BENTLY 3500/24 Cylinder pressure monitor
The device and controller configuration parameters used when
NBH is initiated can be examined via the Network I/O Teach
(NIOT) command.
Note that certain arguments will be passed (through MPU
registers) to the loaded program. See the NBO command
description for examples and further explanation.This is a string of characters. Up to 2 strings may be
specified, usually the name of the file to boot and a
optional string (string #2). String #2, if specified, is
passed to the booted file. To specify string #2 a delimiter
must be used to differentiate from string #1 (boot
filename). Both character strings default to a null
character string
NBO is used to load an operating system
control program from
the server into memory and give control to it (execute). The load
and execution address of the file is specified via the configuration
parameters. The device and controller configuration parameters
used when NBO is initiated can be examined via the Network I/O
Teach (NIOT) command.
NBO uses primarily the BOOTP, RARP, and TFTP protocols to load
the boot file. Refer to the DARPA Internet Request for Comments
RFC-951, RFC-903, and RFC-783, respectively, for the description of these protocols. You may skip the BOOTP phase (address
determination and bootfile selection) by specifying the IP addresses
(server and client) and the boot filename; the booting process
would then start with the TFTP phase (file transfer) of the boot
sequence.
IP addresses of "0" are special in that these addresses
always force
a BOOTP/RARP phase to occur first. If all (client and server) of the
IP addresses are known/specified, the TFTP phase occurs first. If
this phase fails in loading the boot file, the BOOTP/RARP phase is
initiated prior to subsequent TFTP phase. If the filename is not
specified, this also forces a BOOTP/RARP phase to occur first. Note
that the defaults specified by the command always initiates a
BOOTP/RARP phase. In any case the booting (server) IP address is
displayed as well as that of any failing IP address.
Once the IP addresses are obtained from the BOOTP server (or the
configuration parameters, if specified), the IP addresses are
checked to see if the server and the client are resident on the same
network. If they are not, the gateway IP address is used as the
intermediate server to perform the TFTP phase with.
