5.4.4 Individual Characteristic

N30U meters can recalculated the measured value into any value thanks to the implemented individual characteristic function. The individual characteristic rescales the input signal measured according to the set characteristic. The way of the individual characteristic interaction on the meter operation has been presented on the fig. 9.

Fig. 9. Action of the Individual Characteristic.

The user can introduce maximally twenty functions through giving intervals and expected values for successive points.

The programming of the individual characteristic consists on the definition of the number of points which the input function will be linearized by. On must remember that the number of linearizing functions is of one

23

smaller than the number of points. Next, one must program successive points by giving the measured value (Hn) and the expected value corresponding to it, – value which has to be displayed (Yn). The graphic interpretation of the individual characteristic is presented on the fig. 10.

Rys. 10. Individual Characteristic.

During the function approximation, one must remember that for the approximation of functions strongly differing from the linear characteristic, higher the number of linearizing segments, smaller the error related to the linearization.

If measured values are smaller than H1, recalculations will be made on the base of the first straight line calculated on the base of points

(H1,Y1) an (H2,Y2). However, for values higher than Hn (where n – the last declared measured value) the value to display will be calculated on the base of the last assigned linear function.

Note: All introduced points of the measured value (Hn) must be arran-

24

ged in the increasing sequence, such to preserve the following dependence:

H1<H2<H3...<Hn

If the above is not fulfilled, the individual characteristic function will be automatically switched off (will not be realized) and a diagnostic flag will be set in the status register.

5.4.5 Alarm types

The N30U meter is equipped with 2 alarm outputs with NOC contact

(make contact) and two alarm outputs with NOC/NCC contact (make and break contact) (option). Each of alarms can work in one of the six modes. The work of alarms in modes is presented in the fig. 12: n-on, noff, on, off. Two remaining modes: h-on and h-off mean suitably, always switched on and always switched off. These modes are destined for the manual simulation of alarm states.

a) n-on b) n-off c) on d) off

Fig. 11. Alarm Types: a) n-on, b) n-off c) on d) off.

25

Caution !

l

In case of alarms of n-on, n-off, on, off types the write of PrL>PrH will cause the alarm switching off. l

In case of a measuring range overflow, the reaction of the relays is compatible with written PrL, PrH, tYP parameters. In spite of the displayed overflow, the meter still carries out the measurement.

l

The meter controls currently the value of the introduced parameter at the moment. In case when the introduced value overflows the upper range given in the table 1, the meter will make automatically the change into the maximal value. Similarly, in case when the introduced value overflows the lower change range given in the table 1, the meter will make automatically the change into the minimal value.

5.4.6 Display Format

The N30U meter adapts automatically the display format (precision) to the value of measured quantity. So that the function could be fully used, one must choose the format 0.0000, then the meter will display the measured value with the possible highest accuracy. This function does not operate for the time display, where the format is set automatically. The current time (mode HOUr) is displayed in the 24 hours’ format, in the shape hh.mm, where hh – current hour, and mm – current minute.

Caution: Remember that the display with a higher resolution is not always desired, it can conduct to a deterioration of the indication stability.

5.5. Manufacturer’s Parameters

Standard settings of the N30U meter are presented in the table 7.

These settings can be restored by means of the meter menu through the choice of the option Set from the menu Ser.

6. INTERFACE RS-485

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

6.1. Connection Way of the Serial Interface

The RS-485 standard allows to a direct communication of 32 devices on a single serial link of 1200 m long (at baud rate 9600 b/s). For the

28

connection of a higher quantity of devices, it is necessary to apply additional intermediate-separating systems (e.g. PD51 converter).

The lead out interface line is presented on the fig. 4. To obtain a correct transmission, it is necessary to connect lines A and B in parallel with their equivalents in other devices. The connection must be made through a shielded wire. The wire shield must be connected to the protection terminal in the nearest possible neighbourhood of the meter

(connect the shield only in a single point to the protection terminal).

The GND line serves to the additional protection of the interface line at long connections. Then, one must connect GND signals of all devices on the RS-485 bus.

To obtain the connection to the computer, a RS-485 interface card or a suitable converter is indispensable, e.g. PD51 or PD10.

The connection way of devices is shown on the fig. 12

Fig. 12. Connection Way of the RS-485 interface

The designation of transmission lines for the card in the PC computer depends on the card producer.

6.2. Description of the MODBUS Protocol

Implementation

The implemented protocol is in accordance with the PI-MBUS-300 Rev

G of Modicon Company specification.

Set of the serial link parameters of N30U meters in MODBUS protocol: l

work mode: RTU z ramk¹ w formacie 8n2, 8e1,

8o1, 8n1, l

maximal response time: 100 ms.

The parameter configuration of the serial link consists in the settlement of the baud rate (bAUd parameter), device address (Addr parameter), and the format of the information unit (prot parameter)

Notice: Each meter connected to the communication network must have: l

unique address, different from addresses of other devices connected to the network, l

identical baud rate and type of information unit.

7. UPDATING OF SOFTWARE

Function enabling updating of software from the computer of the PC with software LPCon was implementation in meter N30U (from version of software 1.10) in the realization with the interface RS485. Free software LPCon and update files are accessible on the side www.lumel.

com.pl . The connected to the computer convertor RS485 is required on USB to the updating, e.g.: the convertor PD10.

a) b)

42

Pic. 13. Program view: a) LPCon, b) updating of software

Warning! Before doing update, currently settings of meter should be saved by program LPCon, because when software is updated default settings of meter are restored.

After starting LPCon’s software COM port, baudrate, transmission mode and adress should be set. It can be done in Options. Then, N30U meter should be selected from Device. Push icon Load to read and save current settings. Open window Lumel Updater (LU) – figure 13b from Updating->Updating of devices firmware. Push Connect. Update progress is shown in Messages section. Text Port opened appear after correctly opened port. Putting meter in update’s mode can be done in two ways: remote from LU (with settings from LPCon – port, baudrate, transmission mode and adress) or by turning power on while button

pressed (updating by standard communication parameters - baudrate 9600 kb/s, mode 8N2). AL1 led signals that device is ready for update. LU will show message „Device found” with name and current version of firmware. Using button ... a valid file should be selected.

If the file is correct, message File opened will show. Send button should be pressed. During firmware update AL1-AL4 leds indicate process progress. If firmware update is successful device starts normal operation and message Done and update duration will show. Close LU and go to Restoration of manufacturer’s parameters. Select checkbox and press Apply button. Next press Send button to restore previously read parameters. Current firmware version can be checked when meter is power on.

Warning! Power loss during firmware update could result permanent meter damage!
