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

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

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.

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:
