Unified vs PLC

This app allows hosting different HMIs to monitor and control a plant or machine. You can create the HMIs with the Unified-E App Designer and publish them on the Unified-E App Manager. Unified-E is a software product which is used to operate machines or plants with a smartphone. App development time is drastically reduced by using the "Unified-E App Designer" software, where you can define both the HMI views and push notifications for your individual HMI app. No app programming knowledge is required. There is a Gateway PC required which connects smartphone with machine and ensures that communication is secured and only granted for authorized users. The "Pro" license also allows operating a machine via the Internet without performing any configuration on the firewall or router. By now there are already multiple Unified-E endpoint adapters, e. g. for the S7-, ControlLogix-, Modbus- or OPC UA interface. The software, user manuals, licenses and further information can be found on the website ww.unified-e.com. For developers and integrators all licenses are for free.

PLC-Inspector is a professional diagnostic tool for Siemens LOGO! controllers. Read memory, follow changes live and set registers, over Modbus/TCP, directly from iPhone, iPad or Mac. KEY FEATURES • Memory reading VM memory, analog inputs (AI) and analog outputs (AQ) of your LOGO! in real time. • Register writing Enter values in decimal or hexadecimal and send them to the controller. The app checks what the controller reports back and says so separately when the confirmation does not match the request. • Safeguarded writing Write mode has to be switched on deliberately and expires when you leave the view. Before every write there is a confirmation showing register and value in plain text, which can be switched off for a working session. • Bit-level visualisation Every register as a 16-bit value with colour-coded bit display. • Change detection Changed values are highlighted in orange. Jump between changes with the arrow buttons. • Auto-refresh Automatic updates in intervals from 0.5 to 10 seconds. • Multiple stations Manage any number of PLC stations with individual settings. APPLICATIONS - Commissioning and fault finding on site - Mobile process monitoring - Analysis of memory contents - Training and education TECHNICAL DETAILS - Protocol: Modbus/TCP (default port 502) - Reading: Read Holding Registers (FC 03), automatic splitting above 125 registers - Writing: Write Single Register (FC 06) with echo verification - Supported controller: Siemens LOGO! 8 (0BA8) NOTE The app needs a network connection to the LOGO! controller. The Modbus server must be enabled in LOGO!Soft Comfort. Developed by spiritdev Softwareentwicklung GmbH - your partner for industrial software solutions.
