scales. Depending on the needs, communication with the module may be
established by the following interfaces: RS232, RS485, Ethernet, Profibus
and ModBus protocol. MW-01 Module may cooperate with PUE 5, PUE 7
terminals or PC computer.
Operating of the weighing module MW-01 from a PC level is carried out with
a computer software “MwManager”. A detailed description of the application
is included in the further section of the MW-01 user manual.
2. PRECAUTIONARY MEASURES
A. Please, read carefully this user manual and use the device according
to its intended use;
B. Weighed loads should be placed possibly in the central setion of the
