This screen allows you to modify which ports are used by the Ewon gateway for some key protocols and to set some parameters that will apply to all the Ewon IO servers.

The Ewon Servers and Gateway IP Ports section allows you to adjust the TCP ports used by your Ewon device for several different PLC communication protocols.

These ports are used both to poll data using these protocols and when the Ewon device is acting as a serial to Ethernet gateway.

To disable ports used for transparent gateway, set the corresponding port to 0.

Reboot your Ewon device to apply any changes.

The Disable Tags in Error option can be very useful when troubleshooting tag setup issues.

For communication optimization purposes, the Ewon device groups tag requests and responses.

As a result, when the Disable Tags in Error option is not selected, a single tag in error can cause other tags to incorrectly appear in error as well.

However, when this option is selected, the tag in error will be removed from the group and no longer polled. A message stating that polling has been disabled for this tag will be written in the event log.

Invalid tags will be polled again when the IO Server or tag setup are modified or when a manual “Init” operation is performed from the IO Server setup screen.

Remember to uncheck the Disable Tags in Error option once you have completed your commissioning or maintenance task.

Use the Default TCP RX/TX Timeout field to adjust the IOServer TCP timeout. Reboot your Ewon device to apply any changes.
