Version history file for 2014 released power supply series PS 9000 1U PS 9000 2U PS 9000 3U 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. This is valid for all digital interfaces. v3.06 + 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 - Fixed bug related to SCPI command SOURce:POWer MAX v3.01 + Added keep-alive functionality for the Ethernet port (register 10007 resp. SCPI command SYSTem:COMMunicate:LAN:KEEPalive) v2.07 + Improved analog interface sample rate to 500 Hz v2.06 + Remotely adjustable Ethernet timeout v2.04 + Remote activation/deactivation of the communication protocols v2.03 * Improved the USB SCPI/ModBus communication v2.01 * First KE firmware release -------------------------------------------------------------------------------------------------------------------------------------------------- Component KE for GPIB models: v2.10 + OT: added setting to determine whether the DC output shall be off after an OT alarm or continue - Removed a bug where the system would hang when the ModBus protocol is disabled, but the device receives a ModBus message v2.09 + SCPI: Support for leading colon v2.08 + Analog interface pins 6, 14 and 15 can now be configured to signal various statuses v2.04 - Settings storage problem fixed + Alarm Power Fail (PF) indicated along with OverTemperature (OT) on pin 6 of analog interface - GPIB address: Fixed bug where the address could be set to 31 via USB command - SCPI: removed some CAN interface related commands from list of supported commands * Improved performance on GPIB v2.03 - Some small bug fixes v2.02 - Fixed bug with command SYST:LOCK over GPIB where it was not executed as expected -------------------------------------------------------------------------------------------------------------------------------------------------- Component HMI (with blue LCD, discontinued): v2.04 + Manually adjustable Ethernet timeout, HMI PIN lock, user text now displayed on "About HW, SW" screen v2.03 + "DC output after PF alarm", manual or remote activation/deactivation of the communication protocols, USB timeout settings, - Voltage controller speed setting * "General-Settings" arrangement v2.02 + Alarm history menu, "Analog interface Rem-SB" and "Analog Rem-SB action" settings * Improved device calibration v2.01 * First HMI firmware release for PS 9000 2U/3U models -------------------------------------------------------------------------------------------------------------------------------------------------- Component HMI (with color TFT): v2.05 + New setting: ModBus compliance mode (under Communication) + New setting and feature: Interface monitoring (short explanation: can stop the device from supplying power if digital remote control line is interrupted) + New GUI languages: Spanish and French - GPIB: removed a bug with setting and storing the GPIB address v2.04 + New setting "DC output after remote" (used to define the DC output condition after leaving remote control mode) v2.03 + Added new setting "DC output after OT alarm" + Analog interface pins 6, 14 and 15 can now be configured to signal various statuses (this also requires to update the KE firmware to 3.05 or higher) * Ethernet: the Ethernet timeout is not forcibly set to 0 when activating "TCP keep-alive" v2.02 - Removed bug which caused the power LED on the front to stay orange after boot v2.01 (first official release) -------------------------------------------------------------------------------------------------------------------------------------------------- Component HMI of 1U devices (blue LCD): v2.06 + New setting: ModBus compliance mode (under Communication) + New setting and feature: Interface monitoring (short explanation: can stop the device from supplying power if digital remote control line is interrupted) v2.05 + Setting "DC output after remote" + Setting "DC output after OT alarm" + Configuration of analog interface pins 6, 14 and 15 (the default settings for these pins are the same as before this update) + Ethernet setting for TCP keep-alive (shall prevent to close socket connection on the device side when the Ethernet timeout elapses) * Stabilized digital interface communication -------------------------------------------------------------------------------------------------------------------------------------------------- Component DR: v1.0.21 * Bugfix: Power fail alarms were not displayed after the start of the device and when being already present during the start v1.0.18 * Improved device calibration and the supervision functions v1.0.17 * Improved the supervision functions v1.0.16 * Improved the supervision functions, measurement functions v1.0.15 * First DR firmware release
