4.4.2 Tab: I/O Submodule DO24_02
The I/O Submodule DO24 02 tab contains the following statuses and parameters:
Name R/W Description
Enter these statuses and parameters directly in the Hardware Editor.
Name W
Module name
Output Noise Blanking W Allow output noise blanking performed by the output module
(activated/deactivated).
Default setting: Deactivated (
recommended! )
If a discrepancy exists between the channel's default and
read-back values, the channel switch-off is suppressed.
SC/OC Interval [µs] W SC/OC interval of test impulse ( ≥ 40 ms)
Default setting: 40 000 = 40 ms
See Chapter 4.3
Show Open-Circuit W Display via LED
Field
(activated/deactivated)
Default setting: Activated
Show Short-Circuit W Display via LED
Field
(activated/deactivated)
Default setting: Activated
External Power Supply over W It specifies the type of external power supply:
ƒ Redundant
Redundant L1/L2
ƒ Mono on
Mono L1
ƒ Mono on
Mono L2
Default setting: Redundant L1/L2
Name Data type R/W Description
The following statuses and parameters can be assigned global variables and used in the user program.
Background Test
Error
BOOL R TRUE: Background test is faulty
FALSE: Background test is free of faults
Diagnostic
Request DINT W To request a diagnostic value, the appropriate ID must be sent
to the module using the parameter
Diagnostic Request
(see
Chapter 4.4.5 for coding details).
Diagnostic
Response DINT R As soon as
Diagnostic Response
returns the ID of
Diagnostic
Request
(see 4.4.5 for coding details),
Diagnostic Status
contains the diagnostic value requested.
Diagnostic Status DWORD R Requested diagnostic value in accordance with
Diagnostic
Response.
The IDs of
Diagnostic Request
and
Diagnostic Response
can
be evaluated in the user program.
Diagnostic Status
only
contains the requested diagnostic value when both Diagnostic
Request and Diagnostic Response have the same ID.
Restart on Error BOOL W
Using the parameter
Restart on Error
, each I/O module that
has switched off permanently due to faults can be forced to re-
adopt the RUN state. To do this, set the
Restart on Error
parameter FALSE to TRUE.
The I/O module performs a complete self-test and only enters
the RUN state if no faults are detected.
Default setting: FALSE
Submodule OK BOOL R TRUE: No submodule fault, no channel faults
FALSE: Submodule fault.
Channel fault (external faults included)
Submodule
Status
DWORD R Bit-coded submodule status (For coding details, see
Chapter 4.4.4)
