Hi List: Thanks to all of you for the great input. I decided to try out for now the "script-file-switching-the-block-into-AUTO-and-then-back-to-MANUAL-for-a-short-time-around-midnight" method. It seemed simplest since we already have script files running similar things so the configuration was truly minimal for me. Tim Lowell: I just used one of your scripts as a template to create my own and then edited crontab. :) Angie Gruber OxyVinyls, La Porte, TX _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com _______________________________________________________________________ This mailing list is neither sponsored nor endorsed by Invensys Process Systems (formerly The Foxboro Company).
