3.5 Remote control
3.5.1 General
Remote control is possible via the built-in analog or USB port or via one of the optional interface modules. Important
here is that only the analog or one digital interface 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 analog remote control is active, 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.
3.5.2 Controls locations
Control locations are those locations from where the device can be controlled. Essentially there are two: at the
device(manualcontrol)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 control location is not 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 “„3.4.3.1. Menu “General
Settings”“). In inhibited condition, the status “Local” will be displayed top right. Activating the lock can be useful
if the device is remotely controlled by software or some electronic device, but it is 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 is 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continue remote control once “Local” is no longer active, it has to be reactivated at the PC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 is 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.
