Chris, all,
What is the recommended way to define the spec in the
plc4x/protocols/eip/src/main/resources/protocols/eip/eip.mspec
The current definitions for
PathSegment/LogicalSegment/InstanceSegment/InstanceId are defined for 8-bit
values (see below). We have live traffic for a 0x52 CipConnectedRead request
that contains 16-bit values for both the path segment and the instance ID, e.g.
0x25002000 w the instance being LE. There are class segment and a member
segment are both 8-bit. the format 2 bit value is 1 for the instance.
We can overload the LogicalSegment with a LogicalSegment16, but as the format
value is currently read down in the instance segment, i wasn't sure how to
approach it. It is straightforward to edit the generated java to read ahead
but that doesn't fit the mspec way (afaik).
This is part of a MultiServiceRequest where Service #1 includes an 8-bit
instanceId and Services #12 
 include the 16-bit.
I can see how the decriminator fields but wasn't sure how to define the look
ahead so that is generated properly.
Any thoughts?
Thanks!
Bob
