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.
