6.5.6 Receiving Transparent Message Request (Server)
Because sending the response is not required when a transparent message is received by a server, only the MSG-RCV
function is started.
The following shows an example of transparent message reception according to non-procedure protocol.
ΠWhen it is necessary to send a response for a transparent message request, the MSG-SND function must be
started. For details, refer to 6.5.4 Sending Request (Client)/Response (Server) according to Non-procedure Protocol
on page 6-42.
( 1 ) MSG-RCV Function Setting
The MSG-RCV function is set as follows:
( 2 ) 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 Execute (DB000201) to ON (=1) causes a waiting state for message reception and then a
transaction code (10000) is stored in MW00000 and message data in the subsequent register (MW00001 and the subse-
quent) upon message reception.
ΠFor transaction codes, refer to 6.1.5 ( 5 ) PARAM05: Data Address on page 6-13.
