@@safaritooncesrv7946 thanls for watching. LOGO and industrial PLCs don't natively suppory Zigbee. if you want to connect a Zignee device to LOGO, you will need a middle software. You may use Homeassistant as the middle software and I have a video to showcase this application. You could also use Zignee2Mqtt to convert Zigbee to MQTT which is understandable for LOGO. I'm crrating a whole tutorial series for LOGO. The first video is already available. Make sire you follow that if you want to learn Modbus, RS485, etc. In LOGO!

@郑凯瑟琳 thanks for watching. If you want to send multiple data at the exact same time, you need to add multiple FB instances. Otherwise, you may change the data variables and send them in a periodic way. Also, it's easier to send data in diffefent format and data types with OPC UA PubSub over MQTT instead of flat MQTT.

@@Bermsompochwutiya hello, PLCs including s7-1200 don't have a built-on wifi. You need external wifi client modulea if you need wifi connectivity.

@@blociot thank you ,sir

@@Ind4.0 hope you find this tutorial helpful to start using it 🙏

@@roberthollingworth906 thanks for watching Rob

@@AmbarBWeberG hi. LOGO has Ethernet port not wifi. For security reasons, industrial controllers normally don't have an integrated wifi module. But if wifi connectivity is needed, a separate wifi module can be used and LOGO can connect to the mentioned module via cable. There are many of them in the market. Siemens also has variety of Wifi client modules

@@Indrajithmeghanada you don't need any GND or power to activate the relay output. If you command to set Q1 (relay type), the relay will be switch ON.

Agreed. 4" is too small and should be avoided if there are several object on the screen as it gets cluttered quickly. But it has its own use case for some projects.

@@florianosabatini4016 unfortunately, not possible. MQTT is available as of V8.4 hardware

Thanks for watching.

Awesome! Hipe you enjoy using your new LOGO. Let me know if you come up with any questions on the way

@@kacperkubacki2951 absolutely. Each client block needs to have a unique ID and they can work independently.

@@TanapongPonghanat hi. One of the main reasosn that the communication doesn't work is the date and time in PLC and HMI are not properly set. Please double check the time on both sides.

@blociot Thank you. After I setting the time for both PLC and HMI, now it works.

Hi, Do you have any ET200MP added to your project or tou have a 1513 and a S210 only?

Aah I see this is also returned in your case.... something else might be going on

Yeah, all seems to be fine. What I am guessing is that the program that is active overrides the value change. I have M7 connected to the power bar (ladder diagram) and I have a break contact that I want to control. I do not see a way to control M7 without having the coil connected to some output. Any clues how to go about it?

@seattledutch so I undsrstand well, you want to control M7 over MQTT and locally from the logic? If not, you don't need to connect M7 to any coil. I would write my logic so that a dedicated memory area is allocated to data receiving from MQTT and use them in parallel or series in my logic. I'm curious what logic are you trying to implement?

@ correct, I want to add a break-contact switch so I can disable a certain circuit. However my ladder diagram doesn’t allow me to add a M7 switch unless I add an M7 coil.

​@@blociot I finally solved it. I used a network input block and communicate the state through VM, and set it through MQTT. The switch is then used to disable a circuit by putting it in line with a health status marker as a NC which is opened when the kill switch is set to 1.

You can easily do it by changing the tags containing the topics name in a loop or in a sequence. Are they all in the same broker?

Hi@@kacperkubacki2951 . Unfortunately, PLCSim only supports local communications. For external communications, you can use PLCSim advanced which requires a license.

Greta to hear the tutorial was useful. I didn't understand what do you mean by "when you change the first one...". Would you be able to explain more? If you want to access two analog inputs for example, first, you need to make sure the inputs are included in the transfer data area in the LOGO software. Once they are added, their value will be published to the topic as an JSON element. Here is an example, how you can access two analog inputs as two different MQTT sensors in HA: - name: LOGO Analog Input 1 state_topic: "logo/pub" value_template: "{{ value_json['state']['reported']['AI1']['value'][0] }}" - name: LOGO Analog Input 2 state_topic: "logo/pub" value_template: "{{ value_json['state']['reported']['AI2']['value'][0] }}" From the error message, it looks like I2 doesn't exists in your JSON payload that LOGO is publishing to your broker.

Do you mean connecting a S7 PLC to a LOGO over MQTT, or using MQTT in LOGO v8.4? You can certainly use MQTT in LOGO v8.4. We have a few videos on how to do it on the channel. Here is one of them: ruclips.net/video/0joaGr4Ssio/видео.htmlsi=WbXyX2nnSu3z2s7T If you need to connect a S7 PLC to a LOGO over MQTT, you need to do some data handling at the broker side because both S7 PLCs and LOGO require a topic payload in a certain format. So you can't directly publish a payload to a topic and receive it from an S7 PLC and vice versa. But with data manipulation at the broker, you can.

@blociot Thank you, watched it but it seems publishing is limited to predefined topics, correct? I can not seen to publish a topic from a schematic.

@@seattledutch There is no instruction or block in the schematic for publishing to a topic. The procedure is two topic names should be defined for publish and subscribe in the LOGO MQTT configuration. Then a memory area is dedicated for publishing and subscribing to messages. All you need to do in the schematics is to transfer the desired value to the dedicated memory are. For example VW1 or AI1. This makes it easy to work with MQTT, but I would also like to see an instruction where we can define the topic name and the use it in the schematics. Maybe Siemens will add it in the future releases...

@@blociot Thank you! This is very helpful! Thank you for taking the time to answer my questions and your helpful videos. I’m a software developer veteran but new to PLCs and this helps a lot.

@@Mark-n4q3m thabks for your feedback, Mark. This is a feature that I wish existed. Currently, the LWE is limited and can't act as a datalogger. But I know the new LOGO supports downloading the log files from SD card in Run mode. I have not tried ot but it could be possible to download the log files from the web interface. I'll try it out and will update you.

@@blociot Thanks for replying, this sounds like a possible solution. My ultimate scenario is multiple PLC's/LOGO's controlling equipment, gathering data from thermocouples/pressure sensors/voltage monitors etc and exporting live to an Excel platform wirelessly. Could be a challenge with my limited knowledge.

@@Mark-n4q3m anytime. For your application, I think this video should be very interesting: ruclips.net/video/0fKBFmFBWQ4/видео.htmlsi=OXvf1YmBGMaX3jdm It needs a bit more effort, but you can easily use MQTT in new LOGOs to send data to a MQTT broker and log your data to a database like InfluxDB instead of Excel. Ofcourse you can log to Excel in a similar manner too. Please check our Industry 4.0 and LOGO playlist for detailed tutorials on this topic.

@@iran_siemens I believe Copilot is not released for all regions yet.

Hi @@PavlosKiriafinis. Do you get any error message?

Thr best would be contacting a Siemens rep in your region and ask of they have it.

Thanks for your feedback and time to watch this video. All be best with your cool projects. LOGO is a very interesting piece :)

Hi @@HoangAnh1810-p7q. I'm on vacation and will check it out once back within a week. Thanks for watching

I think state_topic is missing in the switch configuration, so it won't work. I've seen multiple topics on Home Assistant Community about this, all without a proper answer. Ideally, two-way communication should work, so when I turn a light using the logo, the switch state in HA updates, and when I use the switch in HA the light turns on. @blociot idea for another video :)

@@tjagusz @10:43 it's in big red letters below in the video

Hi@@simonmaton. What part did you find complicated? Setting up the server, onboarding the devices or using the client software? I'm a Siemens expert so can't comment on the complexity of Siemens platform. For me, Siemens is very easy to work with because I can figure anything out from the documentation. Also, what other vendor do you feel comfortable working with?

@@blociot Hi, thanks for replying, we are currently struggling with trying to get the M876-4 module to connect to the 4G network. The configuration requires a user name and password for the SIM card, according to every phone company who supplies SIM cards the is no such thing as a user name and password for the SIM, I'm currently testing with a Vodaphone card in Australia.

@@simonmaton I see. I hear you. Cellular is sometimes annoying. But if you have set up the modem using the wizard, defined the antenna, etc. properly, and entered the SIM info correctly, it shoupd work. I've commissioned several cellular modems and they all worked after some simple troubleshooting.

Hello, I only use RPI for lab tests. In production, I use IPCs or SBCs like Siemens IoT2050, Advantech mini PCs, etc. But I've been using RPIs for years. They normally work fine but their SD card and power supply sometimes fail. Using SSD drives instead of SD cards and a reliable power supply helps.

@@blociot yes i use ssd and now power supply with 5.1v. i will search for siemens.... thank u
