HMI & SCADA Development FAQs
What is a High-Performance HMI and how does it improve operator efficiency?
A High-Performance HMI strictly follows ISA-101 recommendations to minimize operator cognitive load. Instead of using complex 3D graphics and flashing bright colors everywhere, screens rely on neutral gray tones and reserve high-contrast colors exclusively for alarms or abnormal process conditions. This enables operators to identify process anomalies, evaluate root causes, and react significantly faster.
Can you migrate legacy PanelView or WinCC flexible screens to modern platforms?
Yes. We regularly migrate obsolete operator interfaces (such as legacy PanelView 1000/1200 or WinCC Flexible) to modern platforms like Ignition Perspective, WinCC Unified, or FactoryTalk View. We extract tag databases, re-map communication tags to modern OPC UA standards, and re-architect graphics to high-performance widescreen layouts.
How do you manage alarm floods in large-scale SCADA systems?
We implement rationalization techniques defined by ISA-18.2. By categorizing alarms into strict priority tiers (Critical, High, Medium, Low), applying state-based alarm suppression during startup/shutdown sequences, and configuring alarm shelving, we eliminate 'nuisance' alarms so operators only receive actionable, high-priority notifications.
Is remote web or mobile access to our SCADA system secure?
Yes. We design remote web access using secure HTML5 platforms (such as Ignition Perspective) using TLS/SSL encryption, multi-factor authentication (MFA), and integration with enterprise Active Directory / LDAP servers. Network traffic is routed through encrypted VPN tunnels and DMZs in compliance with IEC 62443 industrial cybersecurity standards.
