Module Configuration with RSLogix

2.4.1 [Backplane Configuration]

This section contains the backplane configuration information. It is used to
determine the number of registers moved between the module and the PLC
processor. Additionally, the backplane failure condition is defined as to whether
to continue using the protocol.
Module Name
0 to 80 characters
This parameter assigns a name to the module that can be viewed using the
configuration/debug port. Use this parameter to identify the module and the
configuration file.
Read Register Start
Range 0 to 3999
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 3999.
Read Register Count
Range 0 to 4000
This parameter specifies the number of registers to transfer from the processor to
the module. Valid entry for this parameter is 0 to 4000.
Write Register Start
Range 0 to 3999
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 3999.
Write Register Count
Range 0 to 4000
This parameter specifies the number of registers to be transferred from the
module to the processor. Valid entry for this parameter is 0 to 4000.
Failure Flag Count
0 through 65535
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 0,
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.
