5.4 MVI46-DFCM Command Control
Command Control data is received from other nodes on the network that can
control the MVI46-DFCM module. Specific values are written to regions of this
block to control the module. Currently, the module is programmed to handle the
receipt of the following requests: write configuration to processor, warm boot and
cold boot.
The remote node controls the module by writing one of the following values to
register 7800 (address N46:0):
9997 Write configuration in database to the processor and warm boot the module
9998 Warm boot the module
9999 Cold boot the module
The control register is cleared (a value of 0) after the operation is executed with
the exception of the 9997 command. If the module fails to successfully transfer
the configuration to the processor, an error code will be returned in the control
register as follows:
0 No error, transfer successful
-1 Error transferring general configuration information
Ladder logic must handle the 9997 command. No ladder logic is required when
using the warm or cold boot commands.
