File M0 Offset File Register Content Description
N10:49 50 N32:58 5058 Retry Count This parameter specifies the
number of times a command will
be retried if it fails. Valid value in
the range of 0 to 10.
N10:50 51 N32:59 5059 Error Delay
Count This parameter specifies the
number of polls to be skipped on
the slave before trying to re-
establish communications. After
the slave fails to respond, the
master will skip commands to be
sent to the slave the number of
times entered in this parameter.
Valid value in the range of 0 to
65535.
N10:51 52 N32:60 5060 Slave List
Pointer This parameter specifies the
starting address in the virtual
database where the 256 slave
status values will be written. If the
parameter is set to -1, the slave
data will not be placed in the
database. Valid value in the
range of -1 to 4743.

N10:53 54 N32:62 5062 First File This parameter is used when a
request for a file is received on
the communication port. This field
is required when responding to
PLC5 and SLC DF1 commands.
Use this parameter to define the
virtual file(s) to be simulated on
the module. This value is fixed at
7 for N7.
N10:54 55 N32:63 5063 File Size This parameter specifies the size
of each file to be simulated on the
module. All files simulated are
defined to have the same
assigned size. This value is fixed
at 200.
N10:55 56 N32:64 5064 File Offset This parameter sets the database
register location of the first
element in the first file simulated
in the module. All offsets in the
first file and subsequent files will
be computed using the address
specified. This value is fixed at 0.
Therefore, the module assumes
N7:0 starts at the database offset
of 0 and each file is 200 words in
size.
