OPC DA
The Web-IO is already preset for OPC operation by default. If you want to use OPC,
you only have to activate OPC access under
Communication paths » OPC UA
and
enable the switching of the outputs if required.
For your OPC client to communicate with the Web-IO the W&T OPC server must be
installed. Access via third-party OPC servers is not provided.
Select the menu item
Devices » New I/O Device
in the OPC
Server. Enter the IP
address and password of your Web-IO and select the device type. Confirm with
OK
.
Finally, you must accept the new entries as active configuration via the menu item
File » Save
.
