Read 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.
Read Register Count
0 to 4000
The Read Register Count parameter defines the size of the module's input
database, up to a maximum value of 4000 words.
Write Register Start
0 to 3999
This parameter specifies the starting register in the module where the data will be
transferred from the processor to the module.
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.
Error/Status Block Pointer
1 to 7000
The Error/Status Block Pointer parameter is used to specify the range of
database registers to use for error and status data. The value range should be no
lower than 700, to avoid overwriting data, and no higher than 6970, to allow
sufficient space for the error/status block.
Backplane Fail Count
0 to 65535
This parameter specifies the number of consecutive backplane transfer failures
that can occur before communications should be halted.
