Version history file for power supply and electronic load series PSI 9000 DT EL 9000 DT EL 9000 T PS 9000 T PSI 9000 T 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. -------------------------------------------------------------------------------------------------------------------------------------------------- Component KE: v3.09 + ModBus compliance mode: allows switching to "Full" which now makes the ModBus messages fully compliant regarding coils. The mode can be switched to remain compatible to older firmwares * Ethernet port: port 502, being reserved for ModBus TCP, cannot be set anymore in the adjustable Port register * SCPI: improved small things, like handling of the factors milli and kilo - Removed a bug when the device would return an error when setting/unsetting a coil which was already set/unset + Interface supervision: deactivated by default, it can be enabled and configured to supervise communication with the device via an user-defined timeout. If the time runs out it would switch off remote control and the DC output/input. This is valid for all digital interfaces. v3.07 * Analog interface: behavior of the DC output, when leaving analog remote control, equalized to digital remote control and depedence on setting "DC output after remote" 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 v3.04 - EL only: Fixed bug with SCPI commands related to MPPT function - Fixed but related to SCPI command SOURce:POWer MAX v3.03 * Various bug fixes + EL only: Support for MPP tracking (ModBus & SCPI) * OVP setting range limited to 0-103% for EL 9000 DT v3.02 + Analog interface: alarm PF (power fail) now shared with OT on pin 6 v3.01 * First KE firmware release for PSI 9000 DT and EL 9000 DT series -------------------------------------------------------------------------------------------------------------------------------------------------- Component HMI (DT devices): v2.18 * Various small bugs fixed + Added a setting to profiles (DC terminal after remote) v2.17 * Ethernet: the Ethernet timeout is not forcibly set to 0 when activating "TCP keep-alive" 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" v2.15 - Reset device: fixed a bug which cause the "Reset device" not to work anymore v2.08 * First TFT firmware release for PSI 9000 DT and EL 9000 DT series + MPP tracking -------------------------------------------------------------------------------------------------------------------------------------------------- Component HMI (T devices): v2.05 + New settings for DC output/input reaction after alarms (see DT series manuals) + New settings for analog interface alarm pins configuration (see DT series manuals) + ModBus complicance mode setup (see DT series manuals) * Bug fixes v2.01 * First firmware release for PSI 9000 T, EL 9000 T and PS 9000 T series -------------------------------------------------------------------------------------------------------------------------------------------------- Component DR (PSI 9000 T [device class 47], EL 9000 T [device class 48]): v1.0.6 - Removed bug which could destroy internal memory when using the function generator v1.0.5 - Removed a bug with internal flash memory v1.0.4 * First DR firmware release for PSI 9000 DT and EL 9000 DT devices -------------------------------------------------------------------------------------------------------------------------------------------------- Component DR (PSI 9000 T [device class 50], EL 9000 T [device class 51], PS 9000 T >= 1000 W [device class 56]): v1.0.2 - Fixed a bug with the wave generator. v1.0.1 * First firmware release. -------------------------------------------------------------------------------------------------------------------------------------------------- Component DR (PS 9000 T <1000 W [device class 49]): v1.0.17 + Improved the supervision functions and fixed some bugs. v1.0.16 + Improved the supervision functions, measurement functions and the storage property. v1.0.15 * First DR firmware release.
