Fieldbus
Shows the fieldbus type, address and status of the optional Fieldbus interface.
It also gives the possibility to study the contents in selected parts of the instrument
memory (data to and from the fieldbus master). The function is very useful for
advanced fault finding in case of problems with the fieldbus communication.
The contents of the output memory (data to the fieldbus master) are displayed in
hexadecimal form at the six lines of the display. On each line eight byte values are
displayed, preceded by 'o' for output and the address of the first byte.
The contents of the input memory (data from the fieldbus master) are displayed in
hexadecimal form at the six lines of the display. On each line eight byte values are
displayed, preceded by 'i' for input and the address of the first byte.
Keys F1 (Prev.) and F2 (Next) are used to step in the memory.
Use key F3 (Input/Output) to change between display of output and input memory.
See chapter 7 ‘Communication’ section ‘Fieldbus interface’ for details on fieldbus data
mapping.
