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 with two lines on the display. On each line four 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 with two lines on the display. On each line eight byte values are
displayed, preceded by 'i' for input and the address of the first byte.
The ‘+’ and ‘
−
’ keys are used to step forwards /
backwards in the memory.
Use key ‘
↵
’ to change between display of output and input
memory.
When entering the fieldbus menu is a line showing
fieldbus type and address shown. Press the ‘+’ key to
display the fieldbus status. Press ‘+’ key again and

See chapter ‘Communication’ section ‘Fieldbus and
EtherNet/IP Data Definitions’ for details on fieldbus data
mapping.
The figure on the right shows some examples of how the
fieldbus diagnostics display might look.
EtherNet/IP
The menu give the possibility to study the contents in used instances (data to or from
the scanner). The function is very useful for advanced fault finding in case of problems
with the communication.
The content in the selected instance are displayed in hexadecimal form with two lines
on the display. On each line four byte values are displayed, preceded by the address of
the first byte. For producing instances 102 and 103 the amount of data is according to
the actual number of data blocks used (setup).
The first screen show selected instance. If a scanner is connected to the shown
instance Active is show else is Inactive shown. No data is shown if the instance is
inactive.
The ‘+’ and ‘
−
’ keys are used to step the displayed
addresses forwards / backwards.
Use key ‘
↵
’ to’ to display next instance (100 – 101 –
102 – 103 – 100 etc).
See chapter ‘Communication’ section ‘Fieldbus and
EtherNet/IP Data Definitions’ for details on fieldbus
data mapping.
