TCM® Software Release 8.4.1

M-SystemSite ServerEnterprise ServerOcular


A new form of communication is now available in TCM® software: Modbus TCP.  The communication protocol is offered via a TCM® Master device or a TCM® Slave device.

  • TCM® Modbus TCP Master allows you to pull operational values (ie. active power or similar) from non-Gram & Juhl hardware (i.e. controllers) in locations that otherwise would be inaccessible to the M-System.

Modbus Master

  • The TCM® Modbus TCP Slave allows you to receive operational values from a controller via Modbus and presents scalar measurement with their associated alarm status, bias voltage and overload status on the Modbus interface.

Modbus Slave

  • The Modbus TCP Master or the Modbus TCP Slave feature in the M-System can be activated by uploading a single license file into the TCM® server. The Modbus TCP parameters can easily be configured as virtual sensors via the ‘‘TCM® Configuration Tool’’ in TCM® Ocular.

Operational values received on either Modbus interface are fully integrated into TCM® Configuration and can be used for setting conditions for recording data (i.e. binning)

  • Both the TCM® Modbus Master and Slave functionalities are available as a per turbine license.

Site Server

  • Our Site Server software can be installed on Windows 2012 R2 servers. We have an upgrade service available for Windows 2003 and Windows 2008 platforms to Windows Server 2012.


Enterprise Server

  • The TCM® Enterprise Gateway service is now running as a system daemon allowing for faster shutdown and startup of operations.

  • The binocular icon displayed in the TCM® Ocular dashboard can now be used to localize measurements in the TCM® Configuration Tool as well as in turbine and measurement browsers.  When you focus on a specific measurement pertaining to a specific turbine in one of the graphs in Ocular, you can click on the binocular icon, and it will now, in addition to highlighting the specific turbine and measurement in turbine and measurement browsers, localize and highlight the measurement in the configuration tool.
  • You can now use color coding for different turbines or specific measurements when making a cross-site comparison. This feature is very useful when turbine data/measurements are portrayed in a waterfall plot.  Simply right-click on the specific turbine in the “Turbine Browser’’ to select a color for this turbine or right-click on the selected measurement in the ‘’Measurement Browser’’ to select a color for this measurement. See Figure 1, 2, and 3 below.

  • Ocular Diagnostic is now running faster than ever thanks to the optimization of memory storage.  We have optimized the TCM® Ocular platform by continuously freeing up memory which is not in use.
  • You can now initiate parallel requests from Ocular to the TCM® server. This is very useful when plotting trends across an entire turbine fleet: Trends will load up to 4 times faster provided your server has the processing resources required – which is typically the case in Enterprise installations. This requires a TCM® Ocular Pro license, and only works on the TCM® Enterprise Server software.
