CiA technical groups

CiA technical groups are hierarchical structured. The top-level CiA technical group is the CiA Technical Committee (TC); sub-layered are the CiA Interest Groups (IG). There are three active IGs: CANopen, CAN FD and commercial vehicles. The IGs manage their related Special Interest Groups (SIG) and Joint Task Forces (JTF). JFTs are established jointly with other nonprofit associations. All these CiA technical groups develop CiA specifications and recommendations. Each CiA member may participate in any group. The groups decide on consensus, meaning they discuss until everybody agrees on the compromise.
