Read or write tag data to and from a configured SystemLink Server.
SystemLink Tags: Path to the SystemLink tag. If the tag does not already exist, it will be create during initialization.
Direction: Select whether the tag is being written to or read from the SystemLink Server.
Data Type: The data type of the configured channel. SystemLink directly supports only a subset of all DCAF data types so the selected data type will correspond to data types within the SystemLink server as follows.
| Selected Data Type | SystemLink Data Type |
|---|---|
| Double, Single | Double |
| U64, U32, U16, U8 | U64 |
| I32, I16, I8 | I32 |
| Boolean | Boolean |
| String | String |
| Timestamp | Timestamp |
Note: All tags will be stored in the Tag Bus as the selected data type except for
Timestampwhich is stored in the Tag Bus as a double.
Tag: The DCAF tag which the SystemLink channel will be mapped to.
Connection Type:
- HTTP - Enables you to specify the server URL, username, and password to initiate a connection with a SystemLink server through your authenticated credentials.
- API Key (SystemLink Cloud) - Enables you to specify the server URL and an API key to initiate connection to the SystemLink Cloud server.
- AMQP - Enables you to specify the Configuration ID of the server to initiate a connection to the server over AMQP.
Verify Server?: Specifies whether to verify the server's identity and establish a secure connection. The default is TRUE.
Server URL: The URL of the server hosting the SystemLink tags. The Server URL should use the format scheme://host:port. If not specified, the default scheme is http and the default port is 80.
CA Certificate File: The path to a list of trusted certificate authority (CA) certificates. If Verify Server? is TRUE, the client verifies the server's identity against this list of trusted certificates.
Username: The log-in username for the server configured
Password: The password associated with the configured username.
API Key: A string key which authenticates the client for SystemLink Cloud. API Keys can be generated by navigating to systemlinkcloud.com/security and clicking + New API Key.
Configuration ID: If left blank, the machine will first attempt to establish communication to the server specified in the SystemLink Client GUI. If the machine is not configured to connect to a SystemLink server, or if the server is unreachable, the client will attempt to connect to the local server.
For more information on specifying a configuration ID, review he document located at <ProgramData>\National Instruments\Skyline\SkylineConfigurations\readme.txt.
