Abstract
Method of and system for transmitting signals, e.g. control signals, request signals, intermgation signals etc. in a control system comprising at least two units, wherein at least one of said units is designed to operate as a master unit and wherein at least one of said units is designed to operate as a slave unit. A plurality of channels may be used for the transmission, a first unit performs the steps of detecting a vacant channel and transmitting a signal via said vacant channel, and at least one other unit performs the step of scanning the channels for transmitted signals. The master unit waits for a reply when having transmitted said signal, and if no reply or an erroneous reply is received said master unit proceeds with the step of detecting a vacant channel by jumping to another channel. <IMAGE>
