Industrial and OT Networking
IEC 62443 lets a live plant be segmented in stages — zones and conduits first, enforcement later, no shutdown to start. Mapping what talks to what is free.
On a plant network the constraint is the change window, not the technology.
The unmanaged switch in a panel nobody has opened since commissioning is doing a job. The plant will not stop so it can be replaced tidily. That is the actual design problem.
Belden supplies industrial connectivity, copper and fibre built to survive a plant floor, and it is often what SECCOM finds already running behind that panel.
Arrange SECCOM to map what talks to what. For most plants it is the first time anyone has written that down.
What you get. A list of every device on the plant network, the zone it sits in and the paths permitted between zones. A sequencing plan built around your annual shutdown and your own outage calendar, not a delivery quarter.
Where SECCOM stops. Safety-instrumented systems stay with your process safety team. SECCOM designs around them.
