Meaning of the symbols:
+ Feature added
- Feature or bug removed
* Feature changed

Note: only important corrections and additions are listed here, history starting from version 4.04

v4.04
- PS 8000 2U/DT: removed a bug where the Preset UVL mode would exit automatically
- PS 8000 2U/DT: removed a bug where the setup menu would occasionally display unwanted settings for the various interface cards
- PS 8000 2U/DT: removed a bug that did not show device node setting for IF-E1 card (used for USB port)

v4.05
+ PS 8000 2U/DT/3U: added Profibus card support
- PS 8000 2U/DT/3U: removed a bug where the set values were not settable to 100% when changing to FINE -> changing value -> changing back to COARSE

v4.06
* PS 8000 T: Display of device model during startup replaced by display of software version ("SoFt"), because the device software version can not be seen elsewhere except via interface card;
             software version is also displayed after return from STANDBY mode
+ PS 8000 T: New setting in device setup: "PbAd" -> Profibus address setting from 1 to 125
- PS 8000 T: Removed flickering of LED display
+ PS 8000 T: New setting in device setup: "brtn" -> Brightness setting for the LED display in 4 levels
+ PS 8000 T: Interface card information added to device setup menu: scrolling through to "InFo" now shows 
			 1. name of plugged interface card (short form like C1 for IF-C1 etc.)
			 2. card software version, if available (applies to IF-E1, IF-G1 and IF-PB1)
- PS 8000 T: Removed a bug where returning from shutdown, while external control was active, led to inactive voltage setting encoder
* PS 8000 2U/DT/3U: Changed display of interface card type in device setup menu. The card name is now displayed in the 3rd row of the right side and the interface card software version
                    (applies to IF-E1, IF-G1 and IF-PB1) is displayed in the 4th row
+ PS 8000 T: Display refresh of actual values is now reduced in order to avoid heavy changing of the last digit
- PS 8000 2U/DT/3U: Removed a bug where it was possible to switch the output off by pin REM-SB (analogue interface) even in LOCAL mode, so that the conditions were confused
- PS 8000 T: Removed a bug where LOCK condition would not lock the encoders after return from STANDBY
* PS 8000 T: Improved rotary encoder sensitivity when rotating slowly, because in former versions the encoders may occasionally "jump" values

v4.07
- PS 8000 2U/DT/3U: Removed a bug where the device could not be set into remote control after the user activated the SETUP menu
- Removed a bug where the device would return communication error code 0x01 (parity error) when writing to a read-only object; this miscontrol now creates error 0x09 (read/write law hurt)

v4.10
- PS 8000 DT/2U/3U: Removed a problem, where the undervoltage limit (UVL) was not initialised correctly after booting
  Note: if an UVL limit was set and the device was switched off while being in remote and it will store the last set values, the set value is restored after the next boot and the UVL limit
  will only start effecting the voltage set value next time it it changed
  
v4.11
- PS 8000 2U/DT/3U: Added object 37 to remotely set the UVL (undervoltage limit), see updated object list

v4.12
- PS 8000 T: the device will now store the last set values and output condition when being switched to standby and then switched off (mains switch/mains blackout) and restore both of them

v6.03
+ CAN users: added switching between our old CAN ID system and the new, Vector DBC compatible ID system (see updated user manuals for details)
* Made LOCAL explicite: if LOCAL is activated, any remote control from digital or analogue interface is interrupted and the unit can be controlled manually as usual, as soon as LOCAL is
  left, analogue remote control becomes active again (if present) and digital remote control has to be activated again
* DT/2U/3U: Display refresh now slower (300ms) so that actual values do not vary too much anymore
* DT/2U/3U, setup: "Node" --> "Device node"
* T model with IF-C1 card: Corrected display of bus termination setting where "off" and "on" were interchanged
- Removed bug where the preset values showed wrong after returning from analogue or digital remote control
- Removed bug which caused output voltage and current to be non-linear when controlling the unit via analogue interface in 0...5V range
+ LOCK condition is now stored when switching the device off by mains switch and restored after power-on

v6.04
- Removed bug where in some occasions and models with power adjustment the power set from analogue interface (PSEL) was not measured correctly

v6.05
- DT/2U/3U: Removed bug where the LOCAL LED was cleared when leaving Preset mode automatically after 5s, but LOCAL was still active and preventing remote control

v6.06
* FINE mode, if being active, is now deactivated as soon as the device is switched to remote control (FINE condition belongs to manual adjustment only)

v6.07
- Removed bug where the set values for voltage and current could not be adjusted (always "jumping" back to 0) as long as "AI range: 0-5V" was selected in the setup
* Pin REM-SB (remote standby, i.e. output off) of the analog interface will now also be affective in remote control via digital interface, in order to match the documentation --> the output
  can be switched off by a contact on REM-SB in case of emergency, no matter if remote or manual control, but except LOCAL is active

v6.09
- T: Removed bug that caused the device to set the wrong internal set value when switching from remote control (analog or digital) to LOCAL mode
- Saving of memory sets corrected: new values sent via objects to the device were formerly not saved, instead the old ones were saved.
- Limits of the values of memory sets corrected: when sending set values for memory sets, the limits were before checked against the currently active set values, not withing the memory set itself

v6.10
* Analogue interface: made signal CV only indicate constant voltage regulation if truely CV is on and the output is on

v6.11
- LOCK mode: made explicite. LOCK mode is now correctly restored after switching the device on. Activating LOCK mode aborts any preset mode and memory mode.
* PRESET mode: Preset is now aborted when switching to remote control while being in preset display, else the preset display would not exit automatically
 
v6.27
* Update fix: when updating firmwares up to 6.11 to any higher version up to 6.26, the device might stop working -> this is fixed in this version

v6.28
- PS 8000 T (HS): fixed a bug concerning the Shutdown mode, where OVP could occur with some devices when returning from Shutdown
