More Information

Functionally based on pvMail UNIX shell script written in 1999.


Watches an EPICS PV and sends email when it changes from 0 to 1. PV value can be either integer or float.


When “running”, wait for trigger PV to go from 0 to 1. When that happens, fetch mail message from message PV. Then, send that message out to each of the email addresses. The message content is prioritized for view on a small-screen device such as a pager or a PDA or smartphone.
