6.7.2 Example: Oil & Gas Application
 There is not much data that typically needs to be moved from each IED to the
PLC in this type of application.
 In this example, the user may want to send commands from a process DCS
system to control breakers.
 The PLC needs to transfer five to ten Data Attributes through the ProSoft
gateway to each of many IEDs.
6.7.3 Monitoring
In a typical monitoring application, several types of actions may be needed:
 Automatic action required: Monitoring the currents and voltages and the
system taking an immediate automatic action, like tripping a circuit breaker.
 Operator action required: Monitoring of the current temperature of gas in a
gas insulator around a circuit breaker. This could result in actions initiated by
an operator, such as sending maintenance people on-site.
 Post mortem analysis: Monitoring and collecting information about equipment
condition, to be analyzed by a specific tool, resulting in recommendations for
maintenance.
