Unable to write to address <address> on device <device>. Unable to receive response from device <device> within timeout. Either the request or response could not be completed or the response is invalid.
Unable to write to address <address> on device <device>. Unable to receive response from device <device> within timeout. Either the request or response could not be completed or the response is invalid.
Error Type:
Warning
Possible Cause:
1. The Response Timeout is too short to allow the write to complete in time. The DNP server may have returned a large number of points in the feedback poll, but the timeout elapsed before the data was received.
2. There is an issue with the authentication settings.
Solution:
1. If the DNP server is returning a large number of points in the feedback poll, change the channel's Response Timeout to a value that allows the response to complete successfully.
2. Confirm that the authentication settings in the DNP client match those in the DNP server.
Notes:
1. The channel's Response Timeout should be as accurate as possible, because it is also the time that the driver waits before reporting that the device is not responding.
2. The device's Request Timeout should be greater than the channel's Response Timeout.
