I have learned MQTT by Python for a few years ago from your website, which helps me fully understand how it works due to your extreme details description and explanation. Thank a lots your effort and I really appreciate your work in free.
In this series of video, I can also learn more of MQTT in Node red and Modbus, which can help me current project in industrial environment. Thank a lots again.👏👍💪
Hi Steve. Been using your videos to get through Node-Red. I really appreciate it. I've got a question when it comes to using the modbus contrib library though. How would you go about getting the payload of more than 10 addresses but the addresses are not in order? I understand that we can adjust the quantity based from the starting address. But, what I'm trying to do is use multiple Modbus-Read nodes with an address on each one (I did it this way because I need the Topic field on the Modbus-Read node). This would have worked but I'm experiencing a problem of getting the data once I've logged more than 10 addresses/Modbus-Read nodes. The reason I need the topic field is that it becomes my identifier once I pass it to a custom dashboard I've made. Thanks!
hi, i clicked on the plc simulator and got the 404 screen, not found? do you have any suggestions on down loading the modbus simulator? also can the software find the modbus addresses and test an old message display with a few led lights and pushbuttons? thanks a lot...:)
On windows at the command line type ipconfig on linux and macuse ifconfig see itssc.rpi.edu/hc/en-us/articles/360001995831-How-to-find-your-MAC-Address-for-MacOS-Linux-Windows
Just wondering if you have been successful using Node-Red in a docker container? I'm trying to access Modbus registers connected to an RS232 serial interface (that is working well) on a Raspberry Pi, but cannot seem to get it connected. Any experience?
Hi Not node red but came up with the problem on home assistant. I think using the --net=host switch will cure it and you don't need the port mapping. docs.docker.com/network/host/ rgds steve
