Indicator STR571 is designed as a flexible and fully customizable interface for sensors, I/O modules, signal converters, and generally for instrumentation with Modbus-RTU output signal.
The device allows up to eight variables to be read/written to Modbus slave devices, with representation of variables in both numeric and textual formats; both description and measuring unit for each variable can be freely set in alphanumeric characters, and if necessary, the data can also be rescaled in display. The number of variables displayed per page can be set from 1 to 4, with auto rescaling of font size and consequent number of pages.
In addition to the galvanically isolated Master serial port with Modbus RTU/Ascii protocol, a second Slave serial port makes querying from another Master possible.
STR571 interface is quickly configurable via NFC with MyPixsys APP, without the need to power up the instrument or via multilingual text menus accessible by front keyboard. The device is equipped with a mini-USB port that allows programming also via software MyPixsysLab (see Software menu beside).
