ROUBLESHOOTING
Introduction
This chapter describes the procedures to determine the cause of trouble and actions to be taken when any trouble occurs
while operating the MicroSmart.
The MicroSmart has self-diagnostic functions to prevent the spread of troubles if any trouble should occur. In case of any
trouble, follow the troubleshooting procedures to determine the cause and to correct the error.
Errors are checked in various stages. While editing a user program on WindLDR, incorrect devices and other data are
rejected. User program syntax errors are found during compilation on WindLDR. When an incorrect program is down-
loaded to the MicroSmart, user program syntax errors are still checked. Errors are also checked at starting and during
operation of the MicroSmart. When an error occurs, the error is reported by turning on the ERR LED on the MicroSmart
and an error message can be viewed on WindLDR. Error codes can also be read on the HMI module.
