Requires: FPGA Module

Use the Tag channel to share a single value among multiple readers and/or writers. Sharing the value is similar to sharing a global or network shared variable. Each time a writer endpoint writes a value to the channel, the value overwrites the existing value in the channel to ensure that the reader endpoints always read the latest value.

Refer to the Channel Wire Endpoints Details topic for information about Timed Loop compatibility, usage, and resource considerations related to the Tag endpoints.

Endpoint Description
Read Reads a value from a Tag channel.
Read With Abort Reads a value from a Tag channel or signals the channel to abort. This endpoint is the same as the Read endpoint except that it has an abort input and an aborted? output. You can use the abort capability of the Tag channel to close a channel abruptly, ignoring any data left in the channel buffer. You must use this endpoint together with the Write With Abort endpoint.
Write Writes a value to a Tag channel.
Write With Abort Writes a value to a Tag channel or signals the channel to abort. This endpoint is the same as the Write endpoint except that it has an abort input and an aborted? output. You can use the abort capability of the Tag channel to close a channel abruptly, ignoring any data left in the channel buffer. You must use this endpoint together with the Read With Abort endpoint.
