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 for Modbus

The Network component for BACnet

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.

• 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 client network and the Serial port for 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.

Slots applicable only for Modbus network:

• Force Coil Function Select: allows to specify whether to force Modbus function 15 for all coil write operations on the device or use network settings;
• Preset Register Function Select: allows to specify whether to force Modbus function 16 for all register write operations on the device or use network settings.
• Write On Up: allows to send all network points values to Modbus 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 Modbus points in server devices on the network when the devices go from Disabled to Enabled.
