Rockwell Automation 57C435 Processor Module, AutoMax - Manual (Page 23)

4Ć3
All Processors in all racks on a network containing only 57C404A
modules can be accessed and loaded through the single
connection at the local rack. Note that you do not need to
establish a network connection through the ONĆLINE menu to
load an operating system over a network. The loading procedure
is always performed through Load Operating System on the
Commands menu.
To load the operating system over a network(s) connected to the
local rack through 57C404A Network Communication modules,
select Load Operating System" from the Commands menu
again. Select N" to load the operating system over the
network(s). Then select A" to load the standard operating system
or E" to load the Ethernet operating system. At this point, you
havethreechoices:
Ć
enter A" to load the operating system to all drops on all
networks that do not already have an operating system.
When the procedure is complete, the system will print the
drop numbers that have not been loaded to the screen.
Ć enter O" to load the operating system to all drops on all
networks, regardless of whether the Processors in those
drops already have an operating system. This option will
write over all operating systems that exist in all Processors on
all networks. It will also require that you reĆload any tasks that
exist on those Processors. Note that this option requires the
password to be entered.
Ć enter the slot number of the Network module representing
the network you want to load over. If you select this option,
you will also beableto chooseto load theoperating system
to one drop, all drops on this network where there is no
operating system, or to load the operating system to all
drops on this network regardless of whether there is an
existing operating system. This third option will require that
you reĆload any tasks that exist on the Processors whose
operating systems were overĆwritten. If you choose the third
option, thesystem will print thedrop numbers that havenot
been loaded to the screen. The password is required to
overĆwrite any existing operating system.
Enter your choice and <CR>.
4.2 Accessing Processor Ports
All Processor ports in the rack except the port
PROGRAMMER/PORT B" in theleftmost Processor areavailableto
the user. A port can be accessed using the OPEN statement (OPEN
PORTA or OPEN PORTB) in BASIC tasks running on thespecific
Processor on which the port is located. Refer to JĆ3675 for more
information on the OPEN statement.
Refer to figure 4.1 for information about the OPEN statement SETUP
parameter for the AutoMax Processor. Defaults are indicated by (D).
