6.2 Digital Interface PROBUS V (Option)
The flexible Interface System Probus V consists of two parts, that communicate over a
fiber optic connection.
Unit ADDAT30 (short “ADDA”) is an AD/DA interface that controls the power
supply. ADDA is connected to an interface converter via fiber optics. ADDA is
located as a plug on module on the power supply electronics. It is accessible
after opening the left side panel of the housing.
The interface converter that connects ADDA to different bus-systems, is
located at the back panel of the power supply.
It can also be operated outside the power supply. In that case, the outside
connection is fiber optic and therefore, a maximum of EMC ruggedness can
be achieved.
At the moment, interface converters are available for the following bus-systems:
USB
IEEE-488
LAN (Ethernet)
RS232
RS422
RS485
Profibus
CANopen
Analog 0..10V
Features (short form)
“Probus V” provides commands to set output voltage, output current and to switch the
output voltage.
Set values can be ramped with defined speed.
High resolution read back of actual values.
Programming speed
Up to 2000 set values per second possible. (depending on the interface converter)
Select Digital Interface
Set switch (4) to REMOTE.
If the power supply is additionally equipped with an “analog programming” option, set
also switch (5) to DIGITAL.
LED DIGITAL (8) indicates digital programming selected
Status indication
LED BUSY (9) flashes on data traffic.
Voltage limitaion
The voltage set value limitation is always active. Adjustable with Potentiometer V-
LIMIT (17) on the front panel.
Further Information
A detailed description of the Probus V system (command set, driver installation etc.) is
provided in separate manuals that come along with Probus V.
