Universal and galvanic isolation
Major benefits of TopMessage devices are that inputs and outputs are differential, high-precision and galvanically isolated – from each other and from the power supply. Earth loops and non-isolated sensors therefore present no problems. This unique system architecture prevents earth loop distortions and enables the measurement of non-isolated signals.
The TopMessage device has several serial ports for attaching external equipment (e.g. scales, modems, large displays). Communication takes place via Modbus (LAN). PROFIBUS DP is also optionally available.
Data storage functions
The integrated data memory can be partitioned and triggered to enable users to save their data either continuously or according to specified events. A drag and drop option makes it easy to assign connected channels to storage/memory groups. In the same way users can save data from virtual channels - i.e. channels that extend the functionality of data acquisition systems.
The ProfiSignal software is used for both manual and automatic data memory read out. Online visualization is also available as well as analysis of the data memory's archived data.
Redundant storage within the device means data is secure even in the event of a PC or network failure; data security is important, and not just for FDA21CFRPart11 compliance.
