Hi,
>Could you explain "Peak HMI" a little ?
PeakHMI is a full featured HMI that is very easy to use. We designed it so scripting is not required. It has a powerful scripting engine. Most users never use it. We do not have limits on tag count, graphic count, drivers, etc. Really no limits. All the drivers are native (about 25 last count), no DLLS, .net, OCX, etc. The only external files needed are if you are using OPC and the needed files are in the installer.
>Is Peak HMI good for trending ?
Yes PeakHMI has extensive trending. On the project screen shots web page you see that one customer project had trends on almost every screen of the project.
>..can you grab tags from 5 or more plcs ?
Yes, PeakHMI can handle 5 tags. It can handle 1000's of tags.
>...5 ContolLogix plcs
PeakHMI can communicate with ContolLogix and it does not need RSLinx.
We have extensive help files and about 27 demonstration videos. The demo/trial installer is fully functional. It has a few 'count' & time limits but the program can be fully evaluated.
And finally, we have excellent support.
You can contact support at hmisys dot com, if I can be of more assistance.
