User Communication Client
When a client connection is configured as the user communication client, the SmartAXIS communicates with the specified server
device according to the settings configured in the ETXD and ERXD instructions that are programmed for the client connection. The
remote host number and other communication settings can be configured in the Connection Settings tab in the Function Area
Settings dialog box.
Specifications (User Communication Client)
Note 1: Can be enabled or disabled in Function Area Settings, Connection Settings.
Note 2: The settings can be configured in the Connection Settings tab in the Function Area Settings dialog box.
Note 3: The receive timeout is enabled when using the ERXD instruction. To disable the receive timeout, set it to 25500 ms.
Establishing/Disconnecting User Communication Client Connections
When user communication clients are configured, connections are established on TCP/IP protocol. The connections are established
when ETXD/ERXD instructions are executed or when the SmartAXIS has started to run (See Note 1 above). After a connection has
been established, the connection will be kept open until either the SmartAXIS is stopped or a special internal relay allocated to the
connection is turned on.

The allocation of the user communication receive instruction cancel flags for each client connection is shown in the table below.
For details about the user communication receive instruction cancel flag, see Chapter 25 "User Communication Instructions" in the
