Should there be a single tag that encompasses faults on either the PLC UPS (upstairs in counting house) or the I/O UPS (down in hall)?<br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div>2.) Is the wiring to the I/O UPS units in the hall to the appropriate PLC channels complete?<br></div><div><br data-mce-bogus="1"></div><div>3.) Since there are no SHMS I/O channels upstairs in the counting house, should the PLC UPS status be read by the HMS PLC and passed to the SHMS PLC as an ethernet tag? If this is <strong>not</strong> the case, has the cabling between the PLC UPS upstairs and the SHMS I/O channel downstairs been ran?<br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div>4.) A 24 V power supply is needed to generate the signal that indicates a UPS fault for the PLC UPS. Is there one available to install in the rack next to the UPS and dsub-to-terminal-block adapter on the second floor of the counting house?<br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div>Best regards,<br data-mce-bogus="1"></div><div>Tyler<br data-mce-bogus="1"></div><div><br></div><div><br></div><hr id="zwchr" data-marker="__DIVIDER__"><div data-marker="__HEADERS__"><b>From: </b>"Steve Lassiter" <lassiter@jlab.org><br><b>To: </b>"dsg-hallc controls" <dsg-hallc_controls@jlab.org><br><b>Sent: </b>Monday, July 30, 2018 2:02:37 PM<br><b>Subject: </b>[Dsg-hallc_controls] UPS status<br></div><div><br></div><div data-marker="__QUOTED_TEXT__"><style>p { margin: 0; }</style><div style="font-family: arial,helvetica,sans-serif; font-size: 10pt; color: #000000">Hi,<br><br> There are three UPS being used for the HallC control systems that need to watched and acted upon.<br><br>HMI I/O UPS<br>SHMS I/O UPS<br>HMS and SHMS PLC UPS<br><br>For the HMS. The status of the I/O UPS was originally planned to be read by the rotation rack I/O chassis, module 3 channel 13.
