Figure 12-5 Modbus TCP Master Connection configuration
6.
Enter the
IP Address of a slave device you want to poll data from.
7.
Set the
TCP Port. By default, Modbus TCP uses port 502.
8.
Set the
Conn Timeout value. This specifies how long (in seconds) to wait for the
TCP connection to be established. If it times out or fails for any other reason,
then it will wait the
Cycle Delay before retrying.
9.
Set the register order for multi-register, 32-bit floating point and integer values as
needed. If set to
Low First, the low order register is transmitted first. Likewise,
if set to
High First, the high order register is transmitted first.
10.
Set additional parameters:
Cmd Delay (ms) – (Command Delay) This specifies the delay between
commands. After receiving a response there will be a delay of at least this
amount before the next command is sent. This may be required for
communications paths that have a half-duplex part like RS485.
Cycle Delay (ms) – This is how long the SmartVue will wait after receiving the
response from the last command in the polling table before starting a new cycle.
Rsp Timeout (ms) – (Response Timeout) This is how long the SmartVue will
wait for the slave to respond.
Cmd Retries – (Command Retries) This is how many times to retry the last failed
command before moving on to the next command in the polling table. If you
have a high cycle delay you may want to use this feature. The command delay
will be used between retries.
11.
Press the
Polling Table button to display a list of all the commands the SmartVue
will send for the given TCP connection.
