6.5.4 Sending Request (Client)/Response (Server)
according to Non-procedure Protocol
As for transparent messages, only the MSG-SND function is started because no response reception processing is
required after request was sent.
Though the server usually sends no response at transparent message request reception, it starts only the MSG-SND
function independently to send a response if necessary.
The following shows an example for sending transparent message with the data size of 512 words in MW00100 and
the subsequent to a destination with node number 1.
( 1 ) MSG-SND Function Setting
The MSG-SND function is set as follows:
( 2 ) MSG-SND Parameter Setting
The parameter list from DA00000 is set as follows:
ΠFor register access method and notes at register input, refer to 6.4 Displaying a Register List and Notes at Register
Input on page 6-30.
In the above setting, setting a request transaction code of the transparent message (10000) in MW00100 and message
data in the subsequent register (MW00001 and subsequent), and then setting Execute (DB000201) to ON (=1) starts the
MSG-SND function so that the 262IF-01 can send the transaction code and message data from MW00100.
ΠFor transaction codes, refer to 6.1.5 ( 5 ) PARAM05: Data Address on page 6-13.
