Collaborative process automation

The evolution of the traditional distributed control system (DCS) into today’s

more capable and all-encompassing process automation architectures has

been chronicled by analysts at the ARC Advisory Group as the advent of

the collaborative process automation system, or CPAS. In simplest terms,

‘collaboration’ implies the need for systems to share information in order

to perform optimal control actions and for people to make sound business

decisions. For this to become reality, a culture change needs to occur,

including using an environment that allows field devices, various automa

tion systems, and applications to share information without barriers. CPAS

is that environment.

The SD Series I/O product family includes DIN Rail horizontally or vertically mounted digital

and analog modules, as well as integration with intelligent field devices and protocols using

PROFIBUS DP, HART, IEC 61850. IEC 60870-5 104. DNP 3.0. and Modbus TCP communications.

Hardwire I/O and fieldbus I/O coexist and use the same function block library to build real-time

control applications.

Traditional SD Series analog input modules interface with field inputs such as pressure and

flow transmitter signals, thermocouple inputs, and resistive temperature device (RTD) inputs.

Analog output modules provide output signals to adjust final control elements such as control

valves, positioners, actuators, etc.
