Configuring Communication Module Connection Settings

Overview

Control Expert automatically creates a connection between the communication module and a remote device when the remote device is added to the Control Expert project. Properties defining each connection must be configured in the DTMs for both the connection module and the remote device.

Use the Connection Settings page to view and edit connection properties from the perspective of the communication module.

To open this page, in the left pane of the Device Editor expand the navigation tree and, under the Device List node, select <remote device> → <connection>, where:

<remote device> represents the name of the selected remote device appearing in the Device List, and
<connection> represents the name of the selected connection, which depends upon the types of connections supported by the remote device and the particular connection type selected in the connection configuration settings for the remote device DTM.

NOTE: The name of the connection displayed in the Device List depends upon the types of connections supported by the remote device and the particular connection type selected in the connection configuration settings for the remote device DTM.

Refer to the topic Configuring Properties in the Device Editor for instructions on how to edit properties

Communication Module Connection Properties

The following connection settings for this sample configuration can be viewed or configured in the DTM for the communication module:

Setting	Description
Connection Bit	(Read-only) The system generated number, from 0 to 256, for the health bit for this connection. NOTE: The first numbered Connection Bit is 0, which maps to: HEALTH_BITS_IN[0].0: the first bit in the first byte of the zero-based HEALTH_BITS_IN byte array, and CONTROL_BITS_OUT[0].0: the first bit in the first byte of the zero-based CONTROL_BITS_OUT byte array,
Request Packet Interval (RPI)	The refresh period, from 2 to 65535 ms, for this connection. Default = 12 ms NOTE: This parameter can be set in the DTM for the communication module, or in the DTM for the remote device.
Time-out Multiplier	This setting, multiplied against the RPI, produces a value that triggers an inactivity timeout. Setting selections include: x4, x8, x16, x32, x64, x128, x256 and x512. Default = x4 NOTE: To view the Time-out Multiplier parameter, Control Expert must be operating in Advanced Mode.
