This mean recompiling/rebuilding the code for PV? Sure this will cause different unexpected errors on exchange between HMI and old slc.
Not if you are good, or hire someone who is good.
The Panelview Standards are pretty basic. There is not going to be anything buried in scripts or special code to deal with.
As long as the person doing the conversion fully understands PB32, that person should be able to do a flawless conversion just by having the original panelbuilder file, and may not even need the SLC code. Sometimes the use of ASCII variables and a couple of other less common things can present some extra hurdles.
There should be no changes required to the SLC software if you use the same DH485 connection. Even if you opt to use a different channel to connect an upgraded HMI, most likely, the only thing you will need to change or verify would be the channel settings of the other channel to be used.

At least I do not have such experience. Probably for now the best solution is to restore the system, and after, when I'll have some more spare time, to spend it in de-bugging while moving to new HMI.
I concur. Find a Panelview Standard unit that is compatible and get the equipment running. Ken gave you good part numbers already.

Or I do a mistake now? As soon as I was not digged the PV program deep, while I opened it with PanelBuilder32 (it runs under w8/32bit good
) I watched a kind of variables map that is intended to make a PV understand a flow from slc and back to it. And I am not sure that another HMI will have someting similiar, that will give me painless way to move to it. Or it is possible?
You are probably looking at the tag list in the PB32 program.
When you migrate to a newer platform, be aware of the DH485 connection that you are using now. I would suggest that you look at other communication options that are more widely supported. In order to do that, it would be necessary to answer a couple of questions:
1) What model is the SLC to which it is connected?
2) What is the distance (in feet of cable) between the SLC and the Panelview?
I, personally, love the Red Lion G3 series HMI. You can connect them directly to the DH485 network with some research and some cable fabrication skill. They will be powered by 24vdc and consume much less power than the old Panelview and much much less power than the Panelview Plus. So you would not have to worry about changing power supplies or sources. Also it is not to difficult to import the entire tag database into Crimson software (which is a free download). This helps avoid errors in recreating tags, which is the most common errors one would make during a manual reproduction.
I have no idea what sort of support Red Lion offers as far as distributors in your country. For that reason, it might be worth considering upgrading to a PanelView Plus. In some cases, it is possible to import the panelbuilder32 program and do an automatic conversion in order to use the still available Panelview plus.
I hope this helps, and good luck in your hardware search.
