The procedures to do an on-line update are written in the AADvance
Configuration Guide, Rockwell Automation reference 553633.
On-line modifications must follow the end users' MOC process as required by
the applicable industry safety standards. On-line modifications must include any
specific checks recommended by Rockwell Automation for the product.
Important Note: For Releases 1.3 you can change the I/O module
configuration with an on-line update without having to stop the running
application. However, if you are still using an earlier product release the I/O
module configuration cannot be changed with an on-line update.
Changes that affect the system's ability to respond safely, or that may
cause other plant disruption shall not be performed on-line unless alternate
protection measures can be implemented for the duration of such
modifications.
Physical Installation
The installation environment is a potential source of common cause failure,
therefore it is vital that compatibility of the equipment with the environment is
known. The environment for these purposes includes the prevailing climatic,
hazardous area, power, earthing and EMC conditions. In many cases, there will
not be a single installation environment. Elements of the system may be
installed in differing locations; in these cases, it is important to know the
environment for each location.
You must use installation and commissioning procedures that comply
with the applicable international or local codes and standards.
The AADvance controller equipment (base units and modules) is designed for
use when it is installed upright, that is with the base units in a vertical plane
and the ventilation slots on the modules at the top and bottom. This
orientation is essential to ensure non-forced air cooling is effective and the
controller meets the specified MTBF of the modules. This rule applies to all
installations regardless of ambient temperature and any additional forced air
cooling that may be applied.
