Forget paper checklists. Check I/Os directly on the machine – where sensors and actuators are located. IO-INSPECTOR is an independent third-party tool for commissioning and functional testing in industrial automation environments. With your iPad or iPhone you can observe, document and - if approved, technically permissible and safety-compliant - switch/control signals on site. Less shouting in the workshop, less manual checking and more clarity right where the work takes place. WHY IO-INSPECTOR? • Project and variable import (for TIA Portal® projects): Import variable lists from common export formats (e.g. .xlsx or .csv). IO-INSPECTOR adopts the structure, data types and comments from the file provided - manual re-entry is not necessary. • HMI View Smart Connector: Quickly connect to your system and conveniently access information relevant to commissioning. The Smart Connector is intended to simplify connection and access to the required displays/views in practice - without having to imply an official manufacturer affiliation. • Fast system connection: Detect and connect devices in the local network quickly and clearly. • Live status and targeted control (OPC UA): Connect to compatible controllers via OPC UA and check signals in real time. • Observe: Track changes immediately. OPC is also accessible via the WebSocket protocol. • Control: Set outputs or markers specifically (Force/Modify), provided this is activated in the environment and meets the safety requirements. • Diagnostics: Identify problems more quickly, such as cabling or logic problems. • Digital documentation (PDF): Check off test steps digitally, add notes (e.g. “Sensor defective”, “Adjustment required”) and export a PDF report with your company logo and timestamp. • Filter and search: Filter by status (“Open”, “Done”) or search directly by symbol name. • Mark changes (round-trip support): Mark typos or name adjustments in the app so that you can later apply them in your engineering project in a controlled manner. • Share and collaborate on projects: Share projects so colleagues can continue with the same project status - including testing status and documentation progress (depending on the sharing/export method chosen). TECHNICAL NOTES/REQUIREMENTS • Compatibility: Developed for environments with SIMATIC® S7-1200 (FW 4.0+) and SIMATIC® S7-1500. • OPC UA: OPC UA must be activated on the CPU. Basic access may not require an additional license depending on your configuration; Actual requirements depend on device, firmware and project configuration. • Signals: Supports digital and analog signals (depending on project/export data and target system). • Network/Offline: Use in the machine's local WLAN; Project-related features can also be available without the Internet (depending on the scope of functions). PRICES • Download IO-INSPECTOR for free to create projects and use network scanning. Upgrade options are available for extended functions (e.g. project import, HMI write access (power tags), PDF export, OPC interface, HMI Smart Connector). • Download IO-INSPECTOR and simplify commissioning. Legal notice/trademark: IO-INSPECTOR is an independent third-party software. SIMATIC®, TIA Portal®, S7® as well as S7-1200 and S7-1500 are trademarks of Siemens AG. This app has no business relationship with Siemens AG and is not developed, supported or distributed by Siemens.
