CC-Link Fieldbus system

What is CC-Link?

CC-Link is an open fieldbus standard developed by Mitsubishi Electric in Japan. CC-Link enables communication between devices made by different manufacturers without any special interface adaptations and at high data rates (10 Mbit/s).

"Optional ASi Safety coupling circuit" :
2 ASi networks, 1 ASi Master.

Number of ASi networks, number of ASi Master

" yes, max. 4 A/ASi network ":
Cost-effective power for 2 ASi networks with 1 power supply (optionally supply of multiple Single Gateways by 1 power supply).

Operation with short cable lengths with standard 24 V power supply possible.


"no, max. 8 A/ASi network, redundant supply ":
1 ASi power supply per ASi network. Gateway is powered in normal operation from one of the two ASi power supplies.

Should one ASi power supply fail, switching to the other ASi power supply allows all the diagnostics functions to be maintained and the unaffected ASi network continues to operate.

" no, max. 8 A/ASi network ":

1 ASi power supply per ASi network.

1 power supply, 1 gateway for 2 ASi networks, inexpensive power supplies

Detects whether the same address has been assigned to two ASi slaves. Frequent error when using a handheld addressing device.

Recognition of duplicate ASi addresses

Checks the ASi line for interference effects such as noise, external voltages, ...

ASi fault detector

Using a C-program offers the possibility to run mini-PLC functions with a gateway.
