Hello. Congrats for the video. But can you show how to configure everything when using TLS ? like port 8884. I am interested in how to configure certificates in tia portal so the client will work on a plc with the highest security level possible. Thanks
Great, Thanks for Details, I tried for libraries but i couldn't find it, is it possible to share this project program? that would be highly appreciated, thanks in advance,
The project is still available here: support.industry.siemens.com/cs/document/109748872/ The libraries are now a part of LCom package: support.industry.siemens.com/cs/document/109780503/
@AutomationStation Hi sir i have connect local server with broker successfully but cant see siemens PLC in mqtt explorer.And also in Lmqtt FB different library other than u only see LMQTT_typeConnParam this type in Data type.when i enable LMQTT client FB but it shows error code 16#8730 please help me
Thanks for taking the time to do this tutorial. I found it very helpful. Have you had any success connecting directly to AWS IoT? The block seems to accept X.509 certificates.
Hello there, i have a question cause our customer recently asked us to not function as a client but be a server instead to them. Is that possible with this method?
I'm afraid a PLC cannot be an MQTT broker which is what you're after in this instance. I would suggest looking into setting up a broker on another device - maybe an Industrial Edge device or something like an IoT 2050 and then your PLC would be publishing/subscribing to it.
is it possible to publish data from your function block to the brocker while u receiving message from antoher topic on to your sps client at the same time ?
Good night, all right? Can you make the MQTT block available for download on any platform other than SIEMENS? because now they no longer provide only the block without configurations, it already comes with some. I'm doing TCC and needed it without any configuration, like yours.
Hello sir! I have watched your video for couple of times but still having problem :( Is it possible for you to share your project file? Thank you for your time and effort 🙏🏻
This video was helpful. Have you worked to send series of data written in a DB(I have sensor values, and other field devices values in the Data blocks) through MQTT instead of just sending messages??
Hi. Several days i tried to establish connection according to your video, but something goes wrong. I cannot connect broker with my local ip of my PC. It says immediately Disconnected from server. In your example ip ...42 - is it your PC ip address? If i use localhost like in your previous video - broker starts, but PLC can not reach. When i start ENABLE bit i have status 7002 and BUSY and VALID (siemens updated library and FB) but after 20 sec it back error . I opened port 1883 on my pc but cannot test it via command telnet - it turn error. Any suggestion pls.
Have you had a deeper look into the TCON blocks status? The IP you provide here needs to be the IP of the broker. Have you confirmed you can access your broker? I would try with another laptop running an MQTT client.
Hi, Thanks for the video! It looks like the lmqtt library for V16 is no longer on the Siemens website. The only options I have is to download the documentation or the example project. Do you know where I can download the library?
Hi AutomationStation, I have succesfully setup Mosquitto broker. Now I have this IoT Device(thermal temperature scanner) that when I setup it ask me two things: 1.) Url (I put here the ip address of the mosquitto broker and port). 2.) Company Id (Im not sure what to enter here. Should I enter here the service name of the Mosquitto broker which is mosquitto?) Im not sure about the no. 2. I still cannot connect the device to mosquitto broker. I hope you can enlighten me . Thanks a lot for this tutorial.
I have not come across Company ID before, but perhaps it could be referring to Client ID. According to the MQTT spec each Client should make itself known to the Broker using a unique Client ID. Perhaps try using a unique reference in this value and see if that works.
Hi AutomationStation it is wonderful video. I have a question for the program. I did same thing but when I push MQTT enable and it is value true but Mqttestablished is not true also tcpestablished is not true they didn't change Can you help me?
@@AutomationStation Ive been trying for a couple days and no luck. Any ideas? there are only a few parameters needed to make the connection. HW, Conn ID, address. unless there is something else i am missing.
Hello, great explanation. But i'm getting a protocol error and it disconnects me from the broker. Does that have something to do with certificates? I didn't set a username/password.
Well if you're not using username and password make sure that your broker accepts that. As long as you're not using TLS the certificates shouldn't matter
Thanks for this great video, very helpful to a MQTT newbie like me. The problem I have is that the newer LMQTT blocks on siemens website through the link have now changed and the datatype required is no longer a WSTRING and now requires an array of bytes. I am desperatly trying to send REAL datatypes as the message and cannot find any information how I can achieve this. Any help would be greatly appreciated. Gary
Hi Gary, I would use S_CONV to convert my Real to a String and then a Strg_TO_Chars to output that String to the Array of Chars (you can feed it straight to the Array of Bytes that the new block requires as publishMsgPayload as in the memory Chars are represented as their ASCII codes so no conversion needed here). Strg_TO_Chars will also output you Cnt which will be your publishMsgLen. The pChars of Strg_TO_Chars tells the block from which element of the array to start writing the data so I'd go with 0 there. Now the above behaves slightly different depending whether you use it in SCL or LAD. In LAD it will add spaces in front of the String but it should still be fine on the broker side. If you'd like more control over the output of the Real to String conversion you can use STRG_VAL. Hope that helps I might make a new video as looking through the block docs now it did change a fair bit although the principles stay the same.
@@AutomationStation Thank you for your help and advice. Sorry, for the delay, I have only just seen it as Ive started working on this project again. Your video really helps but the block library that your video is based on seems much easier than the new block as the older block you could just enter a string to send where the new block only sends bytes. im stuck at the moment with an error code of 8C05 on the comm settings so trying to sort this now :-) Really appreciate your help, thank you
Hi, thank you for the good videos. can I publish from the same laptop that I used as a broker? or should the broker and publisher be on separate devices??
Hi Igor, from my experience I'd say it's not possible I'm afraid. Didn't have time to look into why though. If you have some time you could open the block up and see if completely stripping security options from the code itself would help as in general PLC Sim Advanced supports Open User Communication but doesn't support the security options and certificates.

Dear Mihow thanks for the wonderful video.

Status error 16#8601. MQTT explorer says that is disconnected from server ? I would be grateful if you could help me . Thanks in advance
Don't have documentation handy at the moment but I'd suggest going into the block to see what 8601 means exactly. If it's a status inherited from one of the internal functions then you will be able to find the exact meaning in the documentation. Is it connecting for a moment and then disconnecting or not connecting at all? Lot of people reported strange behavior with latest versions of Mosquitto - might be worth checking an older one. You mention Explorer saying it's disconnected - is it explorer that doesn't connect or are you checking system topics to see if the PLC is connecting? If the explorer isn't connecting check my other video on how to setup the broker and what to look out for. Only if Explorer connects go on and try to connect from your PLC
I have installed mosquito as you demonstrated in your other video and mqtt explorer and tested it and is working fine, so mosquito and explorer are running. The library and consequently the FB Client that i am using has the below outputs : valid busy done error etc When i am enabling the FB, outputs "busy" and "valid" become TRUE for about 15 seconds and then error becomes TRUE and "valid" and "busy" become FALSE.

Hi, could you give me an advice regarding the following i watched the other video and I established the connection with (localhost) and some other laptops on the network. So, for me mosquitto broker is ok I can't ping my broker I skipped using the password step and I removed it from the program I am using localPort=0 and mqttPort=1883 and hwIdentifier=64 when the block is enabled through (enable bit), I got [busy] bit True for a while then it becomes false, no errors were detected. Just to be 100% sure there is no configuration errors from my side, Could you share the project files? Many Thanks.
You can find a demo project on the Siemens support site: support.industry.siemens.com/cs/document/109748872/ In regards to pinging, we're of course pinging the machine on which the broker is running. If it's a Windows machine I would first try disabling the firewall and only then check if you can actually ping. Having said that, if you can connect with a mosquitto client like MQTT Explorer but you can't ping I wouldn't worry about it too much and would most definitely say it will be the firewall blocking the ping itself. I'd make sure to add some traps so that you most definitely capture any ERROR/STATUS codes. The ports and HW Identifier look ok for S7-1500 and default settings on the broker.
