5.4.3 Loading Operating Systems
AutoMax Processor modules and UDC modules require operating
systems to be loaded before they can function in the rack. The
AutoMax Programming Executive software includes the operating
systems for the AutoMax Processors. Operating systems for the
Universal Drive Controller (UDC) modules are included only on
the separatelyĆpurchased DPS drive software. This software is
assumed to be loaded onto the personal computer if it is
required. The UDC operating system file also contains the operating
systems for the Power Module Interface (PMI) Processors. Once the
UDC operating system has been loaded to the UDC module, the PMI
operating system is automatically loaded to the PMI Processor(s)
upon powerĆup.
Before you can go online with any rack in the system, the operating
system for the AutoMax Processor(s) must be loaded to the local rack
from the personal computer on which you have installed the AutoMax
Programming Executive software. If you are running Version 3.5 of
the Programming Executive software, and the local rack already
contains Version 2.0 or later of the AutoMax operating system, you
can communicate with any rack that is on the same network as this
local rack. However, you will be able to use only those features that
are supported by the operating system which exists on the
destination rack. For example, before you can load the UDC
operating system to the UDC module(s) in a rack, Version 3.6 of the
AutoMax operating system must be loaded to the AutoMax
Processor(s) in that rack. If you are running an earlier version of the
Programming Executive software, you will not be able to
communicate with a rack that contains the AutoMax Version 3.6
operating system either by direct connection or over the network.
The leftmost AutoMax Processor in the rack will check for
compatibility between the AutoMax OS and the UDC OS. If you
replace a UDC with another UDC that already contains an OS that 's
incompatible, the new UDC will be disabled and its OS OK" LED will
turn off.
Precautions in Loading the AutoMax Operating System
Normally, when the operating system is loaded to the AutoMax
Processors in a rack, the AutoMax operating system currently on the
Processors (if any) is written over. However, it is possible that the
operating system in the rack is a later version than the operating
system contained in the Programming Executive software you are
using. In this case, the Programming Executive will be unable to
establish communication with the rack in order to load the new
AutoMax operating system until you erase the existing operating
system. The procedure for erasing the operating system for all of the
AutoMax Processors in a rack is described in section 5.4.4.
The situation described above cannot occur when loading the
operating system to UDC modules since communication is
established first with the AutoMax Processor in the rack first and then
with the UDC module rather than the UDC module directly. The
existing operating system on a UDC module (if any) will be written
over when you load any UDC operating system to that module.
AutoMax Processor modules have onĆboard battery backup, so you
will need to reĆload the AutoMax operating system only when
enhancements become available, when you change the password
for the rack using the PWOS.EXE utility described in 9.2.1, or when
an AutoMax Processor module in the rack is replaced. Note carefully
