CPLANE helps data center builders, operators, and the system integrators who serve them replace a patchwork of proprietary PLCs with an open, deterministic control layer. Cybersecurity is designed in. The stack keeps pace with GPU rack density.
When the spec is locked after civil and mechanical work, you inherit mismatched PLCs and protocols.
Oil and gas learned this. AI data centers are at the same point now. The operators who set the control standard during design hold the leverage on every later equipment decision.
Talk with an ExpertWe engage during design, before the controls spec is locked.
Equipment list, protocol choices, where remote access lives, and total cost compared with a proprietary PLC stack.
Live control starts on one isolatable system: a CDU circuit, a secondary chiller, or a single power zone. The rest of the facility stays on the installed stack.
CPLANE does not go around the integrator who already knows the facility. The SI, the EPC, and operations stay in the loop.
After SAT on the first island, sequence the remaining systems. Virtual DCNs patch in hours, not a full-facility outage.
One control layer for cooling, power, and the facility.
One Fusion 500 instance spans CDUs, power distribution, air handling, and facility-wide control. One platform. One security perimeter. One patch cycle.
Every CDU, chiller, and power lineup ships with its own PLC. Deterministic loops as fast as 20 ms are what liquid-cooled high-density compute requires. The box running the lobby thermostat will not do it.
Fusion 500 runs CDU, chiller, power, and air handling as isolated applications on one platform. No single hardware brand gates the build schedule.
A CDU circuit, a secondary chiller, or a single power zone. The rest of the facility stays on the installed stack until that island proves itself.
CISA advisories and a February 2026 U.S. Army red team make the same point: adversaries target internet-facing OT controllers. The red team found no vulnerabilities that allowed unauthorized access to control.
Fusion 500 is in production control at ExxonMobil, running a chemical terminal. Closed-loop AI control runs at a Texas A&M small modular reactor test facility.
The operators who set the control standard during design hold the leverage.
Talk before the next build locks the stack.
