SOL/05 SCADA & PLC integration

Read straight off the PLC — don't just wait for someone to type it in.

Manual logsheets get you heat-wise records fast. Connecting SmeltSync to the PLCs and SCADA system already running your furnace, AOD and CCM removes the typing step entirely for the readings your automation already has — temperature, power, blow time, casting speed — and ties them to the same heat number.

Why plants add this on top of digital logsheets

A melter can log a tap temperature by hand accurately, but they can't log a continuous power curve, a casting-speed trend, or a temperature reading every few seconds. That data already exists in your PLC and SCADA historian — it's just sitting in a separate system that doesn't know a heat number from a hole in the ground. Integration means that data joins the same record as the manual log, instead of living in a second silo next to the first one paper created.

How the connection works

SmeltSync reads tag data from your SCADA/historian layer through a gateway process, matches timestamps against the heat currently open on that furnace or strand, and writes the readings into that heat's record. Manual entries and automated tag-reads sit in the same table — an admin can see which fields came from a person and which came from a PLC.

Compatibility

Every plant's automation stack is different, so we scope the exact tag list and protocol during the pilot rather than promising a fixed list upfront. As a starting reference:

Supported PLCs
Confirmed against your plant's specific make and model during scoping — [list actual supported PLC brands here].
Protocols
[list actual protocols supported — e.g. OPC-UA, Modbus TCP].
SCADA systems
[list actual SCADA platforms integrated to date].
Deployment
Gateway runs on-site; no readings leave the plant network except the values already sent to the dashboard.

Note for the SmeltSync team: replace the bracketed items above with your actual supported PLC brands, protocols and SCADA systems before this page goes live — see priority list item 10 in the site-rebuild brief.

We'll scope exactly what's readable from your PLC/SCADA before anything is promised.
