EEC = Emergency Error Code
ER = Error register
EEC (byte 0 and 1)
Byte 0 and 1 form a 16-bit error code.
Byte 2 to 5 are bit-field registers.
Byte 6 and 7 are fixed to 00h.
The 16-bit Emergency Error Code depends on the type of error. The table
below describes the three possible error codes.
EEC (hex) Description
0000 Error reset. At least one error has been resolved.
8100 Communication error
FF00 Device specific error
ER (byte 2) The error register (byte 2), has the same value as the object at index 1001
(see section 6-3).
The figure below shows the error register.
The error register indicates the type of actual error(s). It can either be a
device specific error or a communication error. Any type of error will also set
the generic error bit (bit 0 is always set when bit 4 or bit 7 is set).
