Diagnostic; Interrupt; Fig. 8-9: Protection Circuitry Of The Outputs (24 V) - Addi-Data APCI-2032 Technical Description

APCI-1032, APCI-1564 and APCI-2032

Diagnostic

2 diagnostic bits are available on the APCI-1564 and APCI-2032.
ϑ
The -diagnostic (only for the 24V version) is released:
when short-circuit has occurred on an output or
-
in case of overtemperature on an output component (8 channels).
-
The V -diagnostic informs that:
cc
the external voltage supply has dropped < 5 V (24 V version) or
-
< 3 V (5 V version).

Interrupt

The boards APCI-1564 and APCI-2032 have 2 interrupt sources.
Possible interrupt sources:
ϑ
-Diagnose
-
V -Diagnose
-
cc
Both diagnostic functions can generate an interrupt. The status of the diagnostic sources
is read through software.
