Appendix C: RPM-416 Software Version History

This appendix provides a complete history of firmware versions for the RPM-416 Data Logger.

VersionDateDescription
v2.614/03/2025Increased transformation factor for channels 4,5,6,7 from 2000 to 9999. Optimized speed for the data acquisition task.
v2.507/02/2025Fixed incorrect scaling of channel 11 in the Web-interface.
v2.405/08/2024Fixed incorrect user offset for temperature channel 2. Fixed inverted menu for channels 12, 13, 14, 15.
v2.319/01/2024Resetting user settings (pressing the UP and DOWN buttons) has been moved. Added a delay after inserting a disk (to stabilize the power supply).
v2.231/05/2023Added Ethernet reboot function if Link is out of service for more than 60 seconds. Input event values are normalized (example: 255.0 V, 12.44 A).
v2.102/05/2023Fixed the calculation of the power value.
v2.002/05/2023Fixed and optimized SPI IO. Added new code for FTP server. Optimized graphical interface. Fixed 1920→1480 points and SRAM 1 and 2 sizes. Optimized memory usage. ARP timer resolution changed from 5 to 1 second. Added Modbus server timeout checking using the timestamp in absolute value. Ethernet DMA has been optimized. Fixed algorithm for saving settings and calibration. Fixed PHY and ETH synchronization.
v1.928/07/2022Optimized for the new GD32F107VCT6 MCU. Fixed blocking of flash memory after writing. Fixed reading data via SPI.
v1.827/10/2020Data recording loss at maximum speed (1ms) is fixed.
v1.708/04/2019Casual reset of the device in mode of sitting is corrected.
v1.621/12/2018Formatting of the memory card is corrected.
v1.503/08/2018The event counter has been added when the power was applied to the device, as well as the time of recording the last event (registers 23:24 and 25:26). Added the ability to save (load) all settings to a memory card. Changed the scaling of analog channels (10 and 11), now it is necessary to set the input and output range of values. The FatFs file system library has been updated to version 13b. Improved the password entry screen. Corrected the error #5 when recording events in the ring mode. Optimized the SPI frequency to support slower cards. Time synchronization with PC has been optimized. Optimized the display of measured values on the front panel. Optimized the algorithm for determining the Ethernet cable connection. Corrected a critical error that caused the device to reboot. General system performance improvements.
v1.411/04/2017Line voltage measurement has been added (channel 19). Corrected the scaling of analog signals (channels 10 and 11). Improved the time correction to 99.9 s per day. Fixed hang-up of Ethernet DMA when pinging the device in large packets of 65,500 bytes.
v1.321/07/2016Added scaling of analog signals for channels 10 and 11. Electric power meters have been added. Counters of discrete signals have been added. Added the ability to change the password from the front panel (Modbus, Ftp, Http). Modbus network identifier has been added. Corrected the removal of old files in the write mode by the ring.
v1.228/07/2015Added measurements: harmonics of voltage and current, peak values of voltages and current. Added the support for expansion modules. Added the ability to connect to the server Overvis. Completely rewritten protocols: Modbus, Ftp and Http. Improved the correction of the real-time clock.
v1.112/11/2014The folder names have been corrected when working with FTP. Minor corrections.
v1.030/08/2014The first version of the software.

To check the current firmware version of your RPM-416:

  1. Navigate to Menu → Device version on the front panel display
  2. Or read Modbus register 1 (firmware version)
  3. Or check the Device version section in the Web-interface
