Appendix C—Optional Communication Cards
Extended diagnostics frame has 10 bytes where first 4 bytes
are header followed by 6 bytes fault and warning data. For
example in above picture 0A 81 01 00 bytes are header
information. 1A 00 00 00 00 00 are diagnostics information
where 1A 00 forms a fault code word 0x001A, which means
Communication lost with MM. 00 00 00 00 are the warning
bits per Modbus register 318. When there is no fault or
warning in the system, all 6 bytes of diagnostics data will
be 0.
