VT100 emulation on V1210

Recommended Posts

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 ?

Maybe use a Data Table with several string columns, then read out the Data Table line into a vector of MIs?

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.

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.
