The I/O Submodule DI64_01 tab contains the following system parameters: 
Name  R/W  Description 
This parameter cannot be changed. 
Name W Module name 
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 Re-
quest (see Chapter 
4.3.5 for coding details). 
Diagnostic Response  DINT  R 
As soon as Diagnostic Response returns the ID of Diag-
nostic Request (see 
4.3.5 for coding details), Diagnostic 
Status contains the diagnostic value requested. 
Diagnostic Status  DWORD  R 
Requested diagnostic value in accordance with Diagnos-
tic 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 Re-
start 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 (see  4.3.4 for coding details) 
Supply 1 OK  BOOL  R  The supplies are monitored for undervoltage 
TRUE: The supply is faultless. 
FALSE: The supply is faulty. 
Supply 2 OK  BOOL  R  Such as Supply 1 OK 
Supply 3 OK  BOOL  R  Such as Supply 1 OK 
Supply 4 OK  BOOL  R  Such as Supply 1 OK 
Supply 5 OK  BOOL  R  Such as Supply 1 OK 
Supply 6 OK  BOOL  R  Such as Supply 1 OK
