40 SCT Weight Transmitter Operator’s Manual
Status Register
Bit 13 (writing error) rises if the PLC tries to write a value out of a parameter’s permitted interval. In this case the
writing has no effect and the previous parameter value is maintained.
Possible Command To Send To The Command Register
Commands are sent only once; to reassert it write the value 0 to the Command register and then the command
again
Real Calibration Commands (With Sample Weight)
The instrument calibration can be changed via PROFIBUS.
To correctly set the sample weight, consider the value of the division module (e); e.g. if you want to set the value to
100kg and the division value is 0.001, set the register value to 100000 (you remove the decimal points form the
value that would be 100.000 with decimals).
To perform the edit calibration procedure, it needs to unload the system and zero-setting the displayed weight value
with the command 100 “Zero-setting for calibration” of Command Register. Then, put a sample weight onto the
system, write the correct known weight value to the “Sample Weight for calibration” register; to save in memory
the sample weight value, send the command 101 “Sample weight storage for calibration”.
