Hello!
Please help with the CIP protocol.
I am not a specialist in the industrial protocol Ethernet / IP. But I
want to gain experience in its use, for the competent use of the
OpENer library.
As a first experience, I decided to try to repeat the example from the
documentation on "A Guide for EtherNet / IP ™ Developers" (see Figure
3).
As the hardware, I have an Ethernet Field Coupler Wago 750-352 (see
Figure 1 and Figure 2).
From the program, I make requests to the Fieldbus coupler and get a
response, as shown in Fig. 4.
Transaction # 13 - Forward_Open request.
Transaction # 14 - Forward_Open response.
My question is about the response of Forward_Open. In response, in the
Type ID: Socket Address T2O field, it is equal to 192.168.1.51. How
can I change it?
Transaction No. 11 - I set the IP address of my computer 192.168.2.39
(scanner). (see fig. 5)
Please help me figure it out. What am I doing wrong.
The link contains all the specified images and the wireshark file.
