List of Error Codes for Micro800 controllers
Error Code Fault Type Description
(4)
0xFFzz Recoverable A user-created fault from Connected Components
Workbench has occurred.
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.
0xD011 Recoverable The program scan time exceeded the watchdog
timeout value.
(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.)

Recommended Action
See Corrective Actions for Recoverable Faults on page
See Corrective Actions for Recoverable Faults on page
Perform the following:
• See Corrective Actions for Recoverable Faults on page
• 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.
3. Put the Micro800 controller into Run mode.
If your program is designed to have a scan time of longer than three
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.
