Learn how process plant operators can modernize existing PROFIBUS PA installations with PROFINET while keeping field devices and cabling in operation. The article explains how PA gateways such as Softing pnGate PA support brownfield migration, lifecycle management, OT security and CRA readiness.
Along with HART and Foundation Fieldbus, PROFIBUS is one of the most important communication protocols for digital field devices in the process industry. By supporting digital communication and manufacturer-independent device exchange, it offers the best conditions for controlling, monitoring, and streamlining production processes. But to make the communication architecture fit for the requirements of IIoT applications, faster data transmission is needed. For this purpose, modern Ethernet-based PLCs are available, which allow existing PROFIBUS networks in the process industry to be expanded with modern and highly functional segments.
When it comes to field device management, the process industry still seems to overlook the two key aspects of protocols and ‘accessibility’ – at least that’s the impression we get from the tools provided by instrument suppliers. Softing Industrial has filled this application gap with two mobile enterprise solutions, which are the first in the world to support the three major protocols of HART, FOUNDATION Fieldbus, and PROFIBUS PA in a single device for connection to intelligent field devices while also offering an interface for integration and data provisioning.
The 4..20 mA current loop with HART interface remains the industry standard for transducers. A fieldbus interface with device integration capability and scriptable configurability offers an inexpensive retrofit for these devices for operation with Foundation Fieldbus and PROFIBUS PA.
