5 Commissioning

The meaning of indicator LEDs and the operating concept are described in Chapter 4.

5.1 Data Backup/Power Failure

The calibration data and parameters as well as all configuration and interface data are stored in a non-volatile (EAROM) memory. Unauthorized data changing can be prevented by an access code. Additional write protection is provided for calibration data and parameters (CAL switch, see Chapter 5.1.1).

5.1.1 CAL Switch

The CAL switch protects the calibration data / parameters against unauthorized access. When the CAL switch is in 'open' position, the calibration data and parameters can be changed

using the PC program or via the Profibus connection. With the CAL switch in the 'closed' position, the calibration data (e.g. dead load, Span) and Parameters (e.g. measure time, zero tracking etc.) cannot be changed.

The CAL switch is located under a cover that can be opened by means of a knife.

For ’legal-for-trade’ applications, set the CAL switch (4) to the left position and seal the cover.

5.1.2 Factory Settings

Section 5: Commissioning

5.2 Switching on the Instrument

The instrument can be put into operation and calibrated using a PC with the VNC program (on the CD packed with the instrument), an Internet Browser or the ConfigureIt program.

5.2.1 Resetting the Instrument, Activating 'DHCP'

The instrument can be reset using a pin with a diameter of 1.0 mm (e.g. paper clip).

By actuating during approx. 1 second, the program is re-started. When actuating during approx. 3 seonds, 'DHCP' is activated in the instrument (independent of the previous settings). This ensures that a valid address for identification of the instrument in the network can be assigned to the instrument by a server.

05/11 29 51209 Revision 2

5.2.2 Searching the Instrument in the Network Using 'IndicatorBrowser'

The address can be determined using the 'IndicatorBrowser' (in a directory on the CD-ROM packed with the instrument) program.

Install and start the 'IndicatorBrowser'.

When the instrument is connected to a network, it is “default” in the DHCP mode, i.e. an address is assigned to it by the server. This address, e.g.

172.24.21.85, can be determined using the ‘IndicatorBrowser’ program.

Section 5: Commissioning

5.3 Operation Using a PC

5.3.1 Operation Using the VNC Program

VNC stands for 'virtual network computing' and is a program for remote operation of computers. The program distinguishes between the VNC server and VNC client (viewer). The server program is part of the instrument software. The client program (viewer) must be installed and executed on the PC to be used for operating the instrument.

For direct operation using the VNC program, the IP address (extended by :1) must be specified when you run the program, e.g. 172.24.21.85:1.

The address range of the controlling PC can be limited in the instrument; see Chapter 5.6.5. The operator interface of the VNC program appears:

05/11 30 51209 Revision 2

5.3.2 Operation Using Internet Browser

With the Internet browser, the IP address must be filled in. Example:

5.4 Calibration

5.4.1 Calibration using weights, mV/V or load cell data can be done using the VNC program. During calibration, the instrument must be set to gross weight display (reset tare, if necessary).

For a ’legal-for-trade’ application, set the mode under -[Calibration]-[Param] to [W&M] before starting calibration; see Chapter 5.4.20. Select [New] to go to the maximum capacity [Max] (see chapter 5.4.7), select the scale interval and determine the dead load. Now calibrate the maximum capacity by applying a calibration weight, in mV/V or with load cell data. After determining the test value, the menu can be closed as described in Chapter 5.4.18, in order to save the new settings. Calibration data can be protected by the CAL switch (see Chapter 5.1.1), which must be sealed in the closed (write-protected) position for ‘legal-for-trade’ applications.

Dead load: Calculation of the equivalent input voltage in mV/V The input voltage in mV/V equivalent to the dead load can be calculated by using the dead load rather than the maximum capacity in the formula specified above. Normally, calculation of the dead load (scale without load/empty hopper) is not necessary. Subsequent dead load correction (as described in Chapter 5.4.15) can be used for later redetermination of the dead load, when the scale/hopper is empty.

Example: Load cell(s) with rated output of 2mV/V at nominal load of 2000 kg, dead load 500 kg, load cell supply voltage 12 VDC

5.4.15 Subsequent Dead Load Correction

If the hopper/platform weight changes by an amount that is higher than the zero-setting range; e.g., due to dead load reduction, dead load increase or mechanical changes, the functions for automatic zero tracking and manual zero setting no longer work. To view the range which is already utilized by

zero tracking or zero setting, select [Calibration] and press ; this also activates 10-fold increased resolution of the weight value. Press again to return to the previous state:

Current zero setting: 0.123 kg

If the entire zero-setting range is already utilized, you can still correct the dead load (CAL switch must be open) without affecting other calibration data/parameters.

To do this, select -[Calibration]-[Modify] and determine the dead load with [Dead load at]-[by load] (see Chapter 5.4.9).

Range selection is controlled by three parameters under -[Calibration]-[Param].

WP A/Calibration

Range mode

Multiple range

Select [Multiple range] or [Multi-interval] Range limit 1 1000 kg Switch point from range 1 to 2 Range limit 2 2000 kg Switch point from range 2 to 3

Multiple range scale (cl. III, or cl. I and II single range scale with variable scale interval) With [Range mode] = [Multiple range], the scale has up to 3 ranges with different resolutions. The switch points [Range limit 1] and [Range limit 2] are the range limits. As soon as the gross weight exceeds range 1, the next higher range with the next higher interval becomes valid (1->2->5>10->20->50->100->200). When reducing the weight, the interval of the previous range is kept. When the gross weight is <= 0.25 d of range 1 and the scale is stable and not tared, the scale returns to range 1 with the corresponding interval.

Multi-interval scale (cl. III, or cl. I and II single range scale with variable scale interval) With [Range mode] = [Multi-interval], the scale has up to three ranges with different resolutions. Each range has the corresponding interval. Unlike [Multiple range], switching the interval is also triggered by weight reduction; i.e., when the weight drops below the range limits.

During calibration, the multiple range/multi-interval function is always switched off. The weight display header (VNC) includes the current range (R1, R2, R3), Max, Min and d (or e with legal-for-trade instruments) (Example: multiple range scale in range 2):

Section 6: SMA Protocol

6 SMA Protocol

6.1 General

The protocol of the 'Scale Manufacturers Association' (SMA) provides a simple access to the scale. It can be used for reading data, or for executing functions.

The RS-485 interface is used. Fixed interface settings are 8 bits, no parity and 1 stop bit. The commands to the transmitter are printable ASCII characters starting with <LF> = 0A hex and

ending with <CR> = 0D hex. The instrument sends a reply on each received command after approx. 100 µs. With commands that wait for stability of the weight value, the reply can be delayed by the waiting time.

6.2 Description of Used Symbols

All characters used in this protocol are printable ASCII characters. Characters <CR> <LF> <SPACE> and <ESC> are excepted. < > The symbols < and > are used to put communication fields and non-printable ASCII

characters into brackets. These symbols are never part of any communication

message. <LF> A data set starts with a line feed character (line feed = 0A hex). <CR> A data set ends with the carriage return character (carriage return = 0D hex). ‘_’ <space> The underscore or space character is used to mark an ASCII space character (20

hex). <ESC> The 'escape' character (1B hex) is used to cancel a command. ‘!’ An ASCII exclamation mark (21 hex) is used for communication errors. ‘:’ An ASCII colon is used as a field delimiter. ‘-’ ASCII minus sign (2D hex) ‘?’ An ASCII question mark (3F hex) is used for unknown or non-supported commands. ‘c’ Command character. All printable ASCII characters are permitted. <s><r><n> Scale status indicator characters; ASCII letters or spaces <m><f> For details, see Chapter 6.6.1. <r><e> Scale diagnostics indicator characters; upper case ASCII letters or spaces. <c><m> For details, see Chapter 6.6.4. <xxxxxx.xxx> Weight data including minus sign (right-adjusted) and a decimal point (if any). If

necessary, leading spaces are introduced with a leading zero before the decimal

point. The entire field is always 10 characters long. With some error states, the field

is filled up with minus signs '-'. Examples: <_ _ _ _ _0.000>; <_ _ _ _11.120>; <_ _ _ _ -1.000>; <- - - - - - - - - -> <yyyyyy> Text field of printable ASCII characters; for transporting scale information. The field

has max. 25 characters. <uuu> Abbreviation of the used unit. The field is always 3 characters long; it is left-adjusted

and filled up with spaces.

Section 7: Fieldbus Interface

7 Fieldbus Interface

7.1 Fieldbus Interface Protocol

The interface works with an 8-byte write window and an 8-byte read window. The fieldbus exchanges its data cyclically with each slave. This means: In each cycle, 8 bytes are written and 8 bytes are read, also if the data content is unchanged. The fieldbus protocol ensures the data transport between the fieldbus master and the 2 x 8-byte data windows. The interface protocol runs under the fieldbus and manages the access to a multitude of different data.

05/11 80 51209 Revision 2

Section 7: Fieldbus Interface

7.1.1 Write Window (Input Area)

Data transmission from the master to the slave (PR 5220) is in this window. The first four bytes are used only for writing a data value. The register number is in byte 5.

Bytes 6 and 7 contain bits in direct access independent of the write data. The command is executed after a 0-1 transition of the corresponding bit.

Byte 0 Write data: MSB Byte 1 " Byte 2 " Byte 3 Write data: LSB Byte 4 Read_Value _Select Byte 5 Write_Value _Select Byte 6 Direct control bits Byte 7 Direct control bits

7.1.2 Read Window (Output Area)

Data transmission from the slave (PR 5220) to the master is in this window. The first four bytes are used for reading a data value.

The register number of data is mirrored in byte 4 by the write window, when data is available.

Bytes 5, 6 and 7 contain status bits independent of the read data.

Byte 0 Read data: MSB Byte 1 " Byte 2 " Byte 3 Read data: LSB Byte 4 Read_Value _Selected Byte 5 General system bits:

- Write_Active

- power_fail

- analog error..

Byte 6 Status bits Byte 7 Status bits

.

7.1.3 Reading and Writing Data

The number of data exceeds the size of the read/write window by far. For this reason, data is addressed with

Write_Value_Select a

nd

Read_Value_Select.

To do this, the first six bytes of the write window and the first five bytes of the read window are required. These can be used by the master to write data in PR 5220: e.g., a limit value is set to 100kg. The master can also read out weight values or other data from the PR 5220. For this purpose, the write and the read window are always required. Safe data exchange is ensured by a write and a read procedure. For reading status bits, and for writing direct control bits, however, no procedure is required. The general system bits and the status bits are always provided and need not be requested. The direct control bits are also available continuously.

Procedure for reading data:

1. Writing the register number as

2. Waiting, until the

_Select

in b

Read_Value _Selected

yte 4

of the write window.

Read_Value _Select in byte 4

in b

yte 4

of the read window is equal to the

of the write window (e.g. net weight).

Read_Value

3. Now the value is available in bytes 0 to 3. Procedure for writing data:

1. Waiting, until

2. Writing the value in

Write_Active = 0

bytes 0 to 3

in the read window (ready to receive new data).

.

3. Writing the register number in byte 5 (Write_Value_Select).

4. Waiting, until
