With DeweNET your measurement system can be controled remotely with ease of use you couldn't imagine before. DeweNET also serves as the center of Distributed Data Acquisition systems where you have multiple systems located either together or scattered across an entire continent. IRIG and GPS time will take care that data will stay synchronized, no matter how long the acquisition runs.
DEWESoft NET offers three basic modes of operation:
With these three modes almost any application can be covered. From single channel expansions over remote control to distributed measurements over hundreds of kilometers - everything is possible.
1:1 mode works with single measurement system and single client. In this mode there are two types of operation: full remote control and data view only. In full remote control the client computer acts like a master of the measurement system. When control clients changes to the setup screen, the measurement system also changes to setup screen.
However, in the "view only" mode, the measurement system acquires data, while the client computer can connect to it and view the "live" data... but it can't control the measuring system. A "view client" can look but not touch.
Multiple measurement systems and single client are used in case of distributed measurements or too high acquisition rates to be managed by a single measurement unit. The measurement systems have to be clocked synchronized either with hardware clock (one unit is the clock master, the others are slaves) or with the external clock source which is either IRIG or GPS.
All measurement systems have to run with same acquisition rate. In this case only one connection option is possible - the client is always the master. It starts and stops the measurement on all units in the measurement network. At any time the client has access to view mod e - but only to one measurement system (one-to-one connection like in single measurement system & single client configuration). Additional view devices are possible, but they can access only a single measurement system.
The third network configuration is to have a single measurement system controled by one 'master' client and additional 'view' clients. The master client is able to change the measurement system setup, storing strategy, start and stop measurements, and many more. The view clients are only allowed to take a few channels from measurement unit (up to the bandwidth limitation) and view and store the data on their local hard disk.
