Remote control
3.5.1
General
Remote control is possible via one of the built-in interfaces (analog, USB, Ethernet) or via one of the optional in
-
terface modules. 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 an attempt was 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. However, status monitoring and reading of values are
always possible.
3.5.2
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 defined:
Displayed location
Description
Remote: None
If neither of the other locations is displayed then manual control is active and
access from the analog and digital interfaces is allowed.
Remote: <interface_name>
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
). 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.
Activating condition
Local
causes the following:
•
If remote control via the digital interface is active (e. g.
Remote: USB
), 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is no longer active, it has to be reactivated at the PC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: Analog
), 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.
