Version history file power supply series PSI 9000 DT and EL 9000 DT Meaning of the symbols: + Feature added - Feature or bug removed (general bug fixes are not listed to have a better overview) * Feature changed Note: according to the block diagram in the manual, these devices have three microprocessor controlled components which have separate firmwares. They are listed below in separate sections. Note: late 2014, the PSI 9000 series have been facelifted and got an HMI with colour TFT touchscreen, which has a different firmware than the former HMI with blue LCD -------------------------------------------------------------------------------------------------------------------------------------------------- Component KE: v3.01 * First KE firmware release for PSI 9000 DT and EL 9000 DT series v3.02 + Analog interface: alarm PF (power fail) now shared with OT on pin 6 v3.03 * Various bug fixes + EL only: Support for MPP tracking (ModBus & SCPI) * OVP setting range limited to 0-103% for EL 9000 DT v3.04 - EL only: Fixed bug with SCPI commands related to MPPT function - Fixed but related to SCPI command SOURce:POWer MAX v3.05 * Improved IVI driver compatibility + SCPI: added sending termination character LF (line feed, 0xA) to all messages * Ethernet: TCP keep-alive time set to standard 2h + OT: added setting to determine whether the DC output shall be off after an OT alarm or continue + ModBus TCP: the internal Ethernet port now supports ModBus TCP via port 502, ignoring the Ethernet port setting where the default is 5025 (means, the port doesn't require to be set to 502, it's also not possible) - Removed a bug where the system would hang when the ModBus protocol is disabled, but the device receives a ModBus message -------------------------------------------------------------------------------------------------------------------------------------------------- Component HMI: v2.08 * First TFT firmware release for PSI 9000 DT and EL 9000 DT series + MPP tracking v2.15 - Reset device: fixed a bug which cause the "Reset device" not to work anymore v2.16 + "DC output after OT alarm": similar to previous already available settings, this new setting in General Settings menu enable to chose what the DC output shall be after an OT alarm, on or off (default: on) + Function to restart interface in COMMUNICATION menu, in the submenu for the particular interface. This is used to reset a supposedly hanging interface on the device side * Ethernet timeout: the Ethernet timeout can now be set to zero which deactivates the timeout, the same thing is now also done when activating setting "Enable TCP keep-alive" v2.17 * Ethernet: the Ethernet timeout is not forcibly set to 0 when activating "TCP keep-alive" -------------------------------------------------------------------------------------------------------------------------------------------------- Component DR: v1.0.4 * First DR firmware release for PSI 9000 DT and EL 9000 DT devices v1.0.5 - Removed a bug with internal flash memory v1.0.6 - Removed bug which could destroy internal memory when using the function gen
