Digital Outputs Command
Note
It allows control to the outputs status in

See Section 2.10 on page 24 .
Bit a 1: output is closed; Bit a 0: output is open.
Setting bit 15 to 1 on the PLC, PROFIBUS takes control of all the outputs, even if they are in different modes.
Status Register

Bit No. Description
Bit 0 Cell Error
Bit 1 A/D Converter Malfunction
Bit 2 Maximum weight exceeded by 9 divisions
Bit 3 Gross weight higher than 110% of full scale
Bit 4 Gross weight beyond 999999 or less than -999999
Bit 5 Net weight beyond 999999 or less than -999999
Bit 6 —
Bit 7 Gross weight negative sign
Bit 8 Net weight negative sign
Bit 9 Peak weight negative sign
Bit 10 Net display mode
Bit 11 Weight stability
Bit 12 Weight /-¼ of a division around ZERO
Bit 13 Writing error
Bit 14 —
Bit 15 —
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.
