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 * Maximum number of sequence points (arbitrary generator) now limited to 99, which can be used all at once (before it was 100, which could not be used all at once anyway) v2.22 / v2.23 * Improved IF-AB Ethernet interface communication speed * Attention! Important change: SCPI over Ethernet now requires termination character 0xA (LF)! + Analog interface pins 6 and 14 now configurable (via ModBus or SCPI, also on HMI) to signal more alarm situation than before + Safety OVP alarm for 60 V models (PSI 9000 WR, PSI 9000 WR SLAVE and PSB 9000 series only) -> via ModBus, SCPI and on the analog interface this new alarm is indicated by "OVP" and "PF" being true at the same time - Removed a bug in master-slave (buffer overflow) which could lead to a stop of the master-slave system and interrupt contact between master and slave units v2.24 + Analog interface pins 6, 14 and 15 can now be configured to signal various statuses * Profinet: network settings (IP, subnet mask, gateway) are now ignored, because with Profinet they are usually configured via network and remote tools such as Siemens PST * Ethernet timeout can now be set to 0 to turn it off v2.25 + SCPI: Support for leading colon (":") * Ethernet timeout: the timeout can now be deactivated by setting it to 0 v2.26 * Improved parallel ramping of slaves in master-slave operation + Added ModBus command to perform "Reset device to defaults" also from remote + Added command to restart the IF-AB interface module via USB (in case it hangs or changed settings haven't been submitted successfully) * OT: the signalling of an OT alarm is now delayed for 2 s (means, the OT condition must persist for at least two seconds to be signalled) v2.27 + Profibus/Profinet: added slots/indexes for new registers (see updated register list) + OT: added setting to determine whether the DC output shall be off after an OT alarm or continue * Master-slave: improved current ramping of an MS system when swithing the DC output on(there is a natural delay between the master and the slaves) * Ethernet: enabling "TCP keep-alive" setting now forces the Ethernet timeout setting to 0, which means "off" - Removed a bug where the system would hang when the ModBus protocol is disabled, but the device receives a ModBus message * Improved SCPI setup and control of extended PV function EN50530 -------------------------------------------------------------------------------------------------------------------------------------------------- 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 v2.07 * Maximum number of sequence points (arbitrary generator) now limited to 99, which can be used all at once (before it was 100, which could not be used all at once anyway) + Safety OVP alarm for 60 V models (PSI 9000 WR, PSI 9000 WR SLAVE and PSB 9000 series only) -> via ModBus, SCPI and on the analog interface this new alarm is indicated by "OVP" and "PF" being true at the same time v2.08 + Analog interface pins 6, 14 and 15 can now be configured to signal various statuses v2.09 + SCPI: Support for leading colon v2.10 + OT: added setting to determine whether the DC output shall be off after an OT alarm or continue * Master-slave: improved current ramping of an MS system when swithing the DC output on(there is a natural delay between the master and the slaves) - Removed a bug where the system would hang when the ModBus protocol is disabled, but the device receives a ModBus message * Improved SCPI setup and control of extended PV function EN50530 -------------------------------------------------------------------------------------------------------------------------------------------------- Component HMI (LCD, discontinued) for PSI 9000 series: 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) for PSI 9000 series: 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 auto-adress error v2.13 + 60 V models (WR series): Safety OVP feature and max. voltage set value now 100% of rated value * Several small bug fixes v2.14 - Profinet interfaces: removed IP settings, since these are usually managed from a remote tool such as Siemens PST and didn't represent the true network settings after they were changed by the remote tool + Analog interface: added settings to configure the signals on output pins 6, 14 and 15. The pins can now be configured to signal: Pin 6: only "OT", only "PF", "OT" or "PF" Pin 14: 7 combinations of "OVP", "OCP" and "OPP" Pin 15: "CV" or "DC on/off" + XY generator: added option to load XY tables for FC (file name starts with FC_) and PV (file names starts with PV_) mode from USB stick, contrary to earlier version where these could only be saved - Removed possible bug: when switching back from master-slave mode (where the power would be displayed in kW) to normal mode, sometimes display of kW would remain - Removed various bugs v2.15 * Fixed bug: Setting current values of > 3000 A in master-slave systems and in function generator didn't work * Ethernet timeout: the timeout can now be deactivated by setting it to 0 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 + Master-slave: added "Rnom" to summary screen after master-slave init * 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 - Master-slave: devices slave running as slave now show an option during master-slave setup which allow to enable the HMI feature "Backlight off after 60 s", which is here directly accessible. The option shall help to protect the screen from running all the time while slaves don't show informative data. * Ethernet: the Ethernet timeout is not forcibly set to 0 when activating "TCP keep-alive" -------------------------------------------------------------------------------------------------------------------------------------------------- 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
