11.2.2 Diagnostic Interrupts
Internal errors, external errors and external channel errors are indicated to an
interrupt-capable system by means of diagnostic interrupts (see diagnostic
interrupt data in Table 11-4, ). This presupposes that the diagnostic interrupt
message was activated at the time of configuration (see Chapter 5.2). If the
system is not interrupt-capable, the diagnostic interrupt information must be
read out cyclically with FC 6.
The diagnostic interrupts are identified by setting the corresponding byte bit
number in the data set (see diagnostic interrupt data, Section 6.4) and com-
prise the signals for all three channels.
Error Class Coding Message
Internal errors Byte.bit no. 0.1
Group error byte 2, 3
“INF” LED
External errors Byte.bit no. 0.2 “EXTF” and “STAT” LED
External channel errors Byte.bit no. 0.2, 0.3 “EXTF” and “STAT” LED
Group error byte 8
The operator control errors in the “external channel error” class are specified
again, and are stored in data set 164/199/234 or in the diagnostic buffer.
The FM 453 signals a diagnostic interrupt “incoming” or “outgoing.”

If processing is to continue after a diagnostic interrupt, then Restart after the
error has been remedied in the appropriate channel (see write job no. 11 Sec-
tions 6.2.1 and 9.3.3).
Internal errors cannot be acknowledged. External errors are self-acknowledg-
ing.
