Group Number 1 Group Name Destinations S Report Type HISTORY Destination Number Destination Name Figure 4 Report Access Group Definition Example IMPORTANT For the dial up VAA version the Metasys OWS containing the PC file defined to store the remote DX 9100 trend data must be online at all times If the OWS is offline at the time the trend upload occurs the samples from the DX 9100 cannot transfer to the PC s hard drive and will be lost Therefore as a precaution for dialup VAA installations define a redundant PC file destination on a different OWS on the Metasys network This second destination will save the same data as the primary PC file but will be needed only if the upload to the primary PC file fails 10 App Notes Operator Devices Troubleshooting Table 2 VAA Operation Troubleshooting Problem Workstation does not allow adjustment of setpoints or differentials of the Vibration CS object For a dial up VAA no trend data exists for the monitored vibration point A vibration point continually goes into and out of alarm The alarm sequencing does not occur per the literature A vibration point is reporting a negative or very high value The alarm light on the DX 9100 is on but no vibration point is reporting an alarm The value the vibration point is reporting never changes For example a value of 1 124 ips is being reported at all times Note Resolution The Adju2. To store trend data from the DX 9100 at an OWS define a Personal Computer PC file destination under the appropriate report access group This is required for either the direct connect or dial up VAA The direct connect VAA archives history data stored by the Metasys Point History feature and the dial up VAA archives history data stored by the DX 9100 Trend Log feature For more information about defining destinations for report access groups refer to the Operator Workstation User e Manual FAN 634 To configure Metasys report destinations 1 When defining the PC file check History under the Report types section This is done because the DX 9100 trend data is linked to the Metasys Point History feature Figure 3 shows an example of a PC file destination called REMOTE3 being defined on OWS1 REPORT ACCESS GROUP Add Destination Destination type Printer or PC e File name Destinations Files OWS1 REMOTEA Cancel Destination OWS1 Report type s N Critical l Transaction M History l Followup l Trend T Card reader T Status FTotalization Figure 3 PC File Destination Definition Example 2 Make sure the report access group chosen is under the same system as the vibration objects Figure 4 shows an example of a group called REMOTE4 defined on Metasys OWSI Vibration Alarming Application Operation 9 REPORT ACCESS GROUP ll ES Item Edit View Action GoTo Accessory Help IREPORT ACCESS GROUP SUMMAR
