Process Automation


Process Automation Background

Process Industry Automation history The “Process Industry” includes the waste water treatment, food & beverage, chemical, oil & gas, and pulp & paper industries. In the past, plant operators had to physically monitor performance values and the quality of outputs to determine the best settings on which to run production equipment. Process automation simplified this with the help of sensors at thousands […]


PA (Process Automation) Basics

What are the components of a PA network? PROFIBUS PA ( Process Automation) was designed to work along with PROFIBUS DP (Decentralized Periphery) to make a consolidated network using DP for high-speed communications and PA for for process environment. A network consists of a DP master (controller), a DP segment, a DP/PA coupler and the process network with slave devices. Fast […]


PA Profile for PROFINET

What is the PROFINET PA profile? PA networks are designed to be operated as process  “islands” within a larger PROFIBUS DP controlled network. The total network could consist of several of these “islands” all controlled by a single PLC/DCS. Each PA “island” starts with the DP/PA coupler which acts as the PA master and consists of several PA devices on […]
