Connection Time Monitoring

Overview

DataXchange can monitor the current connection time and return the value to the RTV. Information on expressions using these variables can be found here.

Connection Time Monitoring

There is a ‘connect time’ variable for each source polled by DataXchange. Here is a list of all of the connect time variables.

Focas.connect_time	The connect time for the current Focas poll
Focas.prev_connect_time	The previous connect time
Focas.connected_time	Returns the amount of time in seconds since a successful connection to the source
Focas.prev_connected_time	The previous connected time
MTC.connect_time	The connect time for the current MTConnect poll
MTC.prev_connect_time	The previous connect time
MTC.connected_time	Returns the amount of time in seconds since a successful connection to the source
MTC.prev_connected_time	The previous connected time
SRC.connect_time	The connect time for the current SRC poll
SRC.prev_connect_time	The previous connect time
SRC.connected_time	Returns the amount of time in seconds since a successful connection to the source
SRC.prev_connected_time	The previous connected time

There are also variables related to database Connectivity Status.

PCSDB Connectivity	Returns the state of the connection (True or False)
PCSDB Connectivity_status	Returns the most recent connectivity status as a numerical value 0-5.

All of these variables are licensed at the Bronze level.

The list of numerical values and which connection states they map to can be found here.

Upon a successful connection to associated Source the current time is written to the connect time variable.
