State Value
Definition
-3
Server closed connection for client or server is not available.
-2
Unable to open connection with specified server.
-1
Unable to open connection with specified server because of invalid IP address.
0
The client is idle and not connected.
1
The client set to connect to the server and waiting for the connection to
establish.
2
The client is connected to the server and can transfer data.
3
The connection is being closed for the client.
A value less than one indicates that the client is not connected to a server and is available
for use. If the client was previously used and an error condition existed relative to the
socket, this parameter will be set to a value less than zero. If the client socket closed
normally, the value will be set to 0.
When the ladder logic requests a new connection, it will set the parameter to a value of 1.
The module will recognize this request and initiate the connection with the specified server.
If the connection is established, the parameter will be set to two. Data may now be
exchanged between the client and the server.
