PSB 9000 3U Slave Series
3.6
Remote control
3.6.1 General
Remote control is essential when operating devices of this series, for example during master-slave. It is furthermore
possible to take over remote via one of the built-in USB ports. Important here is that only one of the digital interfaces
or a master unit can be in control. It means that if, for example, an attempt were to be made to switch to remote
control via the digital interface whilst master-slave mode is running the device would report an error via the digital
interface. In the opposite direction, the master unit could not initialise a Slave unit being in USB remote control.
In both cases, however, status
monitoring
and reading of values via any of the USB ports is always possible.
3.6.2 Remote control via the rear USB
The rear USB port offers the same set of commands as with a “normal” PSB 9000 3U device, but only while the
Slave device is not in control by a master device or currently not in status “Slave”. Then the same programming
documentation “Programming SCPI & ModBus” is valid for the user, as well as the ModBus register list “Mod-
bus_Register_PSB9000_KEx.xx+_EN.pdf”.
Control via software EPS Power Control is also possible via this port and unrestricted.
3.6.3 Remote control via the front USB
The main purpose of the front USB port is quick access to the most important DC terminal related parameters,
such as set values and protections. Reading values and status is always possible, setting them only while the
Slave device is not in control by a master device.
Outside of master-slave, the device could be controlled remotely with software EPS
Power Control
, but also from
custom applications. In order to do so, a programming documentation is delivered with the device on USB stick.
The number of available commands is restricted on this USB port, but it supports both, SCPI and ModBus RTU
communication protocols. As part of the programming documentation, there is an
extra ModBus register list
(Modbus_Register_PSB9000_Slave_Front_HMIx.xx+_EN.pdf) for the front USB port.
In the programming guide there is a section for all SCPI commands, as available with the rear USB port. Here is
an overview what commands are available with the front port. Details about the commands can be found in the
“Programming SCPI & ModBus” document, also called
programming guide
