Abstract
A synchronization method, a control system and a slave unit for the time synchronization of at least two slave units, in which the slave units and the master unit are connected by two signal lines. A signal transmitted by the master unit returns to the master unit after passing through all the slave units. Two independent counters are provided in each slave unit, these counters being activated by reception of a reference signal transmitted by the master unit. The first time counter counts the time since the receipt of the reference signal via the first signal line and the second time counter counts the time since the receipt of the reference signal via the second signal line. The counter contents are read out as soon as the sum of the counter contents reaches a signal throughput time transmitted previously by the master unit.
