User Datagram Protocol (UDP) I/O Sequence Number Handshaking
The data producing device increments the data sequence number by one with the
transmission of each new serial data packet. Valid sequence numbers are 1-65535. After the
consuming device has processed the data, it must echo the sequence number in the
handshake to allow the producing device to remove the data from the queue. This is required
for I/O communications because UDP is not guaranteed to arrive in order.
If the Node ID number is passed as part of the I/O message, the message is stored to the
appropriate location in the Modbus RTU table. Because communications are asynchronous,
the Node ID number is also stored as part of the output data. It is the responsibility of the
PLC programmer to make sure the proper request lines up with the proper response if the
BIS M-626 is used as a request/response device.
