Modernize SCADA without taking the line down.
Salem moves unsupportable DOS, HMI, and SCADA systems onto a modern SCADA platform, like Ignition, Movicon, Avena Edge, and Rockwell — proving the new system against live production before cutover. Zero downtime, and none of the process logic built over decades is lost.
End-of-life control systems don’t fail politely.

Shadow Mode proves the new system before you switch.
1
We build the new Ignition system and feed it the same live process data as the system in production.
2
It runs in parallel — in the shadow of the real system — while we validate its behavior against live operations.
3
Only once it matches do we cut over, on a planned window, with a rollback plan ready.
4
The result: a modern platform goes live with zero production downtime and no surprises.
End-of-life control systems don’t fail politely.
Either you take the line down to switch systems, or you keep running something you can no longer support. Shadow Mode removes that choice — the new system earns its place in production before it ever takes control.
