Data receiving
Data is received by Consumer from Producer.
Data is received according to the following procedure.
1.
Connection establishment ((1) to (3) shown above)
The connection is established when 'EtherNet/IP communication start request' (Y10) of the RJ71EIP91 on the Producer side
and the RJ71EIP91 on the Consumer side is turned on, a connection open request is sent from the RJ71EIP91 on the
Consumer side to the RJ71EIP91 on the Producer side, and then the response is received by the RJ71EIP91 on the
Consumer side.
2.
Receiving data ((4) to (6) shown above)
If the connection is established normally, Consumer stores the received data in 'Class1 Input Area' (Un\G65536 to
Un\G98303).
For the operation timing of EtherNet/IP communications, refer to the following.
Page 137 EtherNet/IP communication start request (Y10)
(1) Turn on 'EtherNet/IP communication start request' (Y10).
(2) Connection open
(3) Response (normal)
(4) Send the stored data at the RPI interval.
(5) Receiving data
(6) Store the data received at the RPI interval.
