Notification Process
Use
The notification process enables you to monitor production facilities and record any sudden, undesired events and report them to a destination system. However, you can also use this process to record regularly occurring, desired events such as confirmations.
With this process, you can monitor tags from the source system (from a control system for a production plant, for example) for possible changes. You can specify the trigger conditions in detail that must be satisfied for PCo to send a notification message to one or more destination systems.
You can specify the following as trigger conditions:
-
Changes in values
-
Formulas
-
Events (such as production standstill)
You can use the following source systems for the notification process:
-
All OPC source systems
-
MQTT source system
-
PI source system
-
Proficy Historian source system
-
Socket source system
-
Asset Framework source system
-
File monitor source system
-
File system source system
-
Modbus source system
-
ODBC source system
-
OLE DB source system
Process
-
The PCo system continually receives measurement values from the source system and checks whether the condition that you defined in the Trigger screen area is met.
For an OPC DA source system, the source system checks whether the condition is met and only sends a tag to PCo if the trigger condition is met.
-
If the trigger condition is met, PCo creates a notification message and sends it to one or more destination systems.
-
If the destination system is an SAP MII system, for example, SAP MII processes the notification message.
Example
You are monitoring a boiler with PCo. The boiler control system (source system) is an OPC DA system. You have specified that the boiler temperature tag is to be sent to PCo if the measured value falls short of or exceeds the permissible temperature bandwidth.
You have selected the trigger type OnTrue in the Trigger screen area.
You have specified the formula TAG_TEMP<57 || TAG_TEMP>63 as the trigger condition.
If the measured value lies below 57°C (134.6°F) or above 63°C (145.4°F), PCo creates a notification message and sends it to the destination system (an SAP MII system, for example). The SAP MII system can then send an e-mail to a previously defined recipient or create a maintenance notification in ERP, for example.
