2071 Panelmeter for serial communication - 1

• Serial inputs RS-232 and RS-485 • 6-digit processor-based LED display • Input galvanically isolated • Front panel keys can be read • Power supply 85..240 VAC or 24 VDC/ 24 VAC • Front panel protection IP65 Number of meters in one Data Addresses: Baud rate: General: Display Operating temperature Terminals Power supply Front panel protection Case dimensions Weight The panelmeter 2071 is designed for serial communication. It uses the simple Nokeval SCL protocol where only the address, value and check sum are sent. The panelmeter has both the serial inputs RS-232 and RS-485 as a standard. The serial bus is galvanically isolated from the processor and the power supply. In the configuration mode you can set the address, baud rate and the type of number value that you want to appear on the display after power connection. In industrial environments use of the addressable serial signal RS-485 is always recommended. 31 displays can be connected to one bus and by using a serial data converter (721R), another 31 displays can be added on. The maximum distance of the bus is 1 km. Serial input RS-232 only accepts one display connected to the bus the maximum distance being 15 m. Front panel protection is IP65. The panelmeter series 2000 is very flexible and easy to modify by changing input cards for different kinds of sensors, such as temperature sensors, pulse sensors, serial inputs etc. The modification does not require any calibration. The optional cards are the same for all the instruments in this product family. Each panelmeter type has its own datasheet. Separate field enclosures can be supplied for 1 to 3 panel-meters. The 2071 is also available in the field display series, model 2800-2071. Technical specifications: Input: serial signal RS-485 and RS-232, selection with terminal connections, galvanically isolated Max. distancies: 1000 m with RS-485 20 m with RS-232 loop: 1 with RS-232; 1-31 with RS-485 8 characters, 1 stop, no parity 0...99 300, 600, 1200, 2400, 4800, 9600 and 19200 baud 6 digits, bright red (or green) LED, digit height 14.5 mm, brightness selectable -10..+60 °C removable, wire 2,5 mm2 85...240 VAC or 12..32 VDC/ 24VAC IP65 with a rubber gasket 48 x 96 x 115 mm (DIN1/8) 240 g Type Serial output card RS232/485 Power supply 230VAC or 12..32 VDC/ 24 VAC The panelmeter is also available with a green LED display: please specify 2071GR in the order code.

2071 Panelmeter for serial communication - 2

Communication parameters Baud rate: 300, 1200, 2400, 4800, 9600 or 19200 8 data bits, None parity, 1 stop bit. Protocols The panelmeter 2071 and the field display 2071 can be controlled by two alternative protocols: either Nokeval SCL or Ascii. The protocol is selected in the configuration menu. Ascii protocol is very simple and there is no address involved, so every display will show the same reading. A detailed presentation of Ascii protocol is included in the manuals of the instruments. SCL protocol The SCL command packet consists of the actual command added by some control bytes....
