3. GETTING STARTED
3.3 Bus Power ON
Turn on the power of the host and the bus and also the
power for the AXF. Where the AXF is equipped with
an LCD indicator, first all segments are lit, then the
display begins to operate.
Using the host device display function, check that the
AXF is in operation on the bus.
The device information, including PD tag, Node
address, and Device ID, is described on the sheet
attached to the AXF. The device information is given
in duplicate on this sheet.

If no AXF is detected, check the available address
range. If the node address and PD tag are not specified
when ordering, default value is factory set. If two or
more AXFs are connected at a time with default value,
only one AXF will be detected from the host as AXFs
have the same initial address. Separately connect each
AXF and set a different address for each.
3.4 Integration of DD
If the host supports DD (Device Description), the DD
of the AXF needs to be installed. Check if host has the
following directory under its default DD directory.
594543\000B
(594543 is the manufacturer number of Yokogawa
Electric Corporation, and 000B is the AXF device
number, respectively.)
If this directory is not found, the DD of the AXF has
not been included. Create the above directory and copy
the DD file (0m0n.ffo, 0m0n.sym) (m, n is a numeral)
into the directory. ‘0m’ in the file name shows the
device revision, and ‘0n’ shows the DD revision. If
you do not have the DD or capabilities files, you can
download them from our web site:
http://www.yokogawa.com/fld
Once the DD is installed in the directory, the name and
attribute of all parameters of the AXF are displayed.
Off-line configuration is possible by using capabilities
files.
AXF has two capabilities levels, “1” and “2”.
Select “Capabilities level = 1” when the AXF doesn’t
have LC1(PID function) option.
Select “Capabilities level = 2” when the AXF has
LC1(PID function) option.
The capabilities level defines the kind and the number
of function blocks that can be used.
The table below shows the relation.

3.5 Reading the Parameters
To read AXF parameters, select the AI block of the
AXF from the host screen and read the OUT param-
eter. The current selected signal is displayed. Check
that MODE_BLOCK of the function block and
resource block is set to AUTO, and change the signal
input and read the parameter again. A new designated
value should be displayed.
