Network

The Network component allows to configure the BACnet (IP or MS/TP) or Modbus (TCP/IP or RTU) client network. It allows to add remote devices (using the Device component) and configure basic polling schedule for such devices and their points.

The Network component has the following slots:

• Status: indicates the current status of the component. If the component works, its status is OK; the component's status becomes Disabled if its Enabled slot has been set to false.

  • Available information: Disabled, OK.

• Info: provides a detailed information about the Disabled and Fault statuses of the component;

  • Available information:

    • Could not find selected Port (status Fault): occurs, for example, when the interface set for the network gets deleted;

    • Incorrect placement - must be placed under a network protocol (status Fault): occurs, when the Network component is placed in a different location than under the BACnet/Modbus component in the Networks container;

    • Could not find Interfaces container (status Fault): occurs if the Interfaces folder gets manually removed;

    • Network disabled (status Disabled): the Enabled slot in the Network component is set to false;

    • Interface disabled (status Disabled): the Enabled slot in the interface component (IpPort/SerialPort), assigned to the network, is set to false;

• Enabled: change of the slot's value enables or disables the component;

  • Available settings: true (enabled), false (disabled);

Note: If the Enabled slot is in false (meaning the component is disabled), the Status slot becomes Disabled.

• Interface: allows to set the Ethernet interface for BACnet IP or Modbus TCP/IP client network and the Serial port for BACnet MS/TP or Modbus RTU;

• Fast Poll Frequency: sets the time between requests for the point’s value sent in the fast mode;

• Normal Poll Frequency: sets the time between requests for the point’s value sent in the normal mode;

• Slow Poll Frequency: sets the time between requests for the point’s value sent in the slow mode;

• Ping Frequency: sets the time between testing requests to check the device’s connection.

• Retry Count: shows a number of repeated requests;

• Response Timeout: time set to wait for the device's response;

• Write On Up: allows to send all network points values to points in server devices on the network when the devices go from the Down status to OK;

• Write On Enable: allows to send all network points values to points in server devices on the network when the devices go from Disabled to Enabled.

Slots applicable only for Modbus network:

• Force Coil Function: allows to specify whether to force Modbus function 15 for all coil write operations on the device or use network settings;

• Preset Register Function: allows to specify whether to force Modbus function 16 for all register write operations on the device or use network settings.
