Hardware
LinkVion Box (CM4)
A small industrial box that runs on its own next to the machines, with the same LinkVion you would install on a PC.
Configuration
Specifications
- Module
- Raspberry Pi CM4 — 4 cores at 1.5 GHz, onboard eMMC
- Carrier
- Dual-Ethernet CM4 carrier board in a metal case
- Network
- 2 × gigabit Ethernet — one for devices, one can be kept for EtherCAT
- OS
- 64-bit Linux (Debian 13) + real-time kernel 6.6
- Serial
- RS-485 via USB adapter (FTDI, CP210x, CH341 drivers built in)
- Size · power
- Provided with the final configuration (ask us)
Boot · performance
On at power-up
2.9 skernel loaded
8.4 sweb screen up
10.9 sOS boot done
Measured by us on 2026-08-21. The web screen opens before the OS reports boot complete. Not re-measured on later releases.
- Mitsubishi MC, 10,000 words per cycle in 16 ms — release build, loopback, 2026-07-15. Real PLCs add network round trips.
- Can run an EtherCAT master (real-time kernel + dedicated port). For jitter-critical setups, a board with a PCIe slot is recommended.
- Starts as a service at power-on, with login and roles; passwords in settings are masked on screen.
- Upload a signed update file (.acfw) on screen; signature, target and hash are checked, and a backup is kept to roll back.
