Frequently used programming steps.
Reading a weight value:
1. Check the D12…D15 bits of ‘PT113EI Output to PLC Input 3
rd
Dword’.
2. If there is no error, read a weight value (gross, net or tare).
Zero Calibration procedure:
1. Check the low byte of Calibration Status. it should be decimal '1' to start adjustment.
2. Write ‘Adjust Zero Calibration’ command and apply New CMD to start Zero calibration.
3. Check the low byte of Calibration Status, it is decimal '3' during the zero calibration process.
4. The low byte of Calibration Status changes to decimal '1' at the end of the Zero calibration.
5. If the low byte of Calibration Status is '9', check the high byte of Calibration Status to
understand the calibration error.
Span Calibration procedure:
1. Check the low byte of Calibration Status. it should be decimal '1' to start adjustment.
2. Write ‘Adjust Span Calibration’ command after writing test weight values to 1
st
Dword, then
apply this command with New CMD to start Span calibration.
3. Check the low byte of Calibration Status, it is decimal '4' during the span calibration process.
4. The low byte of Calibration Status changes to decimal '1' at the end of the Span calibration.
5. If the low byte of Calibration Status is '9', check the high byte of Calibration Status to
understand the calibration error.
