Official maintenance of ISO 11783 is done by ISO TC 23 / SC 19 / WG 1 and WG5, however the Agricultural Industry Electronics Foundation (AEF) helps guide the ongoing direction of ISOBUS, organizes PlugFest events where many companies meet to test together, and provides formal ISOBUS conformance test tools. The ISOBUS standard specifies a CAN network for control and communications on
