TCM® Software Release 8.6.2
- Gram & Juhl’s normal 2-minute recording cycle can now be extended to allow for the collection of more measurements or measurements which are best sampled when extended over a longer period (i.e. low-frequency measurements or sampling of measurements while running in curtailed mode). This allows our customers to make adequate analysis for specific measurements. Please note that recording time should not be extended unless adequate memory is available (Memory usage can be checked by reviewing the ”Memory Usage” measurement which is part of the ”System Monitor” sensor in TCM® Ocular, but only if this sensor has been configured).
- Gastops’ MetalSCAN 3000 sensor is now fully supported as part of the TCM® Compliance Program. If you desire to combine oil monitoring analysis with vibration analysis, contact firstname.lastname@example.org to obtain a sticker with a license key for each MS3000 sensor you desire to couple to the TCM® system. The MetalSCAN 3000 sensor is configured using the ”TCM® Configuration Tool” in the TCM® Ocular software program. You can configure masks based on the number or frequency of metal particles in the oil, so that alarms will be triggered within the TCM® system indicating rotating equipment bearing or gear damage. Contact email@example.com if you would like to obtain an excerpt from our manual on commissioning and configuration of the MS3000 sensor.

- Support for rogowski coil now also allows for measuring active power and power quality measurements. Active power can even be measured with variable line frequency. Active power is a key operational value for binning measurements. The rogowski coil is simple to use and can be easily configured—simply wrap it around the power cable and snap it in place, then you can configure the active power measurement in the TCM® Configuration Tool in TCM® Ocular.

- The Site Server now fetches turbine data from each M-System every 10 minutes. Before this release, data was fetched every hour. This improvement allows our customers to react faster to alarms, moving a step closer to ”real-time” monitoring.
- Much like the Site Server update, the Enterprise Server now fetches turbine and alarm data from each Site Server every 10 minutes. Before this release, data was fetched every hour. Again, this improvement allows our customers to react faster to alarms, moving a step closer to ”real-time” monitoring.
- The original OPC UA license has now been replaced with the upgraded OPC UA IEC license, which models wind power plant data according to an expected revision of the IEC 61400-25-6 standard, which will include modelling of condition monitoring data. The TCM® OPC UA IEC Server is now available as a licensed functionality per WTG. With the OPC UA IEC Server, you can extract both measurements and alarms from the TCM® system and integrate them into your SCADA system or use the data in other third-party analysis programs (i.e. PI®, or SmartSignal® ). The OPC server essentially pulls information from the TCM® server(s) with which it is connected. The OPC UA IEC Server functionality is maintained as an integral part of the TCM® software, and is only offered on Enterprise servers. You can request a manual for OPC at firstname.lastname@example.org.

- After popular demand, we have brought back the original waterfall perspective once used in the TCM® Data Mining Tool. This perspective is now called the ”Waterfall” view in TCM® Ocular and the previous waterfall plot is now called ”3d view.” Ocular users now have the option of viewing 3D data in the 3dView, Waterfall, Contour or Overlay plots. At Gram & Juhl, we pay special attention to all customer requests that we receive, so if you have any new feature requests, please let us know at email@example.com.

- A contour view has now been added to the multiplot. By using the contour view, Ocular PRO users can get a quick overview of prevailing tendencies seen at differentiating heights, or measured accelerations. Because the contour view looks at the graph from above, higher accelerations will be depicted using a brighter color, so that they are easily recognized at first glance. In fact, there is a color chart based on acceleration, which helps users to pinpoint key trends.

- You can now track and untrack measurements for line and multi plots. By tracking measurements, you are able to sample measurements, so that they are running with the same RPM. One prime example of why tracking measurements is beneficial is with the case of the overlay plot. In an overlay plot, values are shown from the side, so when you track measurements, you can more easily identify abnormalities within the plot. To the contrary, untracked measurements are helpful for pinpointing measurements that are independent of RPM (e.g. electrical frequencies).
- Ocular now supports https client certificates. This allows for building a secure TCM® infrastructure. This feature is one of the many features we have developed moving us one step closer to helping our customers adhere to the requirements of NERC CIP.
- We have introduced an all-new plot called the Orbit Plot. The orbit plot can be made on a two-dimensional synchronous time server, so it is optimal for all types of measurements where you have both X and Y measurements. The plot itself is essentially a scatter plot between X and Y showing top markers. The plot’s usage is ideal for checking if a shaft is misaligned on a rotating bearing. However, it can also be used to indicate oil/fluid instabilities, rubs, loose parts, and shaft cracks. You will usually find an orbit plot to be depicted as a circle or an ellipses, but the different shapes shown will depend on the forces on the shaft.
*This feature is only available in Ocular Pro.
