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
19
GBS-ECO-MF-V02
Downloaded from www.Manualslib.com manuals search engine
 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:

 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 Weight-
Tare, Levels and Part Counting.

Communication format:

Computer Scale answer

request

<$>(0x24, 36d)

<STX><ST><PPPP.PPP><CR><ETX>

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.

21
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 Scale answer

request

<#>(0x23, 35d)

The scale restarts and, upon completing

the process, sends the string:

 Scale answer:

0000000 - 0x30, 48d

<CR> - Character 0x0d, 13d.

b.-] Autozero request:

Communication format:

Computer Scale answer

request

<%>(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 Scale answer

request

<'>(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.

23
GBS-ECO-MF-V02
Downloaded from www.Manualslib.com manuals search engine
 d.-] Weight request:

Communication format:

Computer Scale answer

request

<$>(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.

 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.

25
GBS-ECO-MF-V02
Downloaded from www.Manualslib.com manuals search engine
 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 Weight-
Tare, 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
<S><CR><LF>
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.

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.

 This communication mode is compatible with the basic work modes Weight-
Tare, Levels and Part Counting:

TPV Scale
ENQ
NAK, if there is an error in the reception.
NULL, if the weight is unstable.
ACK, if the weight is zero or is not zero but has varied
since the last request.
CAN, if the weight has not varied since the last request.

ENQ - Character 0x05, 5d.

NACK - Character 0x15, 21d.
NULL - Character 0x00, 0d.
ACK - Character 0x06, 6d.
CAN - Character 0x18, 24d.

When the scale sends 'ACK' to the TPV:

TPV Scale
DC1
NAK, if there is an error in the reception.
<STX><ID><PPPPP><BCC><ETX>, if the weight is
in range.
<STX><ID><00000><BCC><ETX>, if the weight is
not in range.

DC1 - Character 0x11, 17d.

NACK - Character 0x15, 21d.
STX - Character 0x02, 2d.
ID (weight in - Scale type depending on the full-scale value. The
range) scale always sends (0x69).
ID (weight not in - Scale type depending on the OR full-scale value
range) with 0x10. The scale always sends (0x79).
PPPPP - Value of the weight in ASCII without decimal
point and left-justified with zeros (0x30).
00000 - Five zeros in ASCII (0x30).
BCC - XOR of all of the frame's characters except STX
and ETX.
ETX - Character (0x03, 3d).

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.

TPV 2B (UNIWELL-W Protocol):

 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>

33
GBS-ECO-MF-V02
Downloaded from www.Manualslib.com manuals search engine
 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.
