User Communication Server
When a server connection is configured as the user communication server, a client device can access and communicate with the
SmartAXIS. The SmartAXIS communicates with the client device according to the settings configured in the ETXD and ERXD
instructions that are programmed for the server connection. The local host number and other communication settings can be
configured in the Connection Settings tab in the Function Area Settings dialog box.
Specifications (User Communication Server)
Note 1: A maximum of three connections can be allocated to user communication servers, and a maximum of three client devices can
simultaneously connect to and communicate with the SmartAXIS.
