Error Register, Predefined Error Field

Error history
90
The EMCY trigger indicates which error has caused the emergency message
to be transmitted. The reason can be that an new error has occurred (EEC ≠
0) or that an error has been resolved (EEC = 0).
Note When the last error has been resolved, the emergency message will contain
8 zero's!
The following figure shows the bit definitions of the EMCY trigger.

The C200HW-CORT21-V1 has two object entries in the object dictionary that
indicate the actual and previous errors since the last time the Unit was reset.
Error Register – Object entry 1001h
The error register is a simple 8-bit variable that stores the actual errors. This
byte is also transmitted as part of the emergency message and a description
of this byte can be found in the section that describes the emergency
message (section 6-2)
Predefined Error Field – Object entry 1003h
The Predefined Error Field is an array of 32-bit variables. The figure below
shows the structure of this object entry.
