Table 15-3 – Expanded command list
(1) Write this command after writing values to 1
st
Dword (Output) then apply this command with New CMD.
(2) To access the related value, read 1
st
Dword (Input).
Programming steps of frequent used commands
Reading a weight value:
1. Check the B12…B15 bits of ‘FT-112(D) Panel Output to PLC Input 2
nd
Dword’.
2. If there is not any error, read the weight value ( gross, net or tare ).
Zero Calibration procedure
1. Check the Bit-0 of Calibration Status. it should be '1'(set) to start adjustment.
2. Write ‘Adjust Zero Calibration’ command and apply New CMD to start Zero calibration.
3. Check the Bit-1 of Calibration Status. it is '1'(set) during zero calibration process.
4. The Bit-0 of Calibration Status changes to '1'(set) at the end of the Zero calibration.
5. If the Bit-3~Bit-10 of Calibration Status is '1'(set), check the description to understand the calibration
error.
Span Calibration procedure
1. Check the Bit-0 of Calibration Status. it should be '1'(set) 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 Bit-1 of Calibration Status. it is '1'(set) during span calibration process.
4. The Bit-0 of Calibration Status changes to '1'(set) at the end of the Span calibration.
5. If the Bit-3~Bit-10 of Calibration Status is '1'(set), check the description to understand the calibration
error.
