Abstract
The invention concerns a device for transmitting data between a serial data bus and working modules, wherein the data bus is connected to a bus node in a bus module having at least two serial communication ports which are connected to ports of a hub connected to or integrated with the bus node, wherein the communication ports are designed for the connection and for the power supply of the working modules and wherein at least one of the working modules is designed as an actuator and/or I/O module comprising a serial-to-parallel converter for the parallel connection of actuators and/or I/O interfaces provided on or connected to the respective working module.
Claims11
A device for transmitting data between a serial data bus and working modules, wherein the data bus is connected to a bus node in a bus module having at least two serial communication ports which are connected to ports of a hub connected to or integrated with the bus node wherein the communication ports are designed for the connection and for the power supply of the working modules, and wherein at least one of the working modules is designed as an actuator and/or I/O module comprising a serial-to-parallel converter for the parallel connection of actuators and/or I/O interfaces provided on or connected to the respective working module:
- wherein the serial connections between the hub and the working modules are IO link point-to-point connections, wherein an IO link point-to-point connection has a common single electrical line for clock pulses and data, wherein the hub is the IO link master, and wherein the respective serial-to-parallel converter in the working modules is an IO link slave.
