CAUTION
The current dissipation of the target field device temporarily increases immediately after a
download due to erasing of the FlashROM’s contents. Use a Fieldbus power supply which has
sufficient capacity to cover such increases in feed current.
CAUTION
Upon the completion of the activation(*1), the target fieldbus device performs resetting internally.
The reset breaks communication with the field device and stops function block execution.
*1 Processing which automatically replaces the downloaded software in the software download
processing
CAUTION
Do not turn off the power to a field device or disconnect the download tool during a download or
activation. The device may fail as a result. Be careful about the noise on the Fieldbus link. If the
fieldbus is noisy, the downloading may take a very long time or fail.
A6.5 Download Files
Download files have the following filenames (with the filename extension of ”.ffd”). If a device type
is AXG, “0016”, and AXW, “0017”. Take care to choose the correct download file for the target
field device:
“594543” + “Device Family” + “_” + “Device Type” + “_”
+ “Domain Name” ” + “_” +”Software Name” + “_”
+”Software Revision” + ”.” + “ffd”
(For example, the name of the download file for the AXG may have the following name:)
5945430016_0016_AXG4A_ORIGINAL_R101.ffd
The software name is “ORIGINAL” or “UPDATE”. The former indicates an original file and the
latter an update file. Whenever performing a download to update the device revision, be sure to
obtain the original file. In general, device revision is updated when a parameter or block is added.
