A11.1 Benefits of Software Download
This function enables you to download software to field devices via a F
software.
Typical uses are to add new features such as function blocks to existing devices, and to optimize existing field
devices for your plant.
A11.2 Specifications
Current Draw (Steady-state): 15mA (max)
Current Draw (Software Download state): 24mA
(max)
Current during FlashROM blanking time:
Max. 24 mA additional to steady-state
current
Based on Fieldbus Foundation Specification
Download class: Class 1
NOTE
Class 1 devices can continue the specified
measurement and/or control actions even
while software is being downloaded to them.
Upon completion of a download, however, the
devices will be reset internally to make the new,
downloaded software take effect, and this will
halt fieldbus communication and function block
executions for about one minute.

A11.3 Preparations for Software
Downloading
For software downloading, you need to prepare the
following:
• Software download tool
• Software for downloading file for each of the
target field devices
For the software download tool, use only a program
developed for that purpose. For details, see the
software's User's Manual. For information about
updates of software binary files for field devices and
how to obtain them, visit the following web site.

CAUTION
Do not hook up the software download tool to a
fieldbus segment while the plant is in operation,
as it may temporarily disturb the communication.
Always connect the tool before starting
operation.
