an application be designed as variable-length data. In Revision C, the case of the error detection is less than or equal 32
and Parameter length is 34.
*2 Value corresponding to the error message is transmitted (refer to Table 36 and Table 37). The most recent error has the
largest parameter number. When the number of errors being detected is under the maximum number, the value of
parameter that is larger than the number of errors being detected is set to 0.
