The definition of XCommands provides the possible linkage of logical functions between multiple different server items. The defined XCommands can be executed by defining events which react on input value of the involved server items.

Since version R2 Build 2071, there is second XCommand event definition file: <WorkspaceDirectory>\DataFiles\nxaXLogicEvents.VT.dat This file is automatically generated by the template engine of the visualization editor and loaded after the original definition file. |
This parameter defines the name of A name for the XCommand instance |
. The name must be uniqueThis parameter defines the scope where The scope in which the used internal variables of the XCommand are valid. All XCommand instances that are |
using configured for the same variable group |
are accessing access the same internal variables. This means that all XCommand instances |
are sharing share the same internal variables. If left empty, the instance name (column 1) is used as variable group. |
3 | Type |
This attribute defines when Specifies under which conditions and circumstances the XCommand shall be triggered. The following types are |
possible"" means that "TIMER" triggers cyclically (the interval in seconds can be specified in "Options" column)."" "_TIMER_ANDINPUT" is used for XCommands that shall be triggered cyclically and whenever one input item changes."ON_STOP" means that the XCommand is executed once when the NETx BMS Core Server stops."ON_" means that "" means that "" means "" means that "" means that *: the XCommand is only executed when one of the input items is below a limit. ON_TIMER: the XCommand is cyclically triggered. ON_TIMER_AND_INPUT*: the XCommand shall be triggered cyclically and whenever any of the input items changes.
Types that are marked with an * require XCommands with an input field that gets tracked. E.g. XCommand SCRIPT will not work with these types (on saving the definitions, an error message will be logged). |
4 | Options | Depending on the selected type, different options can be specified here: |
"""TIMER": time interval (in seconds)"": trigger "ON_VALUE_CHANGE": tolerance * Trigger on start (default is false). If true, the logic is also executed on server start-up. Synchronous call (default is false). If true, the logic is executed synchronous i.e. no other server tasks or events are triggered until the execution is finished.
|
"ON_TIMER_AND_INPUT": time interval (in seconds)."ON_STOP": no options.."in order to trigger the event. Trigger on start (default is false). If true, the logic is also executed on server start-up. Trigger on uncertain value: If true, the logic is also executed when a value changes from good quality to uncertain.
ON_VALUE_RISING
|
": tolerance . "'Once"' means that the command is only executed once in order to trigger the event. Once: if enabled, the XCommand is executed a single time after it begins to rise.
|
Trigger on start (default is false). If true, the logic is also executed on server start-up."": tolerance . "'Once"' means that the command is only executed once in order to trigger the event. Once: if enabled, the XCommand is executed a single time after it begins to fall.
|
"": "'limit"' which "'Once"' means that once In addition, a hysteresis can be specified too."": "'limit"' which underrun "'Once"' means that once is underrun. In addition, a hysteresis can be specified tooON_TIMER Timer type (cyclic or time). If cyclic is selected, the logic will be triggered in a cyclic interval. If time is chosen, the logic will be triggered every day at a given point in time. Interval: The interval in seconds. Time: The time at which the XCommand shall be executed every day.
ON_TIMER_AND_INPUT* Timer type (cyclic or time). If cyclic is selected, the logic will be triggered in a cyclic interval. If time is chosen, the logic will be triggered every day at a given point in time. Interval: The interval in seconds. Time: The time at which the XCommand shall be executed every day.
Types that are marked with an * require XCommands with an input field that gets tracked. E.g. XCommand SCRIPT will not work with these types (on saving the definitions, an error message will be logged). |
5 | XCommand | The |
parameter defines the XCommand that shall be executed. To assist in selecting the inputs, outputs, and parameters, a dialog is available which can be open via the "..." button. |
6 | Inputs |
This parameter defines the The inputs of the XCommand. If the XCommand is selected via the dialog, this parameter is filled automatically. |
7 | Outputs |
This parameter defines the The outputs of the XCommand. If the XCommand is selected via the dialog, this parameter is filled automatically. |
8 | Parameters |
This parameter defines the parameters Parameters of the XCommand. If the XCommand is selected via the dialog, this parameter is filled automatically. |
9 | Description | Optional description of the XCommand. The value is only used for documentation purposes. |
10 | Comment | Optional comment of the XCommand. The value is only used for documentation purposes. |
