    In order to connect to the ESENET via TCP/IP, your PC must be on same IP subnet as the gateway. In most situations this means that the first three numbers of the IP address have to be identical. Monitoring and diagnostic The ESENET offers several web pages which allow monitoring of the status of the different communication networks and the device performance.

  • Page 29: Modbus Connection Status

    CAN’s built in fault confinement mechanism has set the node to bus-off state due to excessive errors on the CAN bus. This alarm indicates a wiring error. The ESENET will not transmit or receive any message on the CAN bus once entered this state. The device needs to be manually restarted on order to recover from this fault.

  • Page 30: Can Communication Status

    Rx time-outs A counter that increments if the master connection has timed out. Subsequently the connection is terminated by the ESENET. A time-out occurs if no Modbus request is received from a connected client within a 10 second period. Tx time-outs Number time-outs occurred when attempting to send a reply message.

  • Page 51: Modbus Data Reference

    This chapter describes how process data and configuration data of the Woodward controls are organized in logical blocks and accessed via Modbus. The ESENET supports two principal Modbus data tables one for visualisation and one for configuration & remote control. These data tables are organised in a similar manner to the serial Modbus adress ranges of the Woodward controls.

  • Page 52: Visualisation Data Table

    Registers in this data table can only be accessed if the CAN communication between ESENET and the Woodward control has been established. If this is not the case, Modbus exception code 0B Gateway target device failed to respond is returned, indicating the Woodward control is not present on the CAN bus.
