6.2.2 MBTCP Client[x]
The
MBTCP Client [x]
section of the configuration specifies the parameters for
the client to be emulated on the gateway. The command list for the client is
entered in a separate section.
Parameter
Value
Description
Minimum
Command
Delay
0 to 32767
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.
Response
Timeout
0 to 65535
milliseconds
This parameter specifies the time in milliseconds that a Client
will wait before re-transmitting a command if no response is
received from the addressed server. The value to use depends
on the type of communication network used, and the expected
response time of the slowest device on the network.
Retry Count
0 to 10
This parameter specifies the number of times a command will
be retried if it fails.
Float Flag
YES or NO
This flag specifies if the floating-point data access functionality
is to be implemented. If the float flag is set to
YES
, Modbus
functions 3, 6, and 16 will interpret floating-point values for
registers as specified by the two following parameters.
Float Start
0 to 32767
This parameter specifies the first register of floating-point data.
All requests with register values greater-than or equal to this
value will be considered floating-point data requests. This
parameter is only used if the Float Flag is enabled. For
example, if a value of 7000 is entered, all requests for registers
7000 and above will be considered as floating-point data.
Float Offset
0 TO 3998
This parameter specifies the starting register for floating-point
data in the internal gateway database. This parameter is used
