Version history file for 2014 released power supply series PSI 9000 2U / 3U / 15U / 24U PSI 9000 3U SLAVE 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: v2.01 * First KE firmware release for PSI/ELR 9000 series v2.03 * Optimized the start procedure to take less time v2.04 * Improved the tabular value speed (XY generator) v2.06 * Modified the master/slave mode, improved Anybus interfaces init and speed v2.07 * Improved USB SCPI/ModBus communication + Remote PV function control via digital interfaces v2.08 + Remote activation/deactivation of the communication protocols * Improved the IF-AB RS232 module init and handling v2.11 * Improved master-slave operation for slave units where an Anybus interface module is installed * Improved response time of digital interfaces to ~3 ms * Improved sample rate of analog interface to 500 Hz, i.e. sampling of set values (VSEl, CSEL, PSEL, RSEL) + Introduced adjustable Ethernet timeout (5-65535 s, default is 5 s) v2.12 + Support for new CAN interface IF-AB-CAN + Commands (SCPI & ModBus) to configure upcoming CAN interface IF-AB-CAN remotely v2.13 + Cyclic data transmission for CAN interface IF-AB-CAN v2.14 * Master-slave: overall performance improved + Master-slave: added resistance control (R mode) --> affects all PSI 9000 (from 2014) and EL/ELR 9000 series --> must have HMI 2.07 update for manual operation of R mode v2.15 + Ethernet: Keep-alive function added to socket connection, including support for remote setup of keep-alive time * Improved CAN performance + Analog interface: added reporting alarm "power fail" (PF) on pin 6 (OT), so the pin is shared now v2.16 - Settings: Fixed bug where devices with KE 2.14 or higher would occasionally or every time lose all settings and start up with factory defaults - Master-slave: Fixed bug where slave units would reset their Ethernet settings (for monitoring) when being under control by the master unit * Master-slave: Boot time extended for master-slave devices so the master has sufficient time to enumerate slaves being powered a little later, like in situations when slave units are powered one by one, but after the master units, opposite as it is supposed to be - CANopen: Fixed bug where three SDOs would not be accessible as soon as the CANopen node is switched to operational mode v2.17 * IF-AB interfaces: fixed problem with 1 & 2 port Profinet modules v2.18 - Function generator: fixed a bug where certain functions would not draw/provide current when being applied to current * CANopen: increased number of supported objects. Now both function generators are implemented. New EDS file available as download. - SCPI: fixed parameter MAX for use on some SOURCE: commands, such as VOLT. The parameter now respects limit settings correctly. Rules: VOLT, CURR, POW, RES: MAX sets maximum allowed voltage, either 102% or U-max / I-max / P-max / R-max OVP: MAX set 103% voltage for load deviced and 110% for power supplies OPP, OCP: MAX sets 110% of current or power v2.19 + Photovoltaics: added commands (SCPI and ModBus) for PV test mode according to DIN EN 50530 * Actual current values <0,2% of Inom not indicated/readable anymore v2.20 * Improved PV DIN EN 50530 function regarding TCP streaming, stability and performance -------------------------------------------------------------------------------------------------------------------------------------------------- Component KE for GPIB models: v2.02 - Fixed bug with command SYST:LOCK over GPIB where it was not executed as expected v2.03 - Some small bug fixes 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 -------------------------------------------------------------------------------------------------------------------------------------------------- Component HMI LCD: v2.01 * First LCD HMI firmware release for PSI/ELR 9000 series v2.02 + PSI only: added manual photovoltaic (PV) and fuel cell function v2.03 * Modified fuel cell curve calculation in master slave mode, increased max. frequency for since wave function v2.04 + Alarm history menu, "Analog interface Rem-SB" and "Analog Rem-SB action" settings, "DC output after PF" setting * Improved master-slave mode, improved device calibration -------------------------------------------------------------------------------------------------------------------------------------------------- Component HMI TFT: v2.01 * First TFT HMI firmware release for PSI/ELR 9000 series v2.03 + Added Chinese and Russian as selectable GUI language + Added PIN code setup and requester for HMI lock * Changed display format of resistance set values to always 5 digits - Fixed some bugs v2.05 + Configuration for upcoming CAN interface IF-AB-CAN v2.07 * EL 9000 B: Reduced adjustable OVP level for EL 9000 B series to 103% due to technical reasons + Master-slave: added resistance control (R mode) --> affects all PSI 9000 (from 2014) and EL/ELR 9000 series --> must also have KE firmware 2.14 update * Master-slave: all adjustable values are now related to the master-slave system --> internal per cent system works in any situation where the master-slave system could change due to a changing number of slaves. Example: two 510 A models in MS with setting 720 A (60%). No the slave fails or connection drops. Master is re-initialised, slave still broken, master can only do 510 A, so the current setting reduces to 60% of 510 A, which is 360 A. + Master-slave: added auto-enumeration for PSI 9000 Slave devices (new in spring 2016) v2.08 + Support for writing CSV files to USB stick in US format + Support for EtherCAT interface (not settings here, though) + New start screen for language selection * ModBus TCP interface: since port 502 is reserved for ModBus TCP protocol, changed port setting so that port 502 for normal TCP access cannot be submitted v2.09 + USB logging feature + Setting for TCP keep-alive + Models with <1000 W nominal power: added decimal place to power values (set and actual) v2.10 + USB logging: CSV file format settings added - USB logging: removed bug that could occur if R mode is active v2.11 + Photovoltaics: added PV test mode according to DIN EN 50530 - Removed various bugs v2.12 * CANopen: node address in LSS mode now set to 255 upon errors -------------------------------------------------------------------------------------------------------------------------------------------------- Component DR: v1.6.0 * First DR firmware release for PSI/ELR 9000 devices v1.6.3 / v1.6.4 * Improvements v1.6.5 - Fixed bug which led to "No DR found" error, which is shown during start and which caused several unexpected actions like OVP or the power stage(s) not working
