9.0 Ethernet Data Communications
The SmartVue is configured as a TCP/IP server and can send process, control process,
I/O data, and Modbus commands and responses out through the Ethernet port. Up to five
concurrent TCP/IP connections can be made with the SmartVue.
The screen image data can also be sent and displayed or controlled using the
SmartVue
Remote application described in Section 20.0.
The SmartVue can accept ASCII formatted commands to request specific sets of data or
cause it to stream on a continuous basis.
9.1
Ethernet Settings
To properly connect to the SmartVue over TCP/IP appropriate configuration settings are
needed. The Ethernet settings consist of the following:
The
IP address is a unique number that identifies a SmartVue or any other TCP/IP device
on a network, so when requests for information are sent to it, it knows to respond. No
other TCP/IP devices on the network should have this address.
The
subnet mask, together with the IP address defines the network that the SmartVue
belongs to and which IP addresses can be reached within it.
Each IP address is divided into two parts: the shared network part and the unique host
part. When sending data to a device with a different network part, it must be sent through
a router to reach its destination (i.e., to a different network). If they are the same, no
router is needed. The host part sets how many unique IP address are allowed on the
network. So, with a subnet mask of 255.255.255.0 the first three parts of the IP address
will form the fixed network number, while the last part of the IP address will allow for
256 (0 to 255) different possibilities.
The
gateway IP address is the address of the device (such as a router) that serves as the
interface between one network and another.
The port number distinguishes command requests from any other type of request that the
SmartVue may receive. Responses will thus only be generated and returned if a
command is sent to the SmartVue using this assigned port number. Port numbers should
be in the
registered port range of 1024 to 49151.
To configure the SmartVue’s Ethernet settings
1.
Select
MENU > Communications > Ethernet Settings. The Ethernet Settings
screen shown below will be displayed.
2.
Enable the Ethernet port using the
Enabled/Disabled control at the top of the
screen. If the unit is connected to a network, the yellow LED on the connector
will turn on and the green LED will flash in proportion to the amount of network
traffic. When the control is set to “Disabled” the Ethernet port is disabled.
