6.2 Message Receive Function
When a request is received assuming that the 262IF-01 is an FL-net message transmission server or a response is
received as a client, the message receive function MSG-RCV is used.
Upon FL-net message reception by the MSG-RCV function, the 262IF-01 automatically sends a response message and
quits the message function. When the MSG-RCV function has not been started, the received FL-net message is retained
in the 262IF-01 for 5 seconds, but is discarded unless the MSG-RCV function is started after 5 seconds passes.
As for FL-net messages to be looped back within the 262IF-01, the MSG-RCV function does not need to be started.
6.2.1 Basic Specifications
