Packet Communication
• The module establishes panel communication using the TCP/IP protocol.
• At start up, the module opens a TCP/IP connection that remains open indefinitely.
• The socket can be closed by the module or panel after a time‑out.
• The connection is re‑established by the module after the time‑out.
• A pair of supervision packets are sent every 5 seconds.
‑ The payload for each packet is 18 bytes and the total traffic, including
overhead, is approximately 2 kilobytes per minute for each 734N Series
module.
‑ Non‑Supervision messages have a payload range of 18‑50 bytes.
