follows, and when you compile the software for errors, it will notify you and gives you some solutions to help solve the errors. But what you are asking, I believe, is not possible. Here is a link for your review on the possible redundancy possibilities with Siemens PLC. support.industry.siemens.com/cs/document/1137637/simatic-s7-300-s7-400-software-redundancy-for-simatic-s7?dti=0&lc=en-US Hope this helps!

[@saedalhabbashi2790]

Thank you so much RealPars Let me put my question clearer. Two CPU s71500 type Each one of the them is connected to the same a Redundant IM ( only one i/o Rack) Ok The two OUT DP signalS from the IM are connected as IN signal to two RS repeaters , namely repeater A and B The out of the repeater A is connected to the out of repeater B then looped to the HMI from Repeater B . How to set this configuration in HW configuration. I am so grateful for your response in advance.

[@linggadewangkara1168]

Hello friends, thank you for explaining the PROFIBUS network system. as a newbie, i have a problem to adding new IM200M CPU module with Digital output module as a third DP Slave from SIEMENS S7-300 CPU315-2 DP as a DP Master using PROFIBUS DP Comm Protocol. Assume there is a setting on HW config about maximum DP Slave device that can be possible added in this CPU. so the present condition is my CPU315-2 DP just possible to connect with maximum 2 DP Slave device. Can anyone help me so i can add more than 2 DP Slave device? regards

[@realpars]

I assume you meant ET200M, not IM200M. You should be able to add as many Profibus DP modules as is allowed by the protocol (126 nodes per segment). I suspect you are not setting up your network configuration properly. Why do you say you cannot add another DP slave device? Did you get an error message during the hardware configuration? Are your slaves all set to unique node numbers between 2 and 126?

[@akashkarmakar3803]

Hi, May I know from HMI where it's connected to?

[@realpars]

The HMI in the video is connected to the MPI network, a network type that uses the same connector as the Profibus network but is connected to an MPI port instead of a Profibus port. MPI = Multipoint interface, and was the original communication interface introduced by Siemens. It is well-suited for connections to HMI panels and other peripherals in an S7-300 architecture.

[@akashkarmakar3803]

@@realpars sir, you guys used to provide us fantastic videos....highly grateful .. Actually my question should have been little more precise. From repeater output to hmi via mpi network, but I could see two cable in hmi ....where that second one is directed?

[@akashkarmakar3803]

@@realpars sir, looking for the answer.?

[@bitebonumbere1426]

What's a CP module? And what's the meaning of SWR?

[@realpars]

CP =- communication processor. A CP card adds a communication port to the CPU, such as an additional ProfibusDP port, as in this video. SWR = software redundancy. This is software-driven redundancy strategy that uses peer-to-peer communication between two CPUs to provide a backup in case the primary CPU (CPU_A) fails.

[@noemimaqueda164]

I have seen your 19 free videos, and I have a question. In the video 14th, named as "PLC Inteface Module"... You said that we need an IM next to the CPU in the first rack, and another IM in the second rack. Here we don't have an IM next to the CPU, why we don't need it in this case?

[@realpars]

Hi Noemí Maqueda , using IM varies based on the project and application. For the project that you see in this video, we're using Profibus-DP network and connecting the DP port on the CPU directly to the IM on the next rack.

[@noemimaqueda164]

realpars.vhx.tv/plc-hardware/videos/35-interface-module-final-1 this is the 14h video I was talking about, there you used an IM next to the CPU, even when the DP port was free... Why? By the way, I love all your videos, it has helped me a lot, they're excellent! Thank you so much.

[@realpars]

Noemi, Glad to hear your positive feedback. As I stated before, there are different projects. Depending on your project, sometimes you need to add an interface module next to the CPU and sometimes you need to make use of the port that you have on the CPU. In this video, we have an S7-300 redundant system. That's why we use a diffrent configuration.

Ok, thanks for your answers and time :-)
