Write Register Start
0 to 4999
This parameter specifies the start of the Write Data area in module memory.
Data in this area will be transferred in from the processor.
Note: Total user database memory space is limited to the first 5000 registers of
module memory, addresses 0 through 4999. Therefore, the practical limit for this
parameter is 4999 minus the value entered for Write Register Count, so that the
Write Data Area does not try to extend above address 4999. Read Data and
Write Data Areas must be configured to occupy separate address ranges in
module memory and should not be allowed to overlap.
Write Register Count
0 to 5000
This parameter specifies the size of the Write Data area of module memory and
the number of registers to transfer from the processor to this memory area, up to
a maximum value of 5000 words.
Note: Total Read Register Count and Write Register Count cannot exceed 5000
total registers. Read Data and Write Data Areas must be configured to occupy
separate address ranges in module memory and should not be allowed to
overlap.
Failure Flag Count
If this value is greater than zero the protocol communication will be interrupted
once a backplane failure is detected, or communication with the processor fails.
A value of zero will disable this feature.
Initialize Output Data
0 = No, 1 = Yes
This parameter is used to determine if the output data for the module should be
initialized with values from the processor. If the value is set to 0, the output data
will be initialized to 0. If the value is set to 1, the data will be initialized with data
from the processor. Use of this option requires associated ladder logic to pass
the data from the processor to the module.
