Abstract
A method and communication system that provide an inexpensive approach that enables the times of events that are detected in IO device to be determined in a higher-level controller. The higher-level controller has a system clock and is connected to an IO link device to which multiple first IO devices are able to be connected. In addition, a second IO device is connected to the IO link device. The clock of the second IO device is synchronized by a synchronization device with the system clock of the higher-level controller. The status data that are provided by at least one of the first IO devices and the current time data that the second IO device supplies are transmitted simultaneously to the IO link device. The IO link device assigns the status data received to the received current time data, then transmits these data to the higher-level controller.
