6.5.5 Sending Request/Receiving Response (Client)
according to Non-procedure Protocol
As for FL-net messages other than transparent messages, the MSG-RCV function must be started to receive a response
message after message request was sent by the MSG-SND function.
The following shows an example of a profile read for response reception after request was sent. In this example, a pro-
file read transaction code (65011) is set in MW00000 and sent, a response code (65211) for the received profile is
stored in MW10000 and profile data is stored in MW10001 and subsequent.
