DETAILED DESCRIPTION

STR571
This indicator allows reading/writing of up to eight variables on Modbus slave devices, with numeric ot text representation of the variables. It is possible to set the description and the measuring units with text or alphanumerical characters for each variable and also to rescale data on display. 
The number of variables shown per page can be set from 1 to 4, with auto-rescaling of the character sizes and of the consequent number of pages. 
Digital inputs allow the connection of a rotative encoder that further simplifies navigation of the data displayed and the parameters, or connection to panel buttons with programmable functions. In addition to the galvanically isolated master serial port with Modbus RTU/ASCII protocol, a second slave serial port enables polling from another Master device. 
Distinctive feature of the entire STR series is the innovative multilingual interface, with text menus allowing intuitive and quick navigation of parameters and visualization pages. 
The text menus are available in five languages and considerably reduce the need to consult technical manuals for initial set-up.
