6. SETTING THE ZERO AND THE WEIGHT

In order to make the scale's settings, press the internal setting key on the

scale's main board, which is accessed from the scale bottom (as shown in the section 'Connections'), when the scale is in the basic work mode or when it is displaying dashes during the initial zero.

If you press the calibration button at this time, the scale zeroes the scale with

the deadweight currently on the platform. This process may be instant or it may

Page 21

GBS-ECO-MF-V02

take several seconds if the weight is not stable at that time. During the time that the scale takes to zero, the reading of the zero's value in internal points is displayed. The scale then automatically sets a known weight value and shows the following display:

At this time, the weight value detected by the scale is shown, even if it is an incorrect value because it has not been adjusted (in this case '0.000', there is no weight on the platform).

Place the known weight on the platform and enter the value of the known standard weight (2/3 of the full-scale value is recommended). After entering the

value, press the key. It is possible to correct the weight by pressing the

key. The scale displays the reference values and the reference zero for several seconds, which it will save as references of the setting time. It will then show the real value of the weight set:

To return to the basic work mode, press the calibration button again. The

scale's zero and weight will now be set.

7. COMMUNICATION PROTOCOL

TPV 0 (Protocol $):

To operate with this protocol, the value 'TYPE 0' must be selected in the 'TPV CONEX' option. The possible values in this option are 'TYPE A' and 'TYPE B'. The next step is to select the transmission mode: 'WAITING' (awaiting request), 'AUTOM' (automatic) or 'MANUAL'.

TYPE A:

Awaiting request

This communication mode is compatible with the basic work modes WeightTare, Levels and Part Counting.

Communication format:

Computer

request

Scale answer

<$>(0x24, 36d)

Scale answer:

<STX> - Character 0x02, 2d <ST> - Status byte whose value is obtained by adding the

weight flags' status (0x08 if zero weight, 0x20 if stable weight, 0x02 if net weight, and 0x01 if gross weight) to 0x20.

<PPPP.PPP> - Value of the weight in ASCII and with 8 bytes,

including the weight's decimal point and the '-' sign when the net weight is negative. The weight field is left-justified with blank spaces (0x20, 32d). When the weight is out of range, dashes are sent (character 0x2d, 45d) occupying

all 8 bytes of the weight field. <CR> - Character 0x0d, 13d. <ETX> - Character 0x03, 3d.

Page 23

GBS-ECO-MF-V02

Automatic

This communication mode is compatible with the basic work modes Weight-

Tare, Levels and Part Counting.

The scale automatically sends the weight with the trace described in the

section 'Awaiting request'.

Manual

This communication mode is compatible with the basic work mode Weight-

Tare.

When the key is pressed, if the weight is stable, the scale sends the

weight with the trace described in the section 'Awaiting request'. If the weight is not stable, the scale starts a stable weight capture sequence. When the weight becomes stable, the scale sends the weight. If the weight does not stabilize within a preset time (2 seconds), the weight is not sent and the scale will display an unstable weight error (Error 14).

TYPE B:

Awaiting request

This communication mode is compatible with the basic work modes Weight-

Tare, Levels and Part Counting.

The scale can perform a series of functions if it receives a certain request:

a.-] Scale reset:

Communication format:

Computer

Page 24

GBS-ECO-MF-V02

Scale answer:

0000000 - 0x30, 48d <CR> - Character 0x0d, 13d.

b.-] Autozero request:

Communication format:

Computer

request

Scale answer

<%>(0x25, 37d)

The scale performs an autozero, and, upon completing the process (with or without carry out autozero), sends the string:

0000000<CR>

Scale answer:

0000000 - 0x30, 48d <CR> - Character 0x0d, 13d.

c.-] Disabling / enabling the transmission beep:

Communication format:

Computer

request

Scale answer

<'>(0x27, 39d)

The scale enables or disables the beep

each time it sends a trace. The scale does

not answer this request. When the scale is

turned on, the beep process is disabled by

default.

Page 25

GBS-ECO-MF-V02

d.-] Weight request:

Communication format:

Computer

request

Scale answer

<$>(0x24, 36d)

The scale transmits the weight with the

following trace:

<PPP.PPP><CR>

Scale answer:

<PPP.PPP> - Value of the net weight with 7 bytes including the

decimal point and left-justified with zeros (0x30) <CR> - Character 0x0d.

• Special cases of this protocol:

d.1.-] Net weight zero and stable: Sends '0000000<CR>'

d.2.-] Net weight over or under: Sends 'AAAAAAA<CR>'

d.3.-] Net weight in range and stable: Sends 'PPP.PPP<CR>' (the value of the weight with 7 bytes including the decimal point and justified with zeros on the left.

d.4.-] Net weight in range, stable and negative: Sends the string described in section 'd.2.-]'.

d.5.-] Net weight in range and unstable: The scale retains the weight request indefinitely until it becomes stable, when the scale operates as described in section 'd.3.-]'.

• Transmission started by the scale at the beginning

a.-] When the scale is powered on and the initial sequence is completed, it indicates that it is ready by sending the sequence: '0000000<CR>', described previously.

Page 26

GBS-ECO-MF-V02

Automatic

This communication mode is compatible with the basic work modes Weight-

Tare, Levels and Part Counting.

After selecting this option, the automatic transmission protocol type is

chosen. The possible values are: 'Await request' or 'Manual'. The scale automatically sends the weight depending on the trace selected:

Await request trace: <PPP.PPP><CR>

<PPP.PPP> - Value of the weight with 7 bytes including the decimal

point and justified with zeros (0x30) on the left. If the

weight is out of range (over or under) or there is a

negative net weight, a string composed of 7 characters

'A' (0x41, 65d) is sent. <CR> - Character 0x0d.

Manual transmission trace: <STX><ST><PPP.PPP><CR>

<STX> Character 0x02, 2d. <ST>

Tare status. The possible values are: 'blank' (0x20, 32d)

if the weight is gross, 'T' (0x54, 84d) there is a tare, and

'F' (0x46, 70d) if there is a fixed tare. <PPP.PPP> - Value of the weight with 7 bytes including the decimal

point and justified with (0x30) on the left. If the weight is

High, Low or negativ, it sends: <AAAAAAA>. <CR> - Character 0x0d, 13d.

Manual

This communication mode is compatible with the basic work mode Weight-

Tare.

When the key is pressed, if the weight is stable, the scale sends the weight with the corresponding trace. If the weight is not stable, the scale starts a stable weight capture sequence. When the weight becomes stable, the scale sends the weight. If the weight does not stabilize in a preset time (TIME LIMIT), the weight is not sent and the scale displays an unstable weight error (Error 14).

The trace used in this format is that described in the Automatic transmission format with Manual transmission trace.

Page 27

GBS-ECO-MF-V02

After sending the weight, the scale waits for an answer before the end of the preset time (TIME OUT). If no answer is received when this time expires, the scale displays 'Error 9'. If the character 'ACK ' is received before the time has elapsed (TIME OUT), the scale beeps, displays the indication 'TXD OK' for 2 seconds and finally beeps again, returning to the weight mode. If a negative answer is received, 'NAK', the scale displays 'Error 10'.

TPV 1 (IBM Protocol):

In order to operate with the IBM protocol, you must select the value ''TYPE 1'' in the ''CONEX TPV'' option.

This communication mode is compatible with the basic work modes WeightTare, Levels and Part Counting.

There are 2 control functions from the TPV, Weight Request and Autozero Request. The scale only has 2 possible answers: Weight Transmission and Invalid Result.

Weight request

TPV Scale

Weight Transmission trace: <S><SP><SP><PPPPPPPPP><UU><CR><LF>

Invalid Result trace: <S><I><SP><CR><LF>

The scale must answer in less than 5 s. The weight trace if the weight is stable, has varied since the last request, the weight is in range, and the scale is not autozeroing. If these conditions are not met, the scale returns the Invalid Result trace.

If the weight is unstable, it waits a maximum time of 3 seconds. If after this time it is not stable it sends invalid result.

Page 28

GBS-ECO-MF-V02

Weight Transmission trace:

<S> - Character 0x53, 83d. <SP> - Character 0x20, 32d. <PPPPPPPPP> - Weight with 9 bytes, without decimal point and left-

justified with zeros (0x30).

<UU> - Units. The possible values are: (G_), (KG), (OZ),

and (LB). The scale always sends (G_). <CR> - Character 0x0d, 13d. <LF> - Character 0x0a, 10d.

Invalid Result trace:

<S> - Character 0x53, 83d. <I> - Character 0x49, 73d. <SP> - Character 0x20, 32d. <CR> - Character 0x0d, 13d. <LF> - Character 0x0a, 10d.

Autozero request

TPV Scale

<T> - Character 0x55, 85d. <CR> - Character 0x0d, 13d. <LF> - Character 0x0a, 10d.

When the scale receives this request, it performs an Autozero request. At the end of the sequence, irrespective of whether or not the scale has been able to Autozero, it sends the 'Invalid Result' trace in reply.

TPV 2A (UNIWELL-ICL Protocol):

In order to operate with the Uniwell-ICL protocol, you must select the value ''TYPE 2A'' in the ''CONEX TPV'' option.

Page 29

If the TPV receives the frame <STX><ID><PPPPP><BCC><ETX> (weight in range), it resends the same frame to the scale so that it can compare the frame sent and received.

When the scale has received the frame for comparison, it returns:

- NAK (0x15, 21d), if there is an error in the reception.

- ACK (0x06, 6d), if the frame received does not match the frame sent.

- CR (0x0d, 13d), if the frame received matches the frame sent.

End of sequence.

This accepts 4 commands:

TPV Scale

W<CR>

Weight: returns the weight with units and the scale's status: <LF><PP.PPP><UU><CR><LF><'S'hh><CR><ETX>

TPV Scale

S<CR>

Scale status: <LF><'S'hh><CR><ETX>

TPV Scale

Z<CR>

Returns the scale's status after performing an autozero: <LF><'S'hh><CR><ETX>

TPV Scale

H<CR>

Weight in high resolution: returns the scale's status: <LF><'S'hh><CR><ETX>

TPV Scale

Others

Unrecognized command: <LF>?<CR><ETX>

ETX - Character (0x03, 3d). LF - Character 0x0a, 10d. CR - Character (0x0d, 13d). PP.PPP - Value of the weight with decimal point and left-

justified with zeros (0x30). UU - Measuring units in upper case (kg, oz, lb...). 'S'hh - Character 'S' + 2 status bytes. ? - Character 0x3F.

Coding of the status bytes:

Bit First status byte Second status byte

0 1 – Scale in movement 1 – Weight under

0 – Weight stable 0 – No Weight under

1 1 – Scale at zero 1 – Weight over

0 – Weight <> zero 0 – No Weight over

2 1 – Ram Error 1 – Rom Error

0 – No Ram error 0 – No Rom error

3 1 – Eeprom Error 1 – Calibration failure

0 – No Eeprom error 0 – Calibration OK

4 Always 1 Always 1

5 Always 1 Always 1

6 Always 0 1 – There is a third status byte

0 – Last byte

7 Always 0 Always 0

TPV 8 (DICENTRO Protocol):

TPV Scale

Page 33

GBS-ECO-MF-V02

W - Character 0x57, 87d. STX - Character 0x02, 2d. PPPPP - Value of the weight (5 bytes) in ASCII without

decimal point, without sign and justified with zeros

(0x30d). CR - Character (0x0d, 13d). '?' - ASCII character (question mark, 3F Hex.). STATUS - 1 status byte:

- Bit 7: 1 if in key zero.

- Bit 2: 1 weight under.

- Bit 1: 1 weight over.

- Bit 0: 1 weight not stable.

TPV 9 (ELZAB Protocol):

The trace format is the following:

TPV Scale

<'-'><LF>

Answer in Basic Protocol: <S><SP><PP.PPP><CR><LF>

Answer in Extended Protocol (await request): <ESC><E><S><PP.PPP<CR><LF>

1. Request from the TPV to the scale:

ESC - Character 0x1B. M - Character 0x4D. ETX - Character (0x03, 3d). '-' - Character 0x82. LF - Character 0x0a, 10d.

Page 34

GBS-ECO-MF-V02

2. Answer from the scale in Basic Protocol and pulsator: S - Sign: blank space (20h) if the result is zero, and

'minus' (2Dh) if the result is less than 0. SP - Blank space: 20h. PP.PPP - Value of the weight (6 bytes) with decimal point,

no sign and justified with blank spaces (0x20d). CR - Character (0x0d, 13d). LF - Character (0x0a, 10d).

3. Answer from the scale in Extended Protocol (await request) and pulsator: ESC - Character 0x1B.

E - Stability: 'S' if the result is stable, and 'U' if the

result is unstable (weight negative, over or under, always 'U').

S - Sign: blank space (20h) if the result is zero, and

'minus' (2Dh) if the result is less than 0.

PP.PPP - Value of the weight (6 bytes) with decimal point,

no sign and justified with blank spaces (0x20d). CR - Character (0x0d, 13d). LF - Character (0x0a, 10d).

TPV 10 (VECTRON Protocol):

The scale continuously sends the weight when the TPV enables (set) the DTR signal. As the Eco Multifunction scale does not have DSR, the TPV's DTR is input through RxD of the scale's RS-232 communication connector. This requires a special cable.

The trace of the message sent by the scale to the TPV is the following: <ID (2 bytes)><SEPARATOR (2 bytes)><DATA (6 bytes)><Units (2

bytes)><CR><LF>

Page 35

GBS-ECO-MF-V02

ID - 'IF' (0x53, 0x49), if the weight is out of range,

over or under.

- 'S ' (0x53, 0x20), if the weight is stable.

- 'SD' (0x53, 0x44), if the weight is unstable. SEPARATOR - ' ' (0x20, 0x20), two blank spaces. DATA - Weight in grams, with max. 6 characters, right-

justified and filled with zeros to complete all 6

spaces. If the weight is out of range, 6 dashes are

sent. UNITS - 'g ' (0x67, 0x20), grams. CR - Character (0x0d, 13d). LF - Character 0x0a, 10d.

8. LIST OF POSSIBLE ERRORS

ERROR NUMBER CAUSE

TIMEOUT – Zero and reference capture time exceeded.

NAK reception in comunications ‘TYPE 0’, ‘TYPE B’ and key.

UNSTABLE WEIGHT.

INCORRECT CHECKSUM– Series E2prom read error.

EEPROM WRITE.

INVALID DATA.

DATA TOO LARGE – If the set weight is less than 20000 net points. If a Plu greater than 100 is requested. If an item is programmed with a value greater than that allowed.

DATA TOO SMALL – If the set weight is greater than 85000 net points. If Plu 0 is requested. If there is any scale parameter with an incorrect value.

NULL DATA – If the set weight entered is 0.

WEIGHT OUT OF RANGE – Tare out of range.

INCORRECT WEIGHT – If the set weight entered is not a multiple of the step.
