Error History Log File
Up to a maximum of 30 errors can be logged in chronological order inside the
Counter Unit, constituting the Error History Log File. If multiple errors are active at
the same time every error (-code) can be read sequentially into CIO (n+15, n+16)
by using the Read Next Error bit. Every next error is read from the Error History
Log File at the rising edge of the Read Next Error bit. If you attempt to read an
error after the last error in the list has been read, the value of zero will be returned.
Now you can scroll through the same error list again from the next rising edge of
the Read Next Error bit.

DM-configuration errors
DM-configuration errors are detected during initialisation after the Unit has been
powered up or restarted. DM-configuration errors can also be detected after the
IOWR-instruction “(Re) Configure Unit” has been issued (refer to section 4-5-3-4
“(Re) Configure Unit”
). In case a DM-configuration error is detected the Unit will
report the error and stop operating. The error(s) can be read in CIO using the “Read
Next Error” bit.

(The range of a valid BCD-code for a digit is
0-9. If one or more digits is within range A-F an invalid
BCD-code is specified).
