5.2.8 Logical inputs
Logical inputs are binary signals that a user can control manually to change the behavior of the
AQ-200 unit or to give direct control commands. Logical inputs can be controlled with a virtual switch
built in the mimic and from a SCADA system (IEC 61850, Modbus, IEC 101, etc.). Logical inputs are
volatile signals: their status will always return to "0" when the AQ-200 device is rebooted. 64 logical
inputs are available.
Logical inputs have two modes available: Hold and Pulse. When a logical input which has been set to
"Hold" mode is controlled to "1", the input will switch to status "1" and it stays in that status until it is
given a control command to go to status "0" or until the device is rebooted. When a logical input which
has been set to "Pulse" mode is controlled to "1", the input will switch to status "1" and return back to "0"
after 5 ms.
The figure below presents the operation of a logical input in Hold mode and in Pulse mode.
