Note

When editing numeric values, press to allow numeric mode change entry, then press or to change the digit selected. Press or to increment or decrement the value of the ﬂashing selected digit.

Press to save the value entered and return to the level above.

The EDP command set can be used to configure the 120 indicator using a personal computer, terminal, or remote keyboard. Like Revolution, EDP command configuration sends commands to the indicator EDP port; unlike Revolution, EDP commands can be sent using any external device capable of sending ASCII characters over a serial connection.

EDP commands duplicate the functions available usin

g the indicator front panel and provide some functions not otherwise available. EDP commands can be used to simulate pressing front panel keys, to configure the indicator, or to dump lists of parameter settings. See Section 5.0 on page 23 for more information about using the EDP command set.

3.1.3 Front Panel Configuration

The 120 indicator can be configured using a series of menus accessed through the indicator front panel when the indicator is in setup mode. Table 3-1 summarizes the functions of each of the main menus.

Graduations. Specifies the number of full scale graduations. The value entered must be in the range 1–100 000 and should be consistent with legal requirements and environmental limits on system resolution.

To calculate GRADS, use the formula, GRADS = Capacity / Display Divisions. Display divisions for primary and secondary units are specified on the FORMAT menu.

Zero track band. Automatically zeroes the scale when within the range specified, as long as the input is within the configured zero range (ZRANGE parameter). Selections are ± display divisions. Maximum legal value varies depending on local regulations.

Zero range. Selects the range within which the scale can be zeroed. The 1.9% selection is ± 1.9% around the calibrated zero point, for a total range of 3.8%. Indicator must be at standstill to zero the scale. Use 1.9% for legal-for-trade applications.

Motion band. Sets the level, in display divisions, at which scale motion is detected. If motion is not detected for 1 second or more, the standstill symbol lights. Some operations, including print, tare, and zero, require the scale to be at standstill. Maximum legal value varies depending on local regulations.

If OFF is selected, ZTRKBN should also be set to OFF.

Overload. Determines the point at which the display blanks and an out-of-range error message is displayed. Maximum legal value varies depending on local regulations.

Sample rate. Selects measurement rate, in samples per second, of the analog-to-digital converter. Lower sample rate values provide greater signal noise immunity.

Digital filtering. Selects the digital filtering rate used to reduce the effects of mechanical vibration from the immediate area of the scale.

Choices indicate the number of A/D conversions that are averaged to obtain the displayed reading. A higher number gives a more accurate display by minimizing the effect of a few noisy readings, but slows down the settling rate of the indicator. See Section 7.6 on page 34 for more information on digital filtering.

Digital filter cutout sensitivity. Specifies the number of consecutive readings that must fall outside the filter threshold (DFTHRH parameter) before digital filtering is suspended. If NONE is selected, the filter is always enabled.

5.0 EDP Commands

Note

The 120 indicator can be controlled by a personal computer or remote keyboard connected to the indicator EDP port. Control is provided by a set of EDP commands that can simulate front panel key press functions, display and change setup parameters, and perform reporting functions. The EDP port provides the capability to print configuration data or to save that data to an attached personal computer. This section describes the EDP command set and procedures for saving and transferring data using the EDP port.

5.1 The EDP Command Set

The EDP command set includes key press commands, mode commands, reporting commands, the RS special function command, and parameter setting commands.

The indicator responds to sending the message

OK. The OK response verifies that

the command was received and has been executed. (Pressing

ENTER after processing a valid EDP

command repeats the previous command.) If the command is unrecognized or cannot be executed, the indicator responds with

identifier

The RS (reset configuration) command can be used to restore all configuration parameters to their default values. Before issuing this command, the indicator must be placed in test mode (press and hold setup switch for approximately three seconds to enter test mode).

This command is equivalent to using the DEFLT

ction on the TEST menu. See Section 7.7 on

fun page 35 for more information about test mode and using the TEST menu.

All load cell calibration settings are lost when the RS command is run.

5.1.4Parameter Setting Commands

Parameter setting commands allow you to display or change the current value for a particular configuration parameter (Tables 5-3 through 5-8).

Current configuration parameter sett

ings can be displayed in either configuration mode or normal mode using the following syntax:

command<ENTER>

Most parameter values can be changed in configuration mode only. Use the following command syntax when changing parameter values:

command=value<ENTER>

where value is a number or a parameter value. Use no spaces before or after the equal (=) sign. If you type an incorrect command or value, the display reads

??.

Changes to the parameters are saved as they are entered but typically do not take effect until you exit configuration mode.

5.2 Saving and Transferring Data

Note

Connecting a personal computer to the 120 EDP port allows you to save indicator configuration data to the PC or to download configuration data from the PC to an indicator. The following sections describe the procedures for these save and transfer operations.

5.2.1 Saving Indicator Data to a Personal Computer

Configuration data can be saved to a pers onal computer connected to the ED P port. The PC must be running a communications program such as PROCOMMPLUS

communications wiring and EDP port pin assignments. When configuring the indicator, ensure that the values

menu match the baud rate, bits, and parity settings configured for the serial port on the PC. Set the PRNDES parameter to EDP.

To save all configuration data, place the indicator in configuration mo command to the indicator. The 120 responds by sending all configuration parameters to the PC as ASCII-formatted text.

5.2.2 Downloading Configuration Data from PC to Indicator

Configuration data saved on a PC or floppy disk can be downloaded from the PC to an indicator. This procedure is useful when a number of indicators with similar configurations are set up or when an indicator is replaced.

T o download configuration data, connect the in configuration mode and use the PC

PC to the EDP port as described in Section 5.2.1. Place the indicator

communications software to send the saved configuration data to the

indicator. When transfer is complete, calibrate the indicator as described in Section 4.0 on page 21.

. See Section 2.2.1 on page 5 for information about serial

set for the BAUD and BITS parameters on the SERIAL

de and send the DUMPALL EDP

• Calibration settings are included in the configuration data downloaded to the indicator. If the receiving indicator is a direct replacement for another 120 and the attached scale is not changed, recalibration is not required.

• When downloading configurations that include changed

serial communications settings, edit the data file to place the serial communications changes at the end of the file. Communication between the PC and indicator will be lost once the indicator receives settings for baud rate (BAUD parameter) or data bits and parity (BITS parameter) that do not match those configured for the PC.

6.0 Print Formatting

Note

The 120 print format can be edited to specify the format of the printed output when the

PRINT key is

pressed or when a KPRINT EDP command is received.

Each print format can be customized to include

up to 300 characters of information, such as company name and address, on printed tickets. You can use the indicator front panel (PFORMT menu), EDP commands, or the Revolution® configuration utility to customize the print format.

6.1 Print Formatting Commands

Table 6-1 lists commands you can use to format the print format. Text included in the format string must be enclosed in quotation marks (hex 22). T characters can include any ASCII character that can be printed by the output device.

Command Description

6.2 Customizing Print Formats

The following sections describe procedures for customizing the print format using the EDP port or the front panel (PFORMT menu).

6.2.1 Using the EDP Port

With a personal computer, terminal, or remote keyboard attached to the 120 EDP port, you can use the EDP command set to customize the print format string.

To view the current setting of the print format, type WWPF (to values) then press sending the current configuration for the print format:

Use the WWPF or WPF EDP command followed by an equals sign (=) and ze string.

The following example shows the commands used to define printer.

7.5 Conversion Factors for Secondary Units

Note

The 120 has the capability to mathematically convert a weight into many different types of units and instantly display those results with a press of the

UNITS key.

Secondary units can be specified on the FORMAT

u using the SECNDR parameter, or by using EDP

men commands.

• To configure secondary units using the front nel menus, use the Table 7-4 to find the

pa conversion multiplier for the MULT parameter. For example, if the secondary unit is short tons, set the MULT parameter to 000050.

Next, use the MULEXP parameter to set the decimal point position. In the example above,

e conversion factor for pounds to short tons is

th actually 0.0005 (2000 lb x 0.0005 = 1 tn). Use

and keys to shift the decimal point to

the show a value of 0.00050.

Another example: If the primary unit is ounces and the

secondary unit is grams, the conversion factor is 28.3495. To enter this value using the menus, first enter 283495 for the MULT parameter, then use the MULEXP parameter to adjust the decimal point to 28.3495.

• To configure secondary units using EDP comma

nds, use the Ta bl e 7-4 to find the

conversion value for the SEC.MULT and

and. For example, if the primary unit is

comm pounds and the secondary unit is short tons, send the following EDP command to set the multiplier for the secondary units.

SEC.MULT= 0.00050<CR>

• Units of weight other than those listed in Table 7-4 cannot be directly specified as primary or secondary units on the 12 unlisted units of weight, specify NONE on the UNITS parameter.

Ensure that the secondary decimal point position is set appropriately for the scale

capaci converted value requires more digits than are available, the indicator display will overflow.

For example, if the primary units are short tons, secondary units are pounds, and the secondary decimal point is set to 8888.88, the indicator will overflow if 5 tons or more are applied to the scale. With 5 tons applied, and a conversion factor of 2000, the secondary units display needs five digits to the left of the decimal point to display the 10000 lb secondary units value.

7.6 Digital Filtering

The 120 uses averaged digital filtering to reduce the effect of vibration on weight readings. Adjustable threshold and sensitivity functions allow quick settling by suspending filter averaging, allowing the weight reading to jump to the new value. Digital filtering parameters are set using the CONFIG menu.

7.6.1 DIGFLx Parameters

The first three digital filtering parameters, DIGFL 1, DIGFL2, and DIGFL3, are configurable filter stages that control the effect of a single A/D reading on the displayed weight. The value assigned to each parameter sets the number of readings received from the preceding filter stage before averaging.

The overall filtering effect can be expressed by adding the values assigned to the three filter stages:

DIGFL1 + DIGFL2 + DIGFL3

For example, if the filters are configured as DIGFL1=4, DIGFL2=8, DIGFL3=8, the overall filtering effect is 20 (4 + 8 + 8). With this configuration, each A/D reading has a 1-in-20 effect on the displayed weight value. Setting the filters to 1 effectively disables digital filtering.

7.6.2 DFSENS and DFTHRH Parameters

The three digital filters can be used by themselves to eliminate vibration effects, but heavy filtering also increases settling time. The DFSENS (digital filter sensitivity) and DFTHRH (digital filter threshold) parameters can be used to temporarily override filter averaging and improve settling time:

• DFSENS specifies the number of consecutive scale readings that must fall outside the filter threshold (DFTHRH) before digital filtering is suspended.

• DFTHRH sets a threshold value, in display divisions. When a specified number of consecutive scale readings (DFSENS) fall outside of this threshold, digital filtering is suspended. Set DFTHRH to NONE to turn off the filter override.

7.6.3 Setting the Digital Filter Parameters

Fine-tuning the digital filter parameters greatly improves indicator performance in heavy-vibration environments. Use the following procedure to determine vibration effects on the scale and optimize the digital filtering configuration.

1. In setup mode, set all three digital filters (DIGFL1, DIGFL2, DIGFL3) to 1. Set DFTHRH to NONE. Return indicator to normal mode.

2. Remove all weight from the scale, then watch the indicator display to determine the magnitude of vibration effects on the scale. Record the weight below which all but a few readings fall. This value is used to calculate the DFTHRH parameter value in Step 4.

For example, if a heavy-capacity scale produces vibration-related readings of up to 50 lb, with occasional spikes to 75 lb, record 50 lb as the threshold weight value.

3. Place the indicator in setup mode and set the digital filters (DIGFLx) to eliminate the vibration effects on the scale. (Leave DFTHRH set to NONE.) Reconfigure as necessary to find the lowest effective values for the DIGFLx parameters.

4. With optimum values assigned to the DIGFLx parameters, calculate the DFTHRH parameter value by converting the weight value recorded in Step 2 to display divisions:

threshold_weight_value / DSPDIV

In the example in Step 2, with a threshold weight value of 50 lb and a display division value of 5lb: 50 / 5lb = 10DD. DFTHRH should be set to 10DD for this example.

5. Finally, set the DFSENS parameter high enough to ignore transient peaks. Longer transients (typically caused by lower vibration frequencies) will cause more consecutive out-of-band readings, so DFSENS should be set higher to counter low frequency transients.

Reconfigure as necessary to find the lowest effective value for the DFSENS parameter.
