MinMessage - Data Security

Secure measurement data acquisition is an often overlooked requirement. Data networks and PCs are not secure elements; networks can collapse and PCs can crash. The consequence could be the loss of important measurement or operational data. Using Message devices eliminates this risk because measurement data is stored within the device. In the event of a PC failure, any missing measurement data can be retrieved from the Message device's data logger.

Internal data storage, data logger

A data logger is a non-volatile device for measurement data acquisition. Data is stored and can not be lost. The data logger in the MinMessage functions as a ring buffer meaning that the current data is always being saved. This permits interesting applications such as an industrial black box recorder, guaranteeing uninterrupted data acquisition.

Storage capacity

Storage capacity is 1 MB (100 000 measurement values with time stamp).

Data transfer to PC

This can take place both online and offline. In offline mode, data is stored temporarily in the device and can then transmitted, for example, once a day to a PC. The data can then be evaluated on any PC. In online mode, data is not saved in the device but at the PC. This storage method can be triggered so that the saving of data in online mode can also be time managed.
A combination of both modes is also possible. Data can be saved in parallel in both device and PC.

Time stamp

The MinMessage device always stores data with time and date stamps. Resolution is within milliseconds.

"Devistore" - adaptive storage procedure

Delphin's in-house developed adaptive storage procedure "Devistore", enables extremely dense data compression.
The level of storage density is automatically adapted to the rate of measurement value changes. If a channel's measurement values only change slowly or not at all, then little or no storage space will be required. If measurement values change rapidly then a higher storage density is required.
