Common faults
What usually fails on a unit like the 840D 6FC5210-0DA00-1AA1
Industrial PCs, panel PCs and machine networking hardware fail mostly in power supplies, storage, fans and displays. Repairing the original unit keeps the operating system, licences and machine software as they were.
Won't power up
A failed internal power supply or DC-DC converter, or a motherboard power fault.
Storage and boot failures
Worn-out hard disks, SSDs or CF cards. The data can sometimes be recovered and the system cloned to new storage.
Overheating and fan failure
Clogged filters and failed fans cause shutdowns and slow, unstable operation.
Display and touch faults on panel PCs
Backlight, LCD or touch screen failures, as on operator panels.
Network and interface faults
Dead Ethernet ports, fieldbus cards or serial interfaces, and failed industrial switches.
First checks
What to check before calling an engineer

Safe for plant staff

- Check fans and filters.
- Back up data and licences if the unit still boots.
Leave to a specialist
- Motherboard and power-supply repair.
