Low-Code Programming of a u-control web/IoT

[@juandanielespinozacaro9816]

if i change the ip for the usb port of the plc how can i restart the ip without open the u-create

[@juandanielespinozacaro9816]

I already tried to reset it with an SD with the RECOVERY.FILE file, but it seems that it didn't work and I don't remember the IP address

[@WeidmuellerGlobal]

Hey @juandanielespinozacaro9816, A Recovery of the u-control is only possible, within the operation u-OS. U-create web does not offer this feature. If you have already updated to u-OS, the file name is just without any suffix. The IP-adress of the USB port can not be changed. It is fixed to 192.168.10.202. If you don’t reach the u-control anymore, please send it to back to Weidmueller for service. Hope we could help you. :)

For a beginner someone like me this video is so helpful. I’m wondering where I can cheaply buy the starter kit !

Good👍, but How to develop program without PLC UC20-WL2000-AC and modules? Is there a controller emulator?

[@WeidmuellerGlobal]

@levsarkisov2686 At time, you always need the UC20-WL2000-AC to develop a program, i.e. there is no controller emulator available.

Kann ich das an DIN-Schiene im Unterverteiler montieren?

[@juandanielespinozacaro9816]

Is there a way to program the plc in an emulator to test the logic (without having to have the plc connected) and then implement it?

[@WeidmuellerGlobal]

The programme development environment is implemented directly on the u-control web server in the variant presented in the video. This has the advantage that the u-control can be programmed directly without a licence and without additional PC software installations. But of course this requires a u-control - an emulator for a PC is not available. However, you can also program your u-control without connected I/O modules and test the program logic. Our tip: Use internal variables for the actual programme logic and develop a simulation FB for the simulation of input signals. For "real" use, simply deactivate / delete the simulation FB and map the internal I/O variables in the variable table to the real inputs/outputs, which you can simply scan in the hardware configuration using "Auto-Detect". Software projects or test programmes already created on the u-control can of course be saved on your PC and loaded into another u-control.

I am using Node-RED on u-controller and I am using the Dashboard. I want to use SVG files, so I tried to download node-red-contrib-ui-svg, but it gave me the following error: 2024-02-26T14:23:31.479Z [err] npm ERR! Invalid dependency type requested: alias. I can install this node on my computer and it works fine, but not on the u-controller. Any advice? Thanks

[@schwillieh]

how/where can is scale analog inputs?

[@WeidmuellerGlobal]

@schwillieh By double click on the u-remote AnalogIn card, the configuration user interface opens. You can configure every single channel individually, e.g. 0..5V / 0..10V, -5 .. 5 V etc. or in case of our 4AI-RTD channel , passive temperature-dependent resistors, like PT100, or PT1000 can be configured, too.

does it support all IEC 61131-3 languages? what is maximum IO count suitable with this type of controller? is it SIL certified?

[@WeidmuellerGlobal]

Does it support all IEC 61131-3 languages? Answer: The variant shown in the video with the programming environment directly on the web server only supports programming in Function Block Diagram (FBD). However, our u-OS operating system can also be installed on the controller. This makes it possible to install a CODESYS runtime on the controller and to use native CODESYS on the programming device (e.g. notebook) as the programming environment (CODESYS supports all IEC 61131-3 programming languages). What is maximum IO count suitable with this kind of controller? Is it SIL certified? Answer: 64 active IO modules can be connected directly to the u-control web/IoT control system shown in the video, with up to 32 connections on one IO module. By using u-OS and CODESYS, additional modules can be connected decentrally via EtherCAT and u-remote couplers, again with a maximum of 64 active IO modules connected to each coupler. The IO modules also include SIL-certified u-remote modules (e.g. UR20-PF-O-2DI-SIL).

I have a u-controller that I want to use with Node-RED, but I don't know how to display the data on the Visualization tab. Can you please guide me in the right direction?

[@WeidmuellerGlobal]

Hey @sadeepthajayathilaka3144, Please use the widget within the smart visu. This widget can display web-pages, like NodeRed dashboards. By entering the NodeRed dash board URL into the assigned field of the widget it will be shown within the Smart Visu. Hope we could help you. :)

@ellerGlobal Thanks

Clever little system. But quite pricey.
