10.8.3 Transmission behavior of the EMCY message
The EMCY message is only sent once, even if the warning and/or the error
is retained for an extended period. As long as no new warning and no new
error occurs, no further EMCY message is sent.
If a warning or error is removed, an EMCY message with EEC 0 (Error reset
or no error) is sent. The Error Register (ER) contains only the pending warn-
ings or errors, however.
If no warning and no error are present anymore, the error register is reset
to 0.
10.8.4 Properties of EMCY messages
A communications error (Overrun EEC 0x8110, Error state EEC 0x8120)
remains in the error register (object 1001h) (bit 0 and bit 4 set) until the
command “Communication Reset” or “Application Reset” was performed.
