Hello, I am new in JS and I need just a direction, where to go forward. I did a small application (a traffic light) with AJAX to change the colors/lights based on the variables and logic from an S1200. I have also send commands (write variable to PLC) to start and stop traffic light. Next, I want to make more complex application with screens and animations which will require more memory and space. Should I make just an simple html with JS that read/write variables in JSON format and from there to take the data and make the complex app or should make complete app and downloading to s1200 PLC? Thanks for all ------------------------------------------------------------------------------------------ |

My suggestion is to build the application outside the PLC because there is very little room *inside* the PLC memory to contain all the required logic AND images necessary for animations and multiple screen. If you need something more involved, consider a HMI configuration with screens and animations (that runs in a special piece of hardware - HMI, or that executes on a PC - WinCC Runtime). TIA Portal fully supports all that without dealing with JS. Once you hit the limit in just the s7-1200 PLC, you have to upgrade to a higher level PLC if you use JS/JSON, which can suddenly make a project less cost effective - especially with the relatively low cost of basic HMI panels with all the options built right in. [NOTE: I do not work for Siemens, nor any distributor or sales channel related to Siemens. I'm just an end user who sees the value in the basic panels over the time spent building AND maintaining custom JS/JSON "hmi"-like code. You still need a PC type device to visualize it, so add an HMI instead of a PC.

It would be better to use dedicated devices like IoT2020/IoT2040?
