Troubleshooting Appendix B
0xF301 The memory module’s project is not compatible with the
controller.
Perform one of the following:
• Check to make sure there is a user program with a controller that has the
correct controller catalog configured.
• Download a user program and use the backup function to the memory
module.
0xF302 The password is mismatched. Perform one of the following:
• Check to make sure that the user program in the memory module has the
correct password.
• Download a user program with a password and use the backup function
to the memory module.
• Use Connected Components Workbench to enter the correct password
into the controller and perform the restore operation again.
0xF303 The memory module is not present. Check to make sure the memory module is present.
For the following four error codes, z is the slot number of the plug-in module. If z = 0, then the slot number cannot be identified
0xF0Az The plug-in I/O module experienced an error during
operation.
Perform one of the following:
• Check the condition and operation of the plug-in I/O module.
• Cycle power to the Micro800 controller.
If the error persists, see the Micro800 Plug-in Modules User Manual,
publication 2080-UM004
.
0xF0Bz The plug-in I/O module configuration does not match the
actual I/O configuration detected.
Perform one of the following:
• Correct the plug-in I/O module configuration in the user program to match
that of the actual hardware configuration.
• Check the condition and operation of the plug-in I/O module.
• Cycle power to the Micro800 controller.
• Replace the plug-in I/O module.
If the error persists, see the Micro800 Plug-in Modules User Manual,
publication 2080-UM004
.
0xF0Dz 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. Correct the plug-in I/O module configuration in the user program.
2. Build and download the program using Connected Components
Workbench.
3. Put the Micro800 controller into Run mode.
0xF0Ez The plug-in I/O module configuration does not match the
actual I/O configuration detected.
Perform the following:
1. Correct the plug-in I/O module configuration in the user program.
2. Build and download the program using Connected Components
Workbench.
3. Put the Micro800 controller into Run mode.
0xD011 The program scan time exceeded the watchdog timeout
value.
Perform one of the following:
• Determine if the program is caught in a loop and correct the problem.
• 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.
0xF850 An error occurred in the STI configuration. Review and change the STI configuration in the Micro800 controller
properties.
0xF860 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. Correct the program to ensure that there is no data overflow.
2. Build and download the program using Connected Components
Workbench.
3. Put the Micro800 controller into Run mode.
