Can I send data from one device to two Kepservers?

For what reason do you need the data to go to two kepservers?

Not sure how they are communicating, usually Kepware reaches out to a device and pulls information from the device.

What protocol is being used?

It is possible that your device only allows one connection at one time.

If you need the value bound several times in the same ThingWorx, you can use a remote binding and then local bindings to subsequent properties.

If you need the value to go to two ThingWorx instances, you can consider using the OPC Aggregator.

The attempt to add item error is unrelated and means a client application is making a request for an address that doesn't exist in either the KEPServerEX configuration or the device. Here is a link to the Kepware knowledgebase article that covers this error:

Article - CS272971 - Error Attempt to add item '<Channel.Device.Tag>' Failed in PTC Kepware Products

Multiple instances of KEPServerEX can typically communicate to a single device as long as that device can handle multiple connections. You would need to check the device documentation or consult the device manufacturer to see if your specific device can handle multiple connections.
