TCM® Software Release 8.5.1
- The TCM® system now provides an even better overview and centralization of all of your turbine’s data, not just vibration. Operational values such as wind speed or active power can now be traced directly from your M-System, with a new measurement type, called ”OperationalValueTrace’’. This new measurement type traces operational value typically sampled once every second, so that you are able to track real-time variations in operational data.
- General performance improvements
- Detailed syslog messages from the Site server can now be found directly on the Enterprise server under the ‘’Fault Handling’’ menu on the ‘’System Logs’’ page. Syslog messages are extremely important messages corresponding to system faults, system emergencies, system warnings, system information and M-System information. So, if there is a ‘’Database Full’’ or ‘’Commissioning not OK’’ message on your Site server, you will not only be alerted via your Enterprise server, but you will be provided with an action to remedy the problem, allowing for full integration of TCM® operations.*Syslog messages prior to this release were only provided via the ‘’Performance’’ page and the ‘’Replication Status’’ page and only contained minor details about the fault.
- The TCM® measurement SOAP web service is now obsolete. This service is still working, but is no longer being maintained and will eventually be removed completely. Instead, TCM® users will need to use the RESTful interface for use of third-party analysis programs. The RESTful interface provides better security control and gives you access to binned vibration data (measurements) along with selected operational values available from your M-System, like power bins, wind speed, RPM, etc. RESTful allows you to extract historical measurements as well.
Contact firstname.lastname@example.org to obtain a RESTful license for access to TCM® Data, Alarm, or Configuration information.
Here is a brief overview of the licenses offered:
- Let Gram & Juhl support you in your ambitions of having a High Availability setup. We have put the architecture in place to help you achieve your goals of having test and fail over servers in combination with the Enterprise server software solution. Gram & Juhl has now documented its solution for the High Availability Enterprise server setup in the ‘’TCM® Enterprise Technical Reference’’ manual. In order to implement a cluster setup, you will need to choose between a CLVM or DRBD storage service, and we will work together with you with the implementation to make sure that you have a secure Enterprise solution that meets the demands of your company’s IT policies.
- It is now possible to see all historic measurement configurations within TCM® Ocular. This means that if you, for example, mount a sensor in a period to try to catch a fault pattern and then eventually remove the sensor, you will still be able to find this measurement configuration. “Once you have a turbine selected in Ocular, you can look at a particular measurement, and in the ‘’Found’’ column, you will typically see ‘’Database , Configuration’’ However, if you only see ”Database’’ mentioned in the ‘’Found’’ column ’’, this means that this is a historical measurement configuration.”
- Information about nominal measurement duration and applicable RPM limits are now given interactively while configuring measurements. When you change any settings, such as the number of measurement samples, the Nominal Measurement Duration, Minimum RPM, and Maximum RPM will be altered in the TCM® Configuration Tool as shown in the highlighted fields below. Please note that issues that must be remedied will be indicated in red text.

- A new mask trend feature has been developed, so that now you are able to see graphs of yellow and red mask values as a function of time in trend plots. Different messages for these masks are also displayed in these trend graphs. This feature helps to give you a better idea of when a yellow or red mask could be surpassed, thus triggering a yellow or red alarm.

*This feature is only available in Ocular Pro.
