Distributed Process Intelligence (DPI) - General Information



The PD 600 series of Distributed Process Intelligence units  - DPIs - has been developed as the third generation of P-NET fieldbus programmable master devices, for use as distributed computing elements within highly complex as well as simple process control systems. Another term for this type of device is Programmable Automation Controller, often referred to as PAC.


The PD 600 series is part of a new family of standard process control devices, the M36 family, which can be mounted on a DIN rail. When mounted, communication is automatically enabled through the Light-Link interface. Power is applied to all devices on the same rail by a common power bar. These facilities make mounting, connection, replacement and addition of devices very quick and easy.
