DP slave device

Slave devices only require a small part of the bus protocol. A slave device is a passive device. Slave devices are peripheral devices such as input devices, output devices, valves, drives or measuring transducers.

A PROFIBUS-DP slave device is a peripheral device that reads input information and sends output information to the peripherals. There are also devices that only provide input information or only output information. The amount of input information that can be logged and the amount of information that can be output depends on the device. A maximum of 246 bytes of input data and 246 bytes of output data can be processed.
