EVAL-CN0414-ARDZ

A single node system is often referred to as a PLC, whereas a larger system is often referred to as a DCS. Each node can control up to 16 analog field devices, sensors or actuators, either HART-compatible or analog-only, and the prototyping system can be extended to include as many as 16 individual nodes. The system can also be used for general-purpose precision analog data acquisition applications such as instrumentation, analog datalogging, or test and measurement.

The CN0435 application, from Analog Devices, focuses on demonstrating the development of a PLC/DCS system controlled by a Modbus master and exemplifies how the latest features of key components are used. A single node system is often referred to as a PLC, whereas a larger system is often referred to as a DCS.
