alarm occurs. Enter the command string for the program you want to run. You can
include Alarm System variables as arguments by clicking the Varia ble s. .. button and
selecting the variables you want.
On a Windows NT or WIndows 2000 system, if you are running the EPICenter
server as a service, and you specify a program that does output to the desktop,
that program will not run unless you specify that output to the desktop is allowed
when you start the server service. You can solve this problem by restarting the
EPICenter server and specifically allowing interaction with the desktop. Refer to the
Alarm System section in Appendix A, Troubleshooting, for instructions on restarting the
EPICenter server service with this option enabled. If you are running the EPICenter
server as a regular program, this is not a problem.
If you want to specify a batch file that does output to the desktop, you must
specify the “.bat” file within a DOS “cmd” command, as follows:
cmd/cstart<file.bat>
where <file.bat> is the batch file you want to run.
• Execute script: Click the check box to have the Alarm System executea Tcl script when
this alarm occurs. Enter the script commands into the window provided.
You can write your own scripts that access selected EPICenter database variables. See
“Writing Tcl Scripts for Alarm Actions” on page 5-39 for more information.

capability, do the following:
