Register Content Description
5023 ENQ Delay This parameter specifies the number of milliseconds
to wait after a DLE-ACK is received from a slave
using half-duplex mode before the DLE-ENQ request
is made for data. Enter a value in the range of 0 to
65535.
5024 Command Count This parameter specifies the number of commands to
be processed for the port. Enter a value of 0 to 100.
5025 Minimum Command
Delay This parameter specifies the number of milliseconds
to wait between the initial issuance of a command.
This parameter can be used to delay all commands
sent to slaves to avoid "flooding" commands on the
network. This parameter does not affect retries of a
command as they will be issued when failure is
recognized. Enter a value in the range of 0 to 65535.
5026 Command Error Pointer This parameter sets the address in the internal DF1
database where the command error data will be
placed. If the value is set to -1, the data will not be
transferred to the database. Enter a value of 0 to
4999.
5027 Response Timeout This parameter represents the message response
timeout period in 1-ms increments. This is the time
that a port configured as a master will wait before re-
transmitting a command if no response is received
from the addressed slave. The value is set depending
upon the communication network used and the
expected response time of the slowest device on the
network.
5028 Retry Count This parameter specifies the number of times a
command will be retried if it fails. Enter a value in the
range of 0 to 10.
5029 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. Enter a
value in the range of 0 to 65535.
5030 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. Enter a value
in the range of -1 to 4743.
5031 Slave List Frequency Not used in this version of the software
5032 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.
5033 File Size This parameter is used to specify 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.
