Hi Etienne, sorry for the late response ... couldn't read the image on my phone, but on the computer it's fine.
In your case the root element needs to be EipConnectionRequest and not EipRequest. I have to admit I too haven't completely grasped all the details of how Jackson parses and serializes stuff. But usually I paste an empty xml representation (in your case an empty EipPacket element) and put in the bytes. Then I run the test and obviously it fails complaining about what it parsed and that it looks different. I manually examine if the xml is correct and replace the empty element with the printed out verson.

As I never did such tests before, I don't know if the method is correct, but the results are similar to the ones I get running the same test for the s7. I also pushed this to my fork. Tomorrow I will try to do some tests on the PLC to see if I can perform fetching a lot of data (like I did on the s7) and if the writing works. > > Etienne > > On 2020/03/16 13:47:53, Christofer Dutz <[email protected]> wrote: > > Hi Etienne, > > > > You probably pulled in a SNAPSHOT from our maven repo ... if this is newer than yours, Maven usually pulls new versions the first time you build on every day. ... yes this can be annoying ;-) > > > > Chris > > > > Am 16.03.20, 14:41 schrieb "Etienne Robinet" <[email protected]>: > > > > Hi, > > Ok I see, seems to be resolved once rebuilt.

He calls the getLengthInBits on an implmentation of Message so that is where the error happens (also the @Override). I checked the Message interface and there is no such metho, also checked the pojo-template and couldn't find the method. I did not had that before when generating sources (I think since I ran some tests on the PLC). > > > Etienne > > > On 2020/03/16 12:46:48, Christofer Dutz <[email protected]> wrote: > > > > Hi Etienne, > > > > > > > > well the getLengthInBytes is still there ... it just calls the getLengthInBits and divides that by 8. > > > > The reason was that with the Firmata driver we first had a protocol where the getLengthInBytes returned 0 because one datatype didn't have a full multiple of 8 as content.

The reason I'm doing 1) in S7 and KNX is that I need to know the type from the request to decode in the S7 case and in the KNX case I need to know the type from an external source in order to decode it. > > > > > > > > > > > > > > > > > > > > > > > > > > > Chris > > > > > > > > > > > > > > > > > > Am 13.03.20, 14:45 schrieb "Etienne Robinet" <[email protected]>: > > > > > > > > > > > > > > > > > > Yes this is exactly what I need.

When sending a request for multiple elements (let's say 10 elements of an array), you get a response from the PLC with all the data at the end of the packet. The problem is, in the request there is the number of elements we want, but not in the response. So so the protocol knows how many elements there are in the response packet, but not the packet itself. This is quite a problem as for the parse, we need to know the length of the 'data' array containing the response data (for now it was only depending on the type, but I would need type*elements). > > > > > > > > > > > > > > > > > > > > > > I tested a bit by modifying the generated IO, and 1 way to do it is to get the remaining bytes and divide this by the datatype size. I just wanted to ask if someone would know how to declare this in the mspec, as I don't want to touch at the template. I also thought about having an attribute on the response, but I don't know how to put an attribute that won't get parsed/serialized.

I managed to make a quick test and read via the tag name. Now my question is: can I create sub-types that are also discriminated with sub-subtypes?

When the command of an EipPacket is '0x66' this means SendRRData (for Read/Write and Request/Response so I have to discriminate it on the sub level). The problem is that after generation, CipRRData implements Message but does not extend EipPacket. How should I do it?

The thing is, CIP is (from what I heard) proper to Allen Bradley. Should I leave it in the EIP driver or modify and adapt the current AB driver later on?
