      Description

      When the I/O data is fragmented and slave has delay in poll response, the master poll request cause disruption in receiving of fragmented response from slave.

       

      Tested against slave with delay response. 1ms production inhibit time. As seen in the trace. The master seem to ignore the response from slave and reestablish the connection after only 2 poll request. (The master should send 4 poll request with time gap of EPR before try to reconnect again)
