4.3.2 Tab: I/O Submodule DO12_01
The I/O Submodule DO12_01 tab contains the following statuses and parameters:
Name R/W Description
Enter these statuses and parameters directly in the Hardware Editor.
Name R 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.
Test Current Measuring W Functional check of the current measurement
(activated/deactivated)
Default setting: Deactivated
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 4.3.5 for coding details).
Diagnostic
Response DINT R As soon as Diagnostic Response returns the ID of Diagnostic
Request (see Chapter 4.3.5 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 4.3.4)
