(ESRs) and FPSOs, it provides real-time access to diagnostic information as well as data storage for offloading at a later time. Typically mounted at the end of a ring stack, the 923-EDL collects data from an array of on-board sensors and stores it in nonvolatile flash memory.

Model 923 Data Logger – User Manual 3.0 Product Description The 923-EDL card provides an array of on-board sensors and interfaces for external sensors. The card is typically installed at the factory inside Focal rotary products such as ESRs and FPSOs. With power applied to the 923-EDL, sensor data is logged automatically to on-board flash memory and simultaneously available in real time via an RS-485 serial link (J5) to a remote location.
Model 923 Data Logger – User Manual 3.1 Configuration Settings and Initial User Setup The 923-EDL cards are configured at the factory and the user does not need perform any additional card configuration settings to start operating the card and obtain diagnostics data.
The data logging interval can be set between 1 to 120 minutes and it can be changed by the user by using Focal’s GUI software through the data port J5.
3.4 On-Board Sensors The specifications for the on-board sensors of the Model 923-EDL card are given in section 2.0 of this document. The 923-EDL obtains a new sample from the on-board sensors every 5 ms. Note that the accuracy of the temperature and humidity is for the sensors themselves and corresponds to the immediate vicinity of the sensors, which may deviate from the ambient air conditions inside the rotary product.
3.5 Interfaces 3.5.1 Thermocouple Inputs The 923-EDL allows two (2) K-type thermocouples to be connected to 3 pin connectors J6 and J15. The card performs cold-junction compensation and the data output of each thermocouple is saved as an IEEE-754 32-bit floating point value in Modbus registers and also saved in the on-board flash memory.
This PCBA is designed for interfacing with a 9-pin Micro-D connector, which is used to provide power to the card and access real-time and stored diagnostics information. Top and side views of the Model 923-EDL PCBA are shown in the figure below. For more details, refer to configuration drawing 923-2004-00.
5.0 Electrical Connectors and Pin Descriptions The 923-EDL card has three (3) connectors for customer access and a few others for factory programming and testing. A 9-pin Micro-D connector (J5) on the top side of the card provides access to the diagnostics data and is also used to power-up the board.

Model 923 Data Logger – User Manual 6.0 Functionality The main function of the Model 923-EDL card is to collect data from several on-board sensors and external interfaces and store it in the on-board non-volatile flash memory. The data collected can then be used for further analysis and evaluation of the environment in which the card is installed.
6.2 Diagnostics Software 6.2.1 Overview Focal-Moog has created a sample .NET graphical user interface (GUI) to work with the 923-EDL in Modbus RTU mode. The 923-GUI (P/N: 923-0403-00) uses a serial connection to retrieve data from the 923-EDL using the Modbus RTU protocol.
4. Double click on the executable *.exe file to run the Model 923 Diagnostic Software. 6.2.3 Application Usage In order to establish a successful diagnostics connection with the 923-EDL, the card must be powered on (typically with +24V at connector J5) and the physical data communication link must be valid (also via the J5 connector).
This configuration may not apply for the current system. This could result in connection failures to the 923-EDL. It is recommended that on start-up, any existing and unknown configuration tabs are closed and new configurations are added or ensure the same configuration is always used.
6.2.4.1 Log Download The GUI gives the user the ability to offload all the data on the 923-EDL into a .csv file. The time taken for the data offload is dependent on the amount of flash memory used on the 923-EDL. An estimated time for offload is given for user convenience.

This is not a real time play-back feature. All data will be loaded in one instance for viewing. A valid serial connection with the 923-EDL is not required to use this feature. Controls for this feature can be seen in the image below.
The configuration file must be saved in .csv format. Alarm settings are saved in the local computer and are only applicable to the GUI – not the 923-EDL card. Any changes to the alarm values will only be reflected in the GUI, the 923 card will continue to operate normally regardless of the software alarm settings.
If time synchronization is enabled and a time discrepancy of greater than or equal to one (1) minute is measured, a prompt will be raised to ask the user if the 923-EDL RTC should be synchronized with the local computer (see figure below).
.xml file each time the GUI is opened. This feature is exclusively a software feature meaning the data logged to the 923-EDL will still be saved as raw analog counts. Examples of the adjusted ADC values can be seen in the images below.
