T8013

Features:

• Serves as the Data Acquisition Link Between the Trusted Controller Communications Interface and Engineering Workstation
• Unifies Discrete Sequence Of Events Timestamping with Analog Process Historian Variable Recording
• Coordinates with Trusted I/O Modules and System Processor Architecture for Millisecond-Resolution Data Capture

The T8013 operates as the Sequence Of Events & Process Historian Collector Package in a Trusted system environment, generating time-stamped logs of all discrete state changes and recording analog variables for comprehensive operational monitoring. It continuously collects data from the controller via the communications interface module, utilizing either the serial or Ethernet ports on the rear panel to establish the data transmission pathway (the front serial port cannot be used for this purpose). Seamless data acquisition is standard with the T8013, and initiating multiple SOE and PH displays will enable concurrent gathering of information from multiple Trusted systems without interruption. The T8013 achieves true 1ms timestamp resolution directly from the I/O modules regardless of application scan time, representing a significant advancement in temporal accuracy over conventional processor-dependent logging methods.

The T8013 provides essential data collection functions critical to the entire Trusted system monitoring architecture, and is a vital component of the analytical pathway, directly supporting accurate incident reconstruction and proper operational review of the overall control system. One T8013 disk is required per installation, with the software package operating from the engineering workstation rather than occupying physical rack slots. The T8013 is always deployed in conjunction with the Trusted communications interface module, which manages the 4,000-entry log buffer while the processor retains the most recent 1,000 entries.

For concurrent multi-system monitoring applications, the Trusted system architecture supports multiple T8013 SOE and PH displays initiated from the engineering workstation. In addition to standard single-system data collection, this multi-display configuration also performs simultaneous gathering of discrete events and analog variables from several Trusted controllers. The T8013 collection mechanism executes data acquisition using the true 1ms timestamping resolution provided by the Trusted I/O module internal circuitry. Using this method, the system continually monitors and logs all discrete changes of state—such as faults, field trips, and output actions—and analog process variables. If the communications interface module detects that the log has reached its 4,000-entry capacity, it will automatically overwrite older data in the scrolling buffer while the processor maintains the most recent 1,000 entries, ensuring no data loss occurs provided the T8013 collector remains connected and actively gathering.
