[ See explanation of numbers in Sec. 4.4 below. The xxxxxxxx is like a serial no. that is unique to each
unit manufactured. ]
If the AV550G is not detected on the Fieldbus, check its address setting and also check the available
free addresses on the Fieldbus. Unless the PD tag and node address are specified at order time, then
the factory defaults above will apply. If two or more AV550G with factory default settings are connected
to the Fieldbus, then, since their address settings are the same, only one will be detected. Connect
them one at a time and assign them different addresses.
4.4 Installation of DD
If the host supports DD (Device Description), then the DD file of the AV550G needs to be installed.
Check if the host has the following directory under its default DD directory.
594543\0401
(Here 594543 is the manufacturer ID of Yokogawa Electric Corp., and 0401 is Yokogawa’s
device ID number for the AV550G.)
If this directory does not yet exist, then the AV550G DD file has not been installed.
Create the directory, and copy the AV550G DD file (which has a file name like “0m0n.ffo,0m0n.sym”
where m and n are numbers) to the directory.
When the DD file is installed, you will be able to display all the parameter names and attributes of the
AV550G. You can also use the capability file (CFF) to perform offline configuration.
Both the DD file and the capability file will be available for download from the Yokogawa web site. You
can confirm the URL with your Yokogawa rep.

Be sure to use the DD file that matches the AV550G Device Revision no.
4.5 Reading Device Parameters
Try reading AV550G parameters. Select the AI block of the AV550G on the screen of the host, and
read a parameter such as OUT (representing the output current). Confirm that the function block
resource block MODE_BLOCK is AUTO.
4.6 Continuous Record of Values
If the host can continuously record parameter values, use this function to record some values.
Depending on the Host software, you may have to change the update interval of Publish (which
periodically sends the updated parameter value to the bus).
