The Control Input commands can be found in the ‘Control Input’ menu. In the ‘Ctrl.
Ι
/P
status’ menu cell there is a 32 bit word which represent the 32 control input commands. The
status of the 32 control inputs can be read from this 32-bit word. The 32 control inputs can
also be set and reset from this cell by setting a 1 to set or 0 to reset a particular control input.
Alternatively, each of the 32 Control Inputs can be set and reset using the individual menu
setting cells ‘Control Input 1, 2, 3’ etc. The Control Inputs are available through the relay
menu as described above and also via the rear communications.
In the programmable scheme logic editor 32 Control Input signals, DDB 160 to 191, which
can be set to a logic 1 or On state, as described above, are available to perform control
functions defined by the user.

The “CTRL. I/P CONFIG.” column has several functions one of which allows the user to
configure the control inputs as either ‘latched’ or ‘pulsed’. A latched control input will remain
in the set state until a reset command is given, either by the menu or the serial
communications. A pulsed control input, however, will remain energized for 10ms after the
set command is given and will then reset automatically (i.e. no reset command required).
In addition to the latched/pulsed option this column also allows the control inputs to be
individually assigned to the “Hotkey” menu by setting ‘1’ in the appropriate bit in the “Hotkey
Enabled” cell. The hotkey menu allows the control inputs to be set, reset or pulsed without
the need to enter the “CONTROL INPUTS” column. The “Ctrl. Command” cell also allows
the SET/RESET text, displayed in the hotkey menu, to be changed to something more
suitable for the application of an individual control input, such as “ON/OFF”, “IN/OUT” etc.
The “CTRL. I/P LABELS” column makes it possible to change the text associated with each
individual control input. This text will be displayed when a control input is accessed by the
hotkey menu, or it can be displayed in the PSL.
Note: With the exception of pulsed operation, the status of the control inputs
is stored in battery backed memory. In the event that the auxiliary
supply is interrupted the status of all the inputs will be recorded.
Following the restoration of the auxiliary supply the status of the
control inputs, prior to supply failure, will be reinstated. If the battery
is missing or flat the control inputs will set to logic 0 once the auxiliary
supply is restored.
