- TRANSMISSION WHEN THE PRINT KEY IS PRESSED “Prin.Std”, “PrinEX” parameter
The instrument communicates the weight data through the serial port when the ENTER key is
pressed (except for in the TOTALIZER mode where one should press the MODE key).
For non approved instruments:
The transmission takes place if the weight is stable and the net weight is > 0.
Reenabling the transmission depends on how the “rEACt” step has been set in the SET-UP
environment (passing by zero of the NET weight, weight instability or always).
For approved instruments:
The transmission takes place if the weight is stable and the net weight is > 20 divisions.
Reenabling the transmission depends on how the “rEACt” step has been set in the SET-UP
environment (passing by zero of the NET weight, weight instability or always).
The data is transmitted using the standard string (Prin.Std) or the extended string (PrinEX); see the
“TRANSMISSION PROTOCOL” section for the description of the two strings.
- TRANSMISSION IN RS 485 SERIAL MODE “485” parameter
The protocol is the same as the transmission upon request (ondE parameter), except that the
instrument responds only if its machine code is the one requested (before the request the machine
code must be put, I.E. 00READ<CRLF>).
If a broadcast address command (99) is received no answer is given. If the command is correct it is
executed anyways.
- TRANSMISSION IN RS 485 MODBUS (See special manual)
- TRANSMISSION IN RS 485 PROFIBUS (See special manual)
- CONTINUOUS TRANSMISSION “ALL.Std”, “ALL.Ext and ALL.MAX” parameter
- This mode is used for interfacing to the PC, remote displays and other devices which request a
constant updating of the data independently from the weight stability.
The instrument transmits data with each converter read operation:
- With Baud rate at 9600 one can obtain up to 10 transmissions per second.
- With Baud rate at 4800 one can obtain up to 8 transmissions per second.
The transmission works with weight <, =, > 0 with approved or unapproved instrument.
The data is transmitted using the standard string (ALL.Std) or the extended string (ALL.EXt); see
the “18.5 TRANSMISSION PROTOCOL” section for the description of the two strings.
ALL.MAX transmission protocol is advisable for application in which a high frequency transmission
is requested. (up to 250TX/sec with baud rate equal to 155200), the weught is transmitted in
hexadecimal format (ex : 03E8 = 1.000g), without decimal point..
Nota: the data transmission frequency is depending of the configured filter.
To obtain 250TX/sec, you should configurate the filter to F.F.400 (SetuP-> ConFIG -> Param.->
StAbiL)
- TRANSMISSION ON STABILITY “StAb.St” and “StAb.EX” parameter
Each time a weight on the scale becomes stable, a communication string is transmitted on the PC
serial port.
For non approved instruments:
- The transmission takes place if the weight is stable and the net weight is > 10 divisions.
- Reenabling the transmission depends on how the “rEACt” step has been set in the SET-
UP environment (passage by zero of the NET weight or instability of the NET weight of 10
divisions; by choosing “always” it works upon instability).
For approved instruments:
- The transmission takes place if the weight is stable and the net weight is > 20 divisions.
