Details
CC-Link was originally developed by Mitsubishi. CC-Link is based on serial RS485 network, while CC-Link IE is based on Ethernet network.
On CC-Link IE there are more protocols available, for example, SLMP, SLMP Scanner, or CC-Link IE Field Basic.
Cognex devices can support the below protocols, but please note that not all Cognex devices support all of them.
CC-Link
- RS485 based
- needs CIO-MICRO-CC module
- only old In-Sight cameras with firmware 4.x.x support this (it is not supported in 5.1.0 and above firmware versions)
- other Cognex devices do not support this protocol
SLMP
- Ethernet-based
- camera is the client and controller (like PLC or robot) is the server
- event-controlled, acyclic communication
- supported on In-Sight Explorer cameras
- not supported on In-Sight Vision Suite cameras (for example D900, L4000, IS2800, IS3800, L38)
SLMP Scanner
- Ethernet-based
- camera is the client and controller (like PLC or robot) is the server
- cyclical communication (polling interval is set on the client side)
- supported on In-Sight Explorer cameras and on In-Sight Vision Suite cameras
CC-Link IE Field Basic
- Ethernet-based
- camera is the server and controller (like PLC or robot) is the client (this is the opposite of the SLMP Scanner)
- cyclical communication
- supported on In-Sight Explorer cameras with firmware version 5.7.0 and above
- supported on DataMan devices with firmware version 6.1.7 and above
- not supported on In-Sight Vision Suite cameras (for example: D900, L4000, IS2800, IS3800, L38)
