6.5 MVI56E-MCM Configuration Data
This section contains listings of the MVI56E-MCM module's database related to
the module's configuration. This data is available to any node on the network and
is read from the ControlLogix processor when the module first initializes.
6.5.1 Backplane Setup
This parameter specifies the starting register in the
module where the data transferred from the
processor will be placed. Valid range for this
parameter is 0 to 9999.
This parameter specifies the number of registers to
transfer from the processor to the module. Valid
entry for this parameter is 0 to 10000.
This parameter specifies the starting register in the
module where data will be transferred from the
module to the processor. Valid range for this
parameter is 0 to 9999.
This parameter specifies the number of registers to
be transferred from the module to the processor.
Valid entry for this parameter is 0 to 10000.
This parameter specifies the number of successive
transfer errors that must occur before the
communication ports are shut down. If the
parameter is set to zero, the communication ports
will continue to operate under all conditions. If the
value is set larger than 0 (1 to 65535),
communications will cease if the specified number
of failures occur.
This parameter specifies the register location in the
module's database where module status data will
be stored. If a value less than zero is entered, the
data will not be stored in the database. If the value
specified in the range of 0 to 9940, the data will be
placed in the user data area.
