Server Script usage

Using Experion Server Scripts

• Introduction– The Experion system allows one to initiate a Server

Script based on an event. These events could be from an alarm or a change in state of an input. Another very useful initiator can be when a SCM step becomes active.

Log only Server Scripts

• Scripts can be forced to go to the Journal Log so that an Operator does not get distracted by them coming on the Message Summary display. These messages can then be scheduled to be printed out or sent to a virtual printer based on how you setup up your report.

Log only Server Scripts example

• The example below is a script that is used for a report in a waste treatment operation. There are many instances throughout the days of activities that need to be reported. The messages all start with “wtr”; this allows one to setup up a custom report that only prints out messages with a certain wildcard, in this case “wtr”.

– If StrComp(EventInfo.value, "ON", vbTextCompare) = 0 Then

– Dim AlmDtls

– Set AlmDtls=Server.CreateAlarmDetails

– ' AlmDtls.Name="WasteTreatmentMsg"

– AlmDtls.Priority=hscJournal

– AlmDtls.Type="MESSAGE"

– AlmDtls.Area="Waste Trt"

– AlmDtls.Description="wtr:RE-811 FEED Phase Started"

– Server.GenerateAlarm AlmDtls

– Set AlmDtls=nothing

– End If

Message Summary Server Scripts

• Sometimes it is essential that the Operator be made aware of an event, in this case it is beneficial to alert the Operator and sent the message to the Message Summary page. – Obviously you want to make sure that your Flex and

Consol station are properly configured to provide an audible alarm for the message summary, otherwise important information may not be retrieved in a timely manner.

Message Summary Server Scripts

– Below is an example of a script that informs the Operator of how much of an ingredient was charged into a reactor. This script is initiated by a SCM, and it is a so called Common or Shared SCM, there are multiple reactors that use this SCM ,thus the unit specific identifiers; the “auxunit” parameter.

Conclusion

• Server Scripts are a powerful way of storing and conveying information to the Operator.

• A question often asked is why not just use the build-in message block. The limitation with the message block is that it does not allow one to use dynamic data; a message block can only display the text field that was programmed into it. It would be a great enhancement if the message block had a feature that incorporates dynamic data, but till then, the Server Script will fill your needs.
