Control and valve drivers

Diinef's control architecture consists of two PCB's, a Master/Control PCB and a Slave/Driver PCB. The PCB's communicate over a fast 100 Mbit Realtime PowerLink bus and up to 800 solenoids can be controlled with 1ms sample time on the same bus. 

The digital valve Driver can be applied by itself for valve control and act as a master node for valve control by other Driver cards. By adding a Master card more sensor inputs are made available, and more processing power can be dedicated for application control. The Driver can then be focused on valve activation and monitoring.
