Modernizing process control: HMI upgrades add security, S88 benefits
A new human machine interface (HMI) from Siemens Energy & Automation Inc
Siemens Energy & Automation Inc. is intended to modernize existing Emerson Provox process control systems. Simatic PCS7 / PVX OS HMI, available for both batch and continuous applications, provides the benefits of redundant S88 batch management without changing the existing controller hardware and configuration. By upgrading the original HMI, process plants can maximize their ROA, reduce time to market, and increase throughput. The existing controller and controller configuration are left untouched during the migration thereby minimizing revalidation costs and allowing the upgrade to be performed while the system is still online.
The company notes that enhanced security features, including electronic signature for 21 CFR Part 11 compliance and electronic batch records, make validation easier and further reduces time to market. System automatically generates tags from the controller configuration and comes standard with symbols and faceplates designed specifically for Provox point types. Other features include graphically monitoring batch executions, fast recipe creation and editing, and the flexibility to modify batch parameters during runtime, all using the optional redundant batch manager.
The new HMI was announced along with the latest release (version 7) of Simatic PCS 7 Process Automation System , which is said to give plant operators new ways to minimize total cost of ownership, protect automation assets, increase plant availability, minimize downtime, optimize process performance, and modernize existing installed systems.
