TCPEvent
Description
With this Action we can add one or more event handlers that can be received by the TCP socket.
Properties
Specific
-
Socket
EXPRESSION (object:TCPSocket)
-
The socket object on which we want to listen to events.
-
Event handlers
Array
-
List of events to be handled. For each item in the list, it will be necessary to select
Event,Handler typeand optionallyAction.Eventis the type of event we want to handle and the possible values are:Ready– Emitted when a socket is ready to be used.Data– Emitted when data is received.Close– Emitted once the socket is fully closed.End– Emitted when the other end of the socket signals the end of transmission, thus ending the readable side of the socket.Error– Emitted when an error occurs. The ‘close’ event will be called directly following this event.Timeout– Emitted if the socket times out from inactivity. This is only to notify that the socket has been idle. The user must manually disconnect the connection.
Handler typecan beFloworAction. IfFlowis selected then an output will be added through which the Flow execution continues if the event is sent. IfActionis selected, thenActionmust also be set, i.e. the name of the User action that is executed when the event is received.
General

Description
String
-
This is the description of the Action component. Description is displayed below the component in the Project editor/viewer. In the main toolbar, it is possible to hide or display descriptions of all components with one click.
Flow
-
Inputs
Array
-
Additional component inputs that the user can add as desired in order to use them to receive additional data needed when evaluating expressions in properties. Each input is given a name and type. Name is used when referencing an input within an expression. A type is used to project Check to check whether a data line that transmits data of that type is connected to the input or not.
-
Outputs
Array
-
Additional component outputs that the user can add to send data through. Each output is assigned a name and type. An example of using this output is e.g. in the Loop component, where we can put the output name for the
Variableproperty instead of e.g. variable name. In that case, the Loop component will not change the content of the variable in each step, but will send the current value through that output. -
Catch error
Boolean
-
If this checkbox is enabled then an
@Erroroutput will be added to the component and if an error occurs in this component during the execution of the Flow, the Flow will continue through that output. The data that will be passed through that output is the textual description of the error.
Position and size
-
Align and distribute
Any
-
Alignment icons and component distribution. Alignment icons appear when two or more components are selected, and distribution icons appear when three or more components are selected.
Inputs
-
seqin
SEQ | OPTIONAL
-
A standard sequence input.
Outputs
-
seqout
SEQ | OPTIONAL
-
A standard sequence output.
