3. Local control interface
The local interface is a Beckhoff CP6706 Industrial PC with a touch sensitive monitor on which
the HMI of the control system is displayed.
Figure 2: The main screen
When the power supply is turned on, the operating system will boot up and show the main
screen, please see Figure 2. The main screen consists of three main areas, the right-hand
menu, bottom menu and the set and display area. In the bottom of the screen the IP address
for remote connection can be seen as well as the version of the current software running on the
PLC and the time of date.
The right-hand menu
The right-hand menu consists of four buttons and they are from the bottom the mode button,
controlling the local/remote mode of the MPS, the interlock button, showing the interlock state,
the standby button and the on button.
3.1.1. Changing the mode
The control system can be in four command modes: Local, Local Locked, Remote and Remote
Locked. When the system is in Local mode, the MPS can be controlled only from the local
interface. It is possible to ask about status on the remote line but it is not possible to set values
on the remote line. It is possible to switch to Remote mode from the local interface and also set
it in Remote mode from the remote line. When the system is in Local Locked mode, the system
can only be set in a different mode from the local interface. When the system is in Remote
Locked mode, the system can only be set in a different mode from remote.
When the system is in Remote mode it is possible to set values over the remote line and the
values will be displayed on the local interface but it is not possible set values from the local
interface.
3.1.2. Interlocks and warnings
All interlocks and warnings are displayed in the interlock list, which can be accessed by pressing
the interlock button in the right-hand menu. When there is an interlock, the interlock button is
red, when there are only warnings the button is yellow. All interlocks are latched, meaning they
will only be reset and disappear from the list after a Reset command has been issued or the
reset button, depending on what mode the MPS is in. Warnings are not latched and are

therefore only displayed while they are active. Interlocks are displayed in red text, and
warnings are displayed in red text with a star (*) in front.
Figure 3: The interlock list
The interlock list is collapsed again when the interlock button is pressed.
3.1.3. Turning the power supply on
The power supply has three states: Off, Standby and On. The power supply must first be in
Standby state before it can be turned On.
In order to turn the power supply On from the local panel, the following sequence must be
executed:
1. Set the system in Local mode by pressing the mode button in the right-hand panel and
pressing “L”.
2. Make sure that there are no faults. Faults are indicated with a red “FAULT” button in the right
panel. Press the red Faults button to view the faults in the Faults screen. Press the Reset
button to reset them.
3. Press the STANDBY button, the button will turn green when it is in standby mode
4. Press the ON button, the button will turn green when it is in On mode.
3.1.4. Turn the Power Supply Off
To turn the power supply Off, press the OFF button (it is not necessary to go through the
Standby state).
An overview if the Standby, On and Off state is shown in Figure 5. A diagram of how the states
relate to each other is indicated in Figure 4.

Figure 4 The state diagram.
Setting a current or voltage
From the main screen the current can be set by
selecting a digit and change its value using the + and
- buttons. If the MPS is in the On state, the set
current (or set voltage, see later) is changed as soon
as the digit is changed. The current is set and read in
amps by default but the software can be configured
to use PPM for the set current, in the setup screen.
When the digit is changed upward and it reaches “9”,
moving it up one more will change that digit to “0”
but the digit to the left will also increase by 1.
The set values are limited to the minimum and
maximum values indicated in the setup screen.

Settings
In order to get access to the setup screen the Setup button in the bottom menu can be
pressed.
Figure 6: The Setup window
On the setup screen the Maximum
and minimum current can be set as
well as the maximum voltage. The
user will not be allowed to set
values on the main page outside
the ranges indicated here.
Also, the control mode can be set,
current or voltage controlled. If the
control mode is set to Voltage, an
extra input field appears on the
front page allowing to also set a
voltage. Note that this is only
possible for power supplies with
implemented voltage control loop
in the regulation system. For
power supplies without this feature; use of voltage control will have no effect
The units for the set current can be set to either Amps or PPM (parts per million). If PPM is
selected the current set digits changes to a 6 digit display where 999999 ppm is 100% output
current. The read back value of the current is always in Amps. Both set voltage and read back
voltage is always in volts, please see Figure 8.

Advanced Settings
Following settings are for advanced use only. Use of strict syntax is important for the stability of
the control system.
3.5.1. The interlock file
The interlock file controls the setup of interlocks: what text should be shown and if it is a
warning or a real interlock.
The format is as follows:
PersistentData.aInterlocks[3].sDisplayText:='Water flow too low'
PersistentData.aInterlocks[3].bIsLock:=TRUE
PersistentData.aInterlocks[3].bIsWarn:=FALSE

System 8700 User Manual
Rev 0.95 Page 15 of 32
and there is a section like above for each interlock. The number in the square brackets is the
index of the interlock, please use Table 4, Table 5 and Table 6 to find out what digital input is
connected to what interlock data variables.
The variables are used as follows:
•sDisplayText: This variable sets the display text that will be shown in the interlock list in
the HMI.
•bIsLock: True indicates that this is a true interlock.
•bIsWarn: True indicates that this a warning.
bIsLock and bIsWarn cannot be true at the same time.
It is very important that the format and the order of the file is maintained. The software that
reads the file on the PLC requires a specific syntax to read the file. It is not allowed to make
comments in the file. It is not allowed to add extra white spaces in the file.
3.5.2. Editing the files
Basically there are two ways to edit the file:
•FTP. Use a normal FTP client to connect to the PLCs IP address and use the user name
“Danfysik” and password “Danfysik”. Navigate to the directory /root-www/Recipes and
download the required file. Edit the file and upload the file again.
•Local editor. On the local monitor go to the Windows Start menu as described in section
4.4.1 and Click Run and type in “notepadce”. In the NotepadCE program click File/Open and
navigate to \Hard Disk\WWW\Recipes\ and load the required file.
4. Remote control interface
The MPS can be controlled remotely either via ethernet or via RS232.
Ethernet interface
The remote communication interface is TCP/IP, via the RJ45 connector marked LAN2 in the
bottom of the Beckhoff CP6706 IPC (Industrial PC), please see Figure 10. Please note that there
are two RJ45 connectors on the IPC, the one marked “LAN1” in Figure 1 is for the
communication to the I/O modules.
Figure 10: The connections on the Beckhoff CP6706 IPC

Page 16 of 32 Rev 0.95
Serial RS232 interface
To be described
Remote control commands
There are two sets of commands for controlling the MPS, SCPI commands and a subset of the
commands used for the older models of the Danfysik MPS.
4.3.1. SCPI commands
The SCPI communication protocol is based on the IEEE standard “Standard Commands for
Programmable Instruments” (SCPI) but only a subset of commands is implemented. The
definition of the standard can be found here:
http://www.ivifoundation.org/docs/scpi-99.pdf
However, this is rather lengthy and an easier to read example of how it can be implemented
can be found here:
http://www.us.tdk-lambda.com/hp/pdfs/product_manuals/83034100.pdf, please see
page 35-45.
In short, SCPI is a standard set of commands implemented by many of the major instrument
companies, making it much easier to implement different instruments in software.
Most SCPI commands, but not all, have “set” version and an “ask” version. Example:
•The command “OUTP:CURR 22.56” sets the current to 22.56 amps.
•The command “OUTP:CURR?” asks for the current set value and will return “22.56”.
The computer uses port 13000 for the SCPI communication.
The implemented commands are listed in Table 1.

4.3.1.1. Status reporting
The status reporting is done via the OPERation status register with the command
STATus:OPERation. The different status, warnings and errors are split up in separate arrays,
see below. The array is summed up on the level above with an “or” so that if one or more bits
are set in an array, the bit on the level above will also be set. New sub commands have been
constructed to get the individual sub arrays e.g. to read the status bits in register 1, the
command STATus:QUEStionable:REG1 is used.
In the tables below the Bit indicates what bit the signal corresponds to after the decimal
number returned by the command has been converted to a binary digit, see also the example
after Table 6 for further explanation. The Input column indicates what digital input the signal is
connected to. If no input is indicated the signal is generated internally.
