0xF870 Recoverable An index address was out of data space.
Perform the following:
1. See Corrective Actions for Recoverable Faults
on page 270.
2. Correct the program to ensure that there is no index used to access an array element
beyond the array boundaries.
3. Build and download the program using Connected Components Workbench software.
4. Put the Micro800 controller into Run mode.
0xF0878 Recoverable
An index used to access a bit is beyond the
boundaries of the data type it is used on.
Perform the following:
1. See Corrective Actions for Recoverable Faults
on page 270.
2. Correct the program to ensure that there is no index used to access a bit beyond the
boundaries of the data type.
3. Build and download the program using Connected Components Workbench software.
4. Put the Micro800 controller into Run mode.
0xF880 Recoverable A data conversion error occurred.
Perform the following:
1. See Corrective Actions for Recoverable Faults
on page 270.
2. Correct the program to ensure that there is no data conversion error.
3. Build and download the program using Connected Components Workbench software.
4. Put the Micro800 controller into Run mode.
0xF888 Recoverable
The call stack of the controller cannot support the
sequence of calls to function blocks in the current
project. Too many blocks are within another block.
Perform the following:
• See Corrective Actions for Recoverable Faults on page 270.
• Change the project to reduce the quantity of blocks being called within a block.
0xF898 Recoverable
An error occurred in the user interrupt configuration
for the plug-in I/O module.
Perform the following:
• See Corrective Actions for Recoverable Faults on page 270.
• Correct the user interrupt configuration for plug-in I/O module in the user program to
match that of the actual hardware configuration.
0xF8A0 Recoverable The TOW parameters are invalid.
Perform the following:
1. See Corrective Actions for Recoverable Faults on page 270.
2. Correct the program to ensure that there are no invalid parameters.
3. Build and download the program using Connected Components Workbench software.
4. Put the Micro800 controller into Run mode.
0xF8A1 Recoverable The DOY parameters are invalid.
Perform the following:
1. See Corrective Actions for Recoverable Faults
on page 270.
2. Correct the program to ensure that there are no invalid parameters.
3. Build and download the program using Connected Components Workbench software.
4. Put the Micro800 controller into Run mode.

Recoverable
A user-created fault from the Connected
Components Workbench software has occurred.
See Corrective Actions for Recoverable Faults on page 270.
0xD00F Recoverable
A particular hardware type (for example, embedded
I/O) was selected in the user program configuration,
but did not match the actual hardware base.
See Corrective Actions for Recoverable Faults on page 270.
0xD011 Recoverable
The program scan time exceeded the watchdog
timeout value.
Perform the following:
• See Corrective Actions for Recoverable Faults
on page 270.
• Determine if the program is caught in a loop and correct the problem.
Fault may occur if your Structured Text program contains a For loop with the upper limit
set to the maximum value of the variable. For example, the variable is a USINT and the
limit is set to 255, or the variable is a UINT and the limit is set to 65535.
To correct the fault, perform the following:
1. Correct the program to ensure that the upper limit is not reached. One method is to
use a data type with a larger maximum value.
2. Build and download the program using Connected Components Workbench software.
3. Put the Micro800 controller into Run mode.
If your program is designed to have a scan time of longer than 3 seconds, in the user
program, increase the watchdog timeout value that is set in the system variable
_SYSVA_TCYWDG and then build and download the program using Connected
Components Workbench software.
(1) z indicates the logic axis ID. (0...3)
(2) z indicates the slot number of the expansion I/O. If z=0, then the slot number cannot be identified.
(3) z is the slot number of the plug-in module. If z = 0, then the slot number cannot be identified.
(4) zz indicates the last byte of the program number. Only program numbers up to 0xFF can be displayed. For program numbers 01x00 to 0xFFFF, only the last byte is displayed.)
