You can transfer configuration block data between the CVIM module and
CFG Host using block transfer reads and writes. These blocks contain the
operating instructions for the CVIM module (refer to Appendix D). When
transferring configuration blocks, note the following:
When the CVIM module is receiving configuration blocks from a CFG Host,
the CVIM module will leave the active run mode, set the module busy bit,
turn off local I/O, turn off the data valid bit, and ignore any input triggers
(setup menu option is also disabled). After receiving one or more new
configuration blocks (and the last block bit), the CVIM module will validate
the entire configuration since many of the operating parameters are
interrelated.
If the CVIM module detects an invalid configuration, the new configuration
will be ignored and the CVIM module will set the Configuration Fault bit
and operate using the old configuration. Note that this is true for
TEMPLATE blocks. These blocks are described in the next section.
