N10:21 22 N32:25 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.
Valid value in the range of 0 to
65535.
N10:22 23 N32:26 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. Valid
value of 0 to 4999.
N10:23 24 N32:27 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.
N10:24 25 N32:28 5028 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.
N10:25 26 N32:29 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.
Valid value in the range of 0 to
65535.
N10:26 27 N32:30 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. Valid value in the
range of -1 to 4743.
