The Serial Statistic page is used to monitor the health of the controller network. These numbers will
help identify when there are issues with wiring, duplicate Modbus ID addresses or noise on
communication wires on the controller side of the network. In this example, controller number 11 is
experiencing failure in communication quality.
Timeout Errors increments anytime that a controller does not respond in an appropriate amount of
time.
Retry Errors increments anytime that a controller does not respond after 3 attempts to read
information.
CRC Errors increments anytime that the controller responds with a bad packet.
Bad Polls increments when there are timeouts and the retries did not successfully retrieve information.
Good Polls increments on each valid packet received.
Illness increments anytime that there are 5 CRC or Timeout errors in a row. After a count of 5 in the
Illness column, the controller is flagged as having no communication. On the next valid packet
received, the Illness value is cleared to zero and communications is restored.
You must refresh the browser to see these numbers update.
