11.1 Code Download
Code Download Utility
A code download may be recommended to upgrade the fieldbus firmware. A download utility
program is used to perform the upgrade. A code download also updates other files necessary for
proper operation; specifically, new versions of the Standard Dictionary and Device Description files
are loaded on the host computer. These files are compatible with the new code.
A PC-based application is available to download new firmware into a Logix 3400IQ digital positioner.
Refer to the documentation accompanying that application for instructions.
CAUTION A code download can be performed on an active live network. Prepare the
control loop by blocking in the final control device to a safe state. The positioner will be off-
line for about 30 minutes. Save the present configuration before downloading. When the download is
complete, the positioner will revert to its default settings.
The Effects of a Code Download on a Device
The effects on a device (as a result of the download) are that all configuration data in the device, with
the exception of calibration data, is cleared. This includes:
Device and block tags
Block parameters
The function block schedule
Link object, trend object, and VCR configurations
The network schedule
This requires the user to reconfigure the block tags and the control system, and then download the
configuration (FBAP file) to the device and other device on the network.
The device ID may appear differently on the network, due to differences between the new and older
software versions. The device may appear as a new device since the NI configuration system uses
the device ID as the key identification variable for a device. The Logix 3400IQ LEDs will blink RRRG
during the code download because communications to the controller board is interrupted. This will
return to normal blink when the process is completed.
