Conceptual Diagram of Transmission Buffer Channels
The following is a conceptual diagram of the transmission buffer channels.
ΠEven if different transmission buffer channels are used, it is not possible to start the MSG-SND functions
simultaneously for one device (IP address). If this is attempted, an error occurs when the MSG-SND function
is executed.

The MSG-SND functions use the 263IF-01 transmission
buffer channels to perform message communication.
A transmission buffer channel can start only one
MSG-SND function. In other words, one transmission
buffer channel cannot be used to start several
MSG-SND functions simultaneously.
