The control flag function setup and default settings must be predefined in the VS for the actual virtual indicator.
The setup menu is the standard analogue input adjust menu, presented in another section of this document.
More complex control of a flag may require digital input(s) on the DX1 module instead.
11.10.2 DX1 - Universal digital input of a control flag
Control flags may also be externally controlled using a digital input (DX1). The input can be defined to control a flag
in the object index table.
This can be used to control visibility of a data type as described for the AX1 module or other similar control
functions. Two digital inputs can also be set up as a pair to control 4 flag levels.
In XDi-N this function can for example be used to externally control the shift between several screens on the XDi or
even screen shift on a complete group of XDi-N indicators connected via CAN and using the screen mode group
function (see separate description).
The digital flag setup can set a defined object index to a predefined internal control flag value.
This function may be used in customised libraries, and the function depends on the actual indicator application.
Therefore, it is not described in more details in this manual.
11.11 DX1 Relay output adjust
The two relay outputs on the DX1 module can be configured to be controlled either by product-related event, pre-
set in the selected PP and/or by an indicator-specific event predefined in the VS profile for the selected virtual
indicator.
The product related relay functions are available when a DX1 module is mounted. If the function is disabled in the
PP, it can be activated from the installation menu.
The virtual indicator (VI)-related relay functions must be preconfigured in the VS profile for the relay function to be
available in the menu. If menu lines are greyed, out it is because they cannot be selected or edited.
It is possible to activate both PP and VI relay control at the same time. If both are active, the XDi performs
an “or”
function, and if one of the events is true, the relay will be activated. This means that the relay can be activated both
if the indicator pointer is within a critical band and if data is lost (warning).
To enter the Relay setup go to Install menu-> Adjust output-> Relay setup, and select the relay:
In this example, relay 1 is set up to be activated when a warning or caution event is present in the XDi. The actual
warning or caution that will activate the relay depends on which warnings or cautions are activated in the selected
PP or set up via the XDi user menu.
The grey functions in the menu will first be active if the “VI relay active” is activated. In this example, the VI-related
functions are not predefined in the VS, and
the “VI relay active” is therefore greyed out too.
