Connectivity Monitoring and the RTV

Overview

DataXchange can monitor the connection health of three different types of communication. The first is Equipment Connectivity Health which refers to tracking the time in which the DataXchange Service has a connection to the Equipment Source such as Focas, MTConnect, or the SRC. The second is Command Connectivity Health which monitors the health of the DataXchange command for the associated equipment. The third is the Cloud Connectivity Health which refers to tracking the time in which the DX Service is communicating with the cloud.

Connection Monitoring can be viewed through the RTV Equipment Status Grid. This can be done when building an RTV screen. When Assigning a view select the Equipment Status Grid, then configure the columns then make sure the associated column is selected. Additional information on the Equipment Status Grid can be found here.

Connectivity RTV display

The three different connectivity aspects and their health can be viewed at any given time within the RTV. Adding this data to the RTV is simple and done through the RTV Equipment Status Grid View.

When the Connectivity Column is added to the Equipment Status Grid View it will display the current health of that equipment indicated by a corresponding color. The most recent record will determine the color to be used.

Monitored	Notes	Color	[PCSDB.connectivity_status] value
Equipment	This indicates that all three aspects are in good condition. The command is enabled, the connection from the DX Service to the equipment is good and the connection from the DX Service to the Cloud is also good. In order to monitor this level of status the connectivity expressions must be assigned to the equipment.		1
Equipment	This indicates that there is an issue with the connection from the DX Service to the equipment. This may be a network connectivity issue or the power may be off at the equipment control. In order to monitor this status level, the connectivity expressions must be assigned to the equipment.		0
Command	This indicates the command is enabled and the DX Service has access to the DataXchange servers. This color should only be visible when the expressions are NOT assigned.		3
Command	This indicates that the Command that enables the communication to the equipment is currently not enabled.		2
Cloud	The DX Service is running and able to communicate with the Cloud. The Equipment has not yet been configured, or has a configuration problem, therefore the other connectivity monitoring items are unavailable, and DataXchange can only monitor the connection of the DX Service to the DataXchange Servers.		5
Cloud	The DX Service is unable to communicate with the Cloud. The DX Service may not be running or there may be an Internet connection issue from the server where the DX Service is running. Since the DX Service cannot communicate to the Cloud, the state of the connectivity to the equipment and the state of the command cannot be reported, and therefore DataXchange can only report that there is an issue with the connection between the DX service and the DX servers.		4
	There is no connectivity data in the database for the selected equipment. This state should only be visible during an initial account setup.

• Equipment Connectivity Health – This monitors the connection to the equipment source when the appropriate expressions are assigned.
• Command Connectivity Health – This monitors whether or not the command is enabled or disabled.
• Cloud Connectivity Health – This monitors whether or not the DX Service is connected to the Cloud.

*When a command (gear associated to equipment) in the Equipment Tree on the DataXchange tab is red or red with an X this is an indicator that it is not running. If correct Communications and Expressions are assigned to the equipment simply selecting the Start button will activate the command, starting the collection process. Additional information on Expressions and Communications can be found here.
