The communication device comprises a coordination device.

Communication device, communication system, and method for synchronized transmission of telegrams

An automation device is provided, which comprises an operating system having a first system clock and a communication system having a second system clock. The first system clock is intended to control a system time cycle of the operating system, and the second system clock is intended to control a system time cycle of the communication system.
