A method for transmitting frames containing data between users of a ring-shaped communication system which has a master and at least one slave as users. Each user has at least one interrupt register, and one field of the at least one interrupt register is associated with an interrupt request and includes a value for an interrupt bit. An interrupt request which includes the interrupt bit is transmitted to the master by a slave in a frame designed as an empty frame. In addition, the empty frame has a toggle bit for all slaves which indicates the state of an interrupt request. |
