* |-----------------|---------|---------|-------------|
* | Port | uint16 | 44500 | TCP control port (multicast) or UDP server port (unicast). Values ≤ 1024 produce a warning. |
* | MulticastGroup | string | *(absent)* | **Enables multicast mode.** IPv4 multicast address, e.g. `"239.0.0.1"`. Must be in 224.0.0.0/4. Absent or empty = unicast. |
* | DataPort | uint16 | Port+1 | UDP port for multicast DATA datagrams. Ignored in unicast mode. Must be non-zero and differ from Port. |
* | MaxPayloadSize | uint32 | 1400 | Maximum bytes of signal payload per UDP datagram (excluding the 17-byte header). Larger signals are fragmented. |
* | PublishingMode | string | Strict | `Strict`: send one packet every Synchronise() call. `Auto`: rate-limited; flush only when MinRefreshRate interval has elapsed. |
* | MinRefreshRate | float64 | — | Required when PublishingMode = Auto. Flush frequency in Hz (e.g. 120.0). |
* | MaxBatchSize | uint32 | 1 | Optional when PublishingMode = Auto. Number of RT cycles to accumulate before flushing one packet. Scalar signals are expanded to arrays of MaxBatchSize elements; the first scalar with Unit="us" or "ns" is auto-promoted as the per-sample FullArray timestamp reference for all other scalars. When omitted or 1, the most-recent single value is sent at MinRefreshRate. |
