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.

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.
