An electric arc furnace and a caster in one material flow over OPC UA, where a slag foam collapse sets the month billed demand charge.
A steel mini-mill: 8 devices and 122 tags over OPC UA, and the only solution here that is batch and continuous in one material flow.
An electric arc furnace melts a heat to ISA-88 while a caster runs a strand continuously, and a ladle joins the two. The caster is the pacemaker and the melt shop is sized to run about a minute ahead of it, so a delay upstream propagates rather than being absorbed.
Nothing in the cost chain is a rule that says if fault then cost. Slag foam collapses, the arc radiates at the panels instead of the bath, meltdown stretches, the heat taps late, the tundish runs down, the melter pushes a higher transformer tap to protect the sequence, and the billed 15-minute demand peak moves with it.
It also shows Litmus Edge as an aggregator: the mill is republished northbound through the Edge own OPC UA server, so the full chain runs simulator to Edge client driver to DeviceHub to Edge server to MES.
Condition monitoring across a six-machine fleet over Sparkplug B, with the bearing prognosis computed on the Edge.
A 110/20 kV substation with six feeders on IEC 60870-5-104: transformer thermal margin, tap changer wear, and a full recloser sequence.
A six-machine bottling line, simulated end to end, that configures Litmus Edge itself and turns filler giveaway, CIP verification and downtime into money.
