TRANSMISSION
SERIAL PORT 1
Data can be transmitted from the serial port 1 in
4
ways, depending on Configuration during the PcMO step.
Continuous weight transmission (“ ALL” )
The instrument transmits in a continuous way the weight value:
With Baud rate 9600 one can obtain up to 8 transmissions per second.
With Baud rate 4800 one can obtain up to 7 transmissions per second.
Weight transmission at each weighing operation
(“ StAb” )
Each time a weight on the scale becomes stable, a communication string is transmitted on the serial port 1
(see TRANSMISSION FNS)
For non legal for trade instruments:
The transmission takes place when the weight is stable and the net weight is
>
0.
For more weight transmissions, the net weight most go back to ->0<- first.
Weight transmission requested from an external device in 485 (“O ndE” and 485 )
In this case the IPB50 must receive one of the three following commands from an external device before
transmitting:
OnDE 485
Read command: "READ" + CR + LF "CCREAD" + CR + LF
Answer: see below
TARE command: "TARE" + CR + LF "CCTARE" + CR + LF
Answer: "ACK" ASCII (06H) if command is understood
Nothing or "NACK" ASCII(15H) if command is not understood
Zero command: "ZERO" + CR + LF "CCZERO" + CR + LF
Answer: ACK" ASCII (06H) if command is understood
Nothing or "NACK" if command is not understood
Relay 1 Enabling Setpoint: “STP1XXXXX” + CR + LF "CCSTP1XXXXX” + CR + LF
Answer: ACK" ASCII (06H) if command is understood
Nothing or "NACK" if command is not understood
Relay 2 Enabling Setpoint: “STP2XXXXX” + CR + LF “CCSTP2XXXXX” + CR + LF
Relay 1 Disabling Setpoint: "SP1OXXXXX" + CR + LF "CCSP1OXXXXX" + CR + LF
Relay 2 Disabling Setpoint "SP2OXXXXX" + CR + LF "CCSP2OXXXXX" + CR + LF
Nota: SP1O and SP2O if not necessary if setpoint without hysteresis.
The Read command transmits the weight, while the TARE and ZERO commands are the same as those
available on the keyboard.
With Baud rate at 9600 and at 4800 one can carry out up to 7 requests per second.
The CC command is a number code (between 00 and 99) that identifies the IPB50 when protocol 485 is
selected.
If the request takes place cyclically, it is possible to acquire the weight with a 3,5 Hz frequency.
