qc_phase on control charts

jace — Fri, 09 Jun 2023 19:52:50 GMT

Hey All,

I am working with control charts and am having difficulty getting the qc_phase command to work.

Here is the alarm part of my script:

		Alarm Script(
		Write(
			"Out of Control for Nelson Rule ",
			qc_test,
			" in column ",
			qc_col,
			" during week ",
			qc_sample,
			" on tool ",
			qc_phase
		)
	)

However, when I run the script I get the following error message:

Any ideas on how to fix this? The qc_test, qc_col, and qc_sample all work.

Thank you!

Which version of JMP are you using?

JMP 15.2 Help: Control Charts

JMP 16.0 Help: Control Charts

if you are using older than JMP16.0 it could be that qc_phase is a new variable added in JMP16.0.

I am using JMP 15 so that makes sense. Do you know if there are any workarounds for this on JMP 15?

The qc_phase variable was not added until JMP Version 16.0. You can write any JSL that you desire as part of an alarm script. So theoretically you can define your own variable for this.
