0xF0Dz
(3)
Recoverable
When power was applied to the plug-in I/O module 
or the plug-in I/O module was removed, a hardware 
error occurred.
Perform the following:
1. See Corrective Actions for Recoverable Faults
 on page 313.
2. Correct the plug-in I/O module configuration in the user program.
3. Build and download the program using Connected Components Workbench 
software.
4. Put the Micro800 controller into Run mode. 
0xF0Ez
(3)
Recoverable
The plug-in I/O module configuration does not 
match the actual I/O configuration detected.
Perform the following:
1. See Corrective Actions for Recoverable Faults
 on page 313.
2. Correct the plug-in I/O module configuration in the user program.
3. Build and download the program using Connected Components Workbench 
software.
4. Put the Micro800 controller into Run mode. 
0xF830 Recoverable An error occurred in the EII configuration.
Perform the following:
• See Corrective Actions for Recoverable Faults
 on page 313.
• Review and change the EII configuration in the Micro800 controller properties.
0xF840 Recoverable An error occurred in the HSC configuration.
Perform the following:
• See Corrective Actions for Recoverable Faults
 on page 313.
• Review and change the EII configuration in the Micro800 controller properties.
0xF850 Recoverable An error occurred in the STI configuration.
Perform the following:
• See Corrective Actions for Recoverable Faults
 on page 313.
• Review and change the EII configuration in the Micro800 controller properties.
0xF860 Recoverable
A data overflow occurred.
A data overflow error is generated when the ladder, 
structured text, or function block diagram 
execution encounters a divide-by-zero.
Perform the following:
1. See Corrective Actions for Recoverable Faults
 on page 313.
2. Correct the program to ensure that there is no data overflow.
3. Build and download the program using Connected Components Workbench 
software.
4. Put the Micro800 controller into Run mode. 
0xF870 Recoverable An index address was out of data space.
Perform the following:
1. See Corrective Actions for Recoverable Faults
 on page 313.
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 313.
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 313.
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 313.
• 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 313.
• 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 313.
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.
