13: T ROUBLESHOOTING
When a memory cartridge is installed on the CPU module, the user program in the memory cartridge is checked.
0010h: Timer/Counter Preset Value Sum Check Error
The execution data of timer/counter preset values is broken. The timer/counter preset values are initialized to the
values of the user program automatically. Note that changed preset values are cleared and that the original values are
restored. Clear the error code using the HMI module or WindLDR on a computer.
0020h: User Program RAM Sum Check Error
The data of the user program compile area in the Web server CPU module RAM is broken. When this error occurs, the
user program is recompiled automatically, and the timer/counter preset values and expansion data register preset
values are initialized to the values of the user program. Note that changed preset values are cleared and that the
original values are restored. Clear the error code using the HMI module or WindLDR on a computer.
0040h: Keep Data Sum Check Error
This error indicates that the data designated to be maintained during power failure is broken because of memory
backup failure. Note that the “keep” data of internal relays and shift registers are cleared. Data of counters and data
registers are also cleared. Clear the error code using the HMI module or WindLDR on a computer.
If this error occurs in a short period of power interruption after the battery has been charged as specified, the battery
is defective and the CPU module has to be replaced.
0080h: User Program Syntax Error
This error indicates that the user program has a syntax error. Correct the user program, and download the corrected
user program to the Web server CPU module. The error code is cleared when a correct user program is transferred.
0100h: User Program Writing Error
This error indicates a failure of writing into the Web server CPU module ROM when downloading a user program. The
error code is cleared when writing into the EEPROM is completed successfully. If this error occurs frequently, the Web
server CPU module has to be replaced.
When a memory cartridge is installed on the CPU module, writing into the memory cartridge is checked.
0200h: CPU Module Error
This error is issued when the ROM is not found. When this error occurred, turn power off and on. Clear the error code
using the HMI module or WindLDR on a computer. If this error occurs frequently, the Web server CPU module has to be
replaced.
0400h: Clock IC Error
This error indicates that the real time calendar/clock in the clock cartridge has lost clock backup data or has an error
caused by invalid clock data.
Clear the error code and set the calendar/clock data using the HMI module or WindLDR on a computer. The clock
cartridge will recover from the error. If the error continues, the clock cartridge has to be replaced. See
“Troubleshooting Diagram 11” on page 13-18.
1000h: Memory Cartridge Program Transfer Error
This error indicates that the user program cannot be downloaded to/uploaded from CPU module using the memory
cartridge. The memory cartridge program transfer fails when one of the following conditions is met:
• When the user program in the CPU module is password-protected and the password of the user program in the memory
cartridge does not match. Configure the correct password to the user program in the memory cartridge. For details on entering
the password, see "Programming WindLDR" of the basic volume (page 2-93).
• When uploading the user program from the CPU module is prohibited. Upload cannot be executed.
2000h: I/O Bus Initialize Error
This error indicates that an I/O module has a fault. If this error occurs frequently or normal I/O function is not restored
automatically, the I/O module has to be replaced.
