PSB 9000 2.5 kW Series
3.6 Remote control
3.6.1 General
Remote control is possible via the built-in analog or USB port or via one of the optional interface modules (only
with standard models) or via the GPIB port (only with option 3W installed). Important here is that only the analog
or one digital interface can be in control. One of the digital ones is the master-slave bus.
It means that if, for example, an attempt were to be made to switch to remote control via the digital interface whilst
analog remote control is active (pin REMOTE = LOW) the device would report an error via the digital interface. In
the opposite direction, a switch-over via Pin Remote would be ignored. In both cases, however, status monitoring
and reading of values are always possible.
3.6.2 Control locations
Control locations are those locations from where the device can be controlled. Essentially there are two: at the
device(manualoperation)andexternal(remotecontrol).Thefollowinglocationsaredened:
Displayed location Description
- If neither of the other locations is displayed then manual control is active and access from
the analog and digital interfaces is allowed. This location isn’t explicitly displayed
Remote Remote control via any interface is active
Local Remote control is locked, only manual operation is allowed.
Remote control may be allowed or inhibited using the setting “Allow remote control” (see „3.5.3.1. Menu “General
Settings”“). In inhibited condition the status “Local” will be displayed top right. Activating the inhibit can be useful
if the device is remotely controlled by software or some electronic device, but it’s required to make adjustments
at the device or deal with emergency, which would not be possible remotely.
Activating condition “Local” causes the following:
• If remote control via the digital interface is active (“Remote”), then it’s immediately terminated and in order to
continue remote control once “Local” is no longer active, it has to be reactivated at the PC
• If remote control via the analog interface is active (“Remote”), then it’s temporarily interrupted until remote control
is allowed again by deactivating “Local”, because pin REMOTE continues to signal “remote control = on”, unless
this has been changed during the “Local” period.
