COMMUNICATION
Communication protocol can be two, three or four wire system (such as RS-485, RS-323,RS-422),or can be assigned by user. band rate 3009600bps can be set by internal parameters at will. Interface is isolated from mainframe by photo-electricity to improve system reliability and data security. The maximum communication distance is 1 km.Upper microcomputer can collect various signals and data to from energy managing and controlling system. Using SWP data collector and SWP NUBAN industrial control configuration software, several GN instruments can be on-lin e communicated with one or more microcomputers. The system uses main-subordinate type of communication to from various energy managing and controlling systems. The control loop only needs one two-wire(or three-or four-wire)cable to communicate with upper microcomputer, which can call the device number set by user, call on-line data of instruments at any time, and set internal parameters
PRINT CONTROL directly connect with different serial printer, communication method is RS-232
PRINT ACCURACY the same as the instrument measuring accuracy
SETTING METHOD
Front panel touch keypad digital setting
Keep set values permanently if power breaks down
