(1) Turn on 'EtherNet/IP communication start request' (Y10).
(2) Connection open
(3) Response (normal)
(4) Receiving data
(5) Store the data received at the RPI interval.
(6) Transfer the stored data with a program.
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) on the RJ71EIP91 on the scanner side is
turned on, the connection open request is sent, and then a response is received from the EtherNet/IP device on the adapter
side.
2.
Receiving data ((4) to (5) shown above)
If the connection is established normally, the originator 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.
