                  6   TP bit structure


































                  Figure 16: TP bit structure

                  A “bit” can have two logical states, i.e. “0” and “1”.

                  Technical logic in KNX TP:

                          During logical state “1” no signal voltage
                          During logical state “0”  signal voltage

                  This means that if several bus devices transmit simultaneously, the logical state “0” will
                  prevail!
