From LLP

The From LLP component receives data on a port using the LLP protocol. This is an upstream component and pushes the received data downstream.

Running the Component

Info

The below steps assume an the required network/firewall configurations have been made on the machine to allow incoming connections.

STEP 1: Import the From LLP component

Using +COMPONENT, import the From LLP component.

STEP 2: Set up the component configurations

Message Configurations:

Field	Description	Default Value
Message Encoding	The encoding used in the input data.	Use System Default ISO-8859-1 on Linux/MacOS or Windows-1252 on Windows
LLP Prefix	Prefix to use in LLP data. Should be in the form of an escaped hex value.	\x0B
LLP Suffix	Suffix to use in LLP data. Should be in the form of an escaped hex value.	\x1C\x0D

Connection Configurations:

Field	Description	Default Value
Port	The port number to listen for incoming connections.	65430
Enable Connection Timeout	Enable/disable timing out idle connections.	true
Timeout After	Length of time in minutes to close idle connections. (Only applicable if EnableConnectionTimeout = true)	30
SSL Certificate	Path to certificate file. If certificate and key files are provided, SSL will be enabled.
SSL Key	Path to private key file. If certificate and key files are provided, SSL will be enabled.
Verify Peer	Enable Verify Peerto verify the server sending you messages.	false

ACK Configurations:

Field	Description	Default Value
Ack Generation	Type of ACK generation to be used. Options: Fast, Custom	Fast

Debug Configurations:

Field	Description	Default Value
Print Debug Logs	Enable/disable logging of additional debug information.	false

STEP 3: Start the component and verify data is being received and ACKs are being sent

Start the component.

Send data to the port specified by the component. Verify that the data is being received correctly, and an ACK response is being sent to the client.

Adapting the Component

There are a few ways you can adapt and expand this component for more complex workflows:

Custom ACK generation

By default, the From LLP component uses fast ACK generation which creates a default ACK message based on data within the incoming HL7 message.

To implement custom ACK messages, modify the ACKcustomAck function with your logic to generate the desired ACK response:
