Emergency messages
When parametrized, the device sends emergency messages to the master
in case of detected diagnosis. The coding of the first and the second part of
the emergency messages are leaned to the CiA 301 and CiA 401
specifications. The third part of the emergency message is the known
(manufacturer defined) diagnostic register.
The emergency message has a format of 8 bytes and is coded as follows:
Content of the error register (CoE register 0x1001):
Content of the diagnostic register (depends on module 16DI, 16DO or
8DI/8DO):
Byte 1
Byte 2
Byte 3
