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.

software

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

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.
