iSystem vs PLC Signal Explorer

iSystem is an iOS utility app that provides useful information and statistics about your iOS device, such as: • device and operating system information. • flash memory and RAM usage statistics. • your current longitude, latitude, altitude, air pressure with a map. • the device's current angular position. • a list of built-in fonts. • WiFi & cellular data usage statistics. • A list of nearby Bluetooth devices.

PLC Signal Explorer is a powerful industrial utility designed for PLC engineers, automation specialists, and technicians who need a faster way to understand and trace PLC signals across projects. The app bridges the gap between PLC hardware tag tables and SCL software blocks by intelligently linking physical I/O addresses to their corresponding signals inside Function Blocks. This makes troubleshooting, diagnostics, and system understanding significantly easier and faster. With support for common industrial file formats, PLC Signal Explorer allows you to load tag tables and SCL blocks, then instantly search across addresses, tag names, signals, blocks, and comments. Smart matching highlights the most relevant signals, helping you quickly identify relationships that are often difficult to trace manually. Key Features: • Smart signal matching between PLC tags and SCL blocks • Instant search by address, tag name, signal, block, or keyword • Clear separation of INPUT, OUTPUT, INOUT, and STATIC signals • Support for CSV, XLSX, SCL, and XML file formats • Dark and Light mode with persistent user settings • Built-in SCL state machine parsing for deeper insight • Designed for offline use with no cloud dependency PLC Signal Explorer is built as a practical tool for real-world industrial environments, helping engineers save time, reduce errors, and gain better visibility into complex PLC logic.
