Read full descriptionHide full description
Domat Visual is a free application for remote access to SoftPLC/MiniPLC/mark... controllers for heating, ventilation, air condition and energy monitoring and control. With Domat Visual, the control panel of your controller is always at your fingertips. The controllers must be programmed and commissioned, and must be accessible over the Internet or in your local network. For communication with SoftPLC/MiniPLC process stations, the app uses a LCD menu definition file, which must be uploaded into the mobile device, and displays values in a similar way as they are presented on the LCD display of the PLC. The mark… process stations use apart from the LCD menu also graphic panels. The text menu definition and graphic definition are uploaded as separate definition files. Depending on the user rights, it is possible to read / change values, such as temperature, humidity, pressure, light intensity etc., inclusive alarm acknowledging and time schedule setup. The application supports more PLCs and can be configured for local access from a LAN as well as remote access from the Internet. The switching between local and remote access is fast and simple.

*** Requires a corTalk® RBT1 or RMU123PGM and RMU3 to use. *** Contact us at 'sales.rmu3@mobiltex.com' to purchase. This app is for configuring the corTalk® RMU3 (Remote Monitoring Unit 3) with a Bluetooth configuration interface. Both the RBT1 or RMU123PGM are compatible. They both function as a complete RMU3 programming interface but only requires the Bluetooth connection of your phone to use. The RMU3 is used to monitor a cathodic protection rectifier with accurate measurement of a wide variety of signals; it can also control the rectifier for survey operations by switching a relay at precisely timed intervals. This app allows access to diagnostic information on the RMU3 and allows setting up the configuration to meet the customer's needs. Note that measurement data logs, due to their size, can only be extracted from the RMU3 using the PC configuration application through the USB port. The app allows full configuration of the RMU3 including - slot measurement types - limits - slot scaling and offset - relay options - instant off timing - interruption On/Off/Cycle Other features include the - viewing of readings and their limits - detailed status screen for troubleshooting - integrated manual - wiring diagrams for each measurement type The RBT1 and RMU123PGM is always in a Bluetooth pairing mode and requires a pairing code entered on the app. The pairing code (default=123456) can be found and changed with the app. Once paired, the iOS device can reconnect without needing to re-enter the code. The RBT1 pairing code can be reset by tapping the RBT1 5 times in 10 seconds with a user-supplied magnet.
