3.4 Remote control
3.4.1 General
Remote control is principally possible via the built-in analog or USB port or via one of the optional interface mod-
ules (AnyBus CompactCom). 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 (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.
3.4.2 Controls locations
Control locations are those locations from where the device is control. Essentially there are two: at the device
(manual control) and outside (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 is not explicitly displayed
Remote Remote control via interface is active
Local Remote control is locked, only manual operation is allowed.
Remote control may be allowed or locked using the setting “Allow remote control” (see “„3.3.3.1. Menu “General
Settings”“). In a locked 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 the lock and status “Local” causes the following:
• If remote control via the digital interface is active (“Remote”). then remote control is immediately terminated and
must be reactivated at the PC once “Local” is no longer active.
• If remote control is via the analog interface is active (“Remote”) then remote operation is only interrupted until
remote control is allowed again, because pin “Remote” continues to signal “remote control = on”. Exception: if
the level of pin “Remote” is changed to HIGH during the “Local” phase.
