Error History Log File
Up to a maximum of 30 errors can be logged in chronological order inside the
High-speed 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+17, n+18) 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 ris-
ing 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 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.

Offset (BCD)
Out of Range
The DM-setting located at
(Nx100) +
Offset
is Out of Range (N = Machine Number).
0310
Offset (BCD)
Invalid BCD-code
The DM-setting located at
(Nx100) +
Offset
is an invalid BCD-code (N = Machine
Number).
(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).

is outside the counting range that
is set for that Counter (N = Machine Number).
