Display Modbus port statistics

  1. Right-click the SIS controller for which you want to see Modbus port statistics.
  2. Click Display Modbus Statistics to open the Modbus Statistics dialog.
    This dialog shows counter values for all of the Modbus port statistics for the selected SIS controller since the last time it was reset.
  3. To restart the counter values from zero, click the Reset button.
    If power to the SIS controller is interrupted, all counter values on the Modbus Statistics dialog restart from zero after power is restored and the SIS controller comes out of the reset state.
    In the event of a switchover to the standby SIS controller of a redundant pair, all counter values on the Modbus Statistics dialog restart from zero.
