DICNET® (DEUTSCHMANN-Industry-Controller-Net)is a multi-master Fieldbus. At the physical layer according to the ISO-OSI shift model it corresponds to the DIN 19245, part 1. That means a connection between all participants in the net is established with an RS485-two-wire line.The physical arrangement is thus a bus system, at which the participants can be switched on and off as desired. From the logical point of view it is a token ring, that means that always only the participant who has the access authorization (token) is allowed to send to the bus.

Availability
DICNET is supported, beside of the accessoire DICNET-Adapter, by all cam controls as LOCON and ROTARNOCK as well as all operating units as TERM which feature a RS485 (DICNET) interface.
