JPIN values
Why am I getting this error? According to the documentation, the value of a JPIN is a real number, so why can I use some rational operators (= , <>), but not others (<, >, <=, >=)?
Answer
An update to this: I am getting 'False' values for the JPINs that are 2 bits in length. The other JPINs have the values I expect. Does anyone know why I would not be getting a value from 0 to 3? Is this a bug?
Answer
Not a bug - j1939 standard uses 2 bits for on/off with error checking. You can turn the j1939 error checking off in the JPIN and it will give you the 1-3 value.
