- Software
- Magnet Monitor 3 Revision 1.56. Magnet Monitor 3 revision 1.56, distributed to sites with Connectivity automatically post FMI 60755 release on 6/23/2008. See Long Description for Fixes and Notes. Magnet Monitor 3 Revision 1.56 Software (formerly known as 1.55). Fixes New magnet type selection page with menus for both compressors. New remote commands to change the compressor selections. New uploaded properties to show the current compressor selections. A fix to the satellite interface so MM3 doesn't lose the sat link if it gets a malformed entitlement message. Changed configuration files so ABM and BOM magnets with DT500 sensors use the correct lookup tables. Disabled alarms actually won't generate alarms. The net mask no longer has to be entered with extra zeros (i.e. - 255.0.0.0 is now good enough instead of 255.000.000.000). The "Show Digital IO" web page shows all compressor types correctly - no more messages saying that Leybolds are inverted. New alarm limits for ABM and BOM for 2nd_stage_shield (is now 10K to 25K, was previously 3.5K to 10K). Changed Master Interval to 720 minutes for LCC and Non-Zero boil off magnets and 360 minutes for HFOs to reduce dispatch volume. NOTES •Software will be downloaded to all communicating sites except satellite modems. •Currently there is no CD that is orderable as a FRU for sites that do not have communication or have a satellite modem so that the software can be manually updated.
