To LLP

The To LLP component sends messages to a port using the LLP protocol. It receives data from an upstream component.

Running the Component

The below steps assume an existing port is available to connect to and the necessary firewall permissions are in place on the client and server.

STEP 1: Import the To LLP component

Using +COMPONENT, import the To LLP component. Since it is a destination component, you will need to Edit Connections to link it to a source component that will push it data to send to the server port.

STEP 2: Set up the component configurations

Bolded fields are required, otherwise default values defined in config.json are used:

Connection Configurations:

Field

Description

Default Value

Host

The IP address or domain name of the target machine.

localhost

Port

The port number of the target machine.

65430

Persistent Connection

Whether or not to persistently connect to the remote host.

true

Connection Retry Count

Number of reconnect attempts if the connection is lost.

60

Retry Pause (s)

Length of pause between reconnect attempts in seconds.

10

ACK Configurations:

Field

Description

Default Value

Wait For Ack

Wait for an ACK before sending the next message. If false, all settings below are ignored.

true

Ack Timeout (s)

Number of seconds to wait for an ACK.

10

Disconnect Between Resends

Disconnect from the server between resend attempts.

true

Message Retry Count

Number of attempts to resend data until ACK is received.

5

Security Configurations:

Field

Description

Default Value

Enable SSL

Enable to receive messages securely using SSL.

false

Certificate Authority File (Optional)

Path to Certificate Authority File. If path is blank, Verify Peer will be disabled. If path is entered, Verify Peer will be enabled.

Message Configurations:

Field

Description

Default Value

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

Message Encoding

The encoding used in the input data. List of available encodings is available when you click to change the encoding.

Use system default ISO-8859-1 on Linux/MacOS or Windows-1252 on Windows

Component Configurations:

Field

Description

Default Value

Ack Error Handling

Error handling option if ACK is not received.

Options: Stop the component. Skip the message.

Stop the component

Print Debug Logs

Enable/disable logging of additional debug information.

false

STEP 3: Start the component and verify data is being received on target server

Start the component.

Once inbound data is processed, check that the target server is receiving the data as expected.

Adapting the Component

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

ACK Verification

By default, the To LLP component assumes that an ACK received from the target server is valid and verification is not needed. In some cases, additional ACK verification may be required.

Logic can be added to the ACKverify function to verify the ACK data. The function should return true/false based on the result of the verification.
