  • Page 5: Application And Meter Design

    1. APPLICATION AND METER DESIGN The N30U meter is a programmable digital panel meter destined for measurements of signals originating from standard sensors destined for temperature measurements and for the measurement of analog standard signals applied in automation. Additionally, the meter enables the indication of the current time.

    6. INTERFACE RS-485 N30U programmable digital meters have serial links in RS-485 stan- dards for the communication in computer systems and with other de- vices fulfilling Master function. An asynchronous communication cha- racter protocol MODBUS has been implemented on the serial link. The transmission protocol describes ways of information between devices through the serial link.
