Daniel L Posted March 4, 2022 Report Share Posted March 4, 2022 I am interested in emulating a scrolling terminal screen (like the old VT100) Typically 24 lines of 80 characters per line. The HMI Variable TEXT seems to be limited to 64 characters which is much too short for the application. It seems to handle control characters, or at least a limited CR LF so it looks like it could do the display except for the character length limitation. My next option would be using 24 TEXT variables, one for each line. Any better suggestions ? Thanks, Daniel Quote Link to comment Share on other sites More sharing options...
MVP 2023 kratmel Posted March 6, 2022 MVP 2023 Report Share Posted March 6, 2022 I tried to do brute force experiment with 80 pcs 1 char variable in line. with 80 x 24 lines = 1920 MI used. Then 4096-1920=2176MI is free I do not try to download it to V1210... Maybe this emulation better to build on Unistream... Quote Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted March 6, 2022 MVP 2023 Report Share Posted March 6, 2022 Maybe use a Data Table with several string columns, then read out the Data Table line into a vector of MIs? Quote Link to comment Share on other sites More sharing options...

I do something similar with "List of Texts" fields. After every action controller does it writes a new line on top, old ones move one step down. This screen is usually called Status Terminal or something similar. On 3/8/2022 at 10:44 AM, AlexUT said: Is it worth the time and money? It my case no. It also doesn't help much with troubleshooting, but it looks good so I usually do it, especially on bigger screens. Quote Link to comment Share on other sites More sharing options...
AlexUT Posted April 3, 2022 Report Share Posted April 3, 2022 Good luck! If you wish-share result, and where it may be used. I'll be doing it with any suitable SBC. In any case you need an external keyboard. Hope you can look to realize VT100 as HTML page. .B.R. Quote Link to comment Share on other sites More sharing options...
