3.2.3 MBTCP Client x
This section defines the general configuration for MBTCP Client x. You can
configure up to 20 MBTCP clients, each using the parameters below. In the
ProSoft Configuration Builder tree view, double-click the MBTCP
C LIENT X icon.
Parameter Value Description
Enabled Yes or No Enables this client
Start Active Yes or No Specifies whether to start with commands active on boot up
Error/Status Pointer -1 to 9990 Specifies the starting register location in the module’s database for
the error/status table for this client. If you enter a value of -1, the
error/status data is not placed in the database.
All other valid values determine the starting location of the data. This
data should be placed within the read data range of module memory.
Command Error Pointer -1 to 9999 Specifies the address in the module’s database where the command
error data is placed. If you set the value to -1, the data is not
transferred to the database. This data should be placed within the
read data range of module memory.
Minimum Command
Delay 0 to 65535
milliseconds Specifies the number of milliseconds to wait between receiving the
end of a server's response to the most recently transmitted command
and the issuance of the next command.
You can use this parameter to place a delay after each command to
avoid sending commands on the network faster than the servers can
be ready to receive them. It does not affect retries of a command, as
retries are issued when a command failure is recognized.
Response Timeout 1 to 65535
milliseconds Specifies the command response timeout period in 1 millisecond
increments. The client waits for a response from the addressed
server within the timeout period before re-transmitting the command
(Retries) or skipping to the next command in the Command List.
The value depends on the communication network used and the
expected response time (plus or minus) of the slowest device on the
network.
Retry Count 0 to 10 Specifies the number of times a command is retried if it fails.
Float Flag Yes or No Specifies if the Daniel/ENRON-specific floating-point data access
functionality is to be implemented. If you set the Float Flag to Y,
Modbus functions 3, 6 and 16 interpret floating point values for
registers as specified by the two following parameters (Float Start,
Float Offset).
Note: You do not need to enable this parameter for most
applications using floating-point data.
Float Start 0 to 65535 Specifies the first register of floating-point data. All requests with
register values greater-than or equal to this value are considered
floating-point data requests. This parameter is only used if the Float
Flag is enabled.
