Abstract
An industrial system for controlling backplane communication including a cluster manager linked to Input/Output modules via a multipoint low voltage differential signaling, MLVDS, bus through passive base plates. The MLVDS bus contains a transmission line and a reception line for the cluster manager. The transmission line of the MLVDS bus is shared by the Input/Output modules for receiving data transmitted by the cluster manager. The reception line of the MLVDS bus is shared by the Input/Output modules for transmitting data to the cluster manager. The Input/Output modules are synchronized in time with the cluster manager and configured to send data on the reception line of the MLVDS bus at respective scheduled time windows.
