Rockwell Automation 57C620 AutoMax Programming Executive Version 3.8 - Manual (Page 89)

5Ć33 Using the System Configurator
that all tasks in the rack will be deleted when you load the AutoMax
operating system to the Processor(s) in the rack. To ensure that the
values of any tunable variables will be maintained in their
respective tasks, you should save all application tasks in the
rack that contain tunable variables back to the personal
computer from the rack (see 14.4) after you have finished tuning
variables, and before you load the new operating system. If you
are loading a more recent version of the operating system, you may
need to reĆcompile your application tasks using the corresponding
Programming Executive software before downloading them to the
rack.
UDC modules use nonĆvolatile Flash memory to store their operating
systems and UDC application tasks, so you will need to reĆload the
UDC operating system only when enhancements become available
or when a UDC module in the rack is replaced. Note carefully that all
tasks in the UDC module will be deleted when you load the UDC
operating system to that particular UDC module.
See Appendix T for problems that can occur when you load
operating systems.
Types of AutoMax Operating Systems
The AutoMax operating system, which oversees the operation of the
AutoMax Processors and the execution of application tasks, is
provided in three versions: 6010/6011ĆStandard, 6010/6011ĆEthernet,
and 7010ĆStandard. The 6010/6011ĆStandard or 6010/6011Ć Ethernet
operating system can be loaded onto M/N 57C430A or 57C431
Processors. In order to use the Ethernet functions that allow
communication over Ethernet using the TCP/IP protocol, an Ethernet
Network Interface module (M/N 47C440) must be installed in the rack
and the Ethernet operating system must be used. The Ethernet
operating system is also required if any of the following functions are
used in BASIC tasks: READVAR%, WRITEVAR%, FINDVAR!, and
CONVERT%. The 7010 Ć Standard operating system, which supports
all of the Ethernet functions, must be used with the M/N 57C435
Processor.
When you load the AutoMax operating system to the Processor
modules in the rack, you will be prompted for which operating
system you want to load for the M/N 57C430A and M/N 57C431
Processors. The 7010ĆStandard operating system will be loaded to all
M/N57C435 Processors. Note that if you have loaded the 6010/6011Ć
Standard operating system and then attempt to use the Ethernet
communication functions in an application task, the Processor will
display error code 4A on its LEDs when you try to put the task into
run.
The 6010/6011ĆEthernet operating system will occupy approximately
134K of RAM, leaving 122K available for application tasks on the M/N
57C430A Processor. The 6010/6011ĆStandard operating system will
occupy approximately 119K of RAM, leaving 137K available for
application tasks on the M/N 57C430A Processor. The M/N 57C431
makes 300K available for application tasks, regardless of which
operating system is used. The M/N 57C435 also makes 300K
available for application tasks.
Time Required to Load Operating Systems
The operating system(s) will be loaded at the maximum baud rate
available for the Processor being used. If you are using 6010/6011
and 7010 Processors in the same rack, make sure that the leftmost
Processor is a 7010 (M/N 57C435) Processor. This will allow the
