All knowing group, We have both 8.3 XP P92s and WP51Ds 6.5.1 in our control room. The P92s and Mesh have recently been added. All workstations have an annunciator keyboard. All workstations are in the same common alarm group (commgrp.cfg). Our intention was that when the operator pressed the silence button on any annunciator, all horns would silence (as it did before the P92s). As it turns out, the ability to silence horns can not done across the ATS. Has anyone found a solution? _______________________________________________________________________ This mailing list is neither sponsored nor endorsed by Invensys Process Systems (formerly The Foxboro Company).
