transmitted and received via <TX$> (transmit) and <RX$> (receive) for as long as
<Connect-F> remains high.
The <status> output is used for diagnostics and reports the connection status. The
valid values are shown in the following table:
Analog Value Connection Status
0 Not connected
1 Waiting for connection
2 Connected
3 Connection failed
4 Connection broken remotely
5 Connection broken locally
6 Performing DNS lookup
7 DNS lookup failed
The TCP/IP Client symbol differs from the TCP/IP Server symbol (refer to graphic
below) in that the Server symbol can only listen for a connection from a device,
whereas the Client symbol can initiate the connection.
Detail View of the TCP/IP Server Symbol in SIMPL Windows’ Programming Manager
The TCP/IP Server symbol enables TCP/IP communication between any device with
a TCP/IP port and the control system. It differs from the TCP/IP Client symbol in
that the latter symbol can initiate a connection with a device, whereas the TCP/IP
Server symbol can only listen for a connection.
The symbol must be assigned the IP address of the device, while the port address of
the device must be entered in the <Port> parameter of the symbol. Both the IP
address and port should be provided by the manufacturer's documentation.
When the device establishes communication with the symbol, the <Connect-F>
output goes high. Serial data can then be transferred via <TX$> (transmit) and
<RX$> (receive) for as long as <Connect-F> remains high.
The <status> output is used for diagnostics and reports the connection status. The
valid values are the same as those shown in the previous table.
The optional <enable> input has a default value of 1. If <enable> is defined and
goes low, no connection can be established (and <status> will equal 0).
