sInterval WDT interval
Description
• The user WDT is the timer for detecting a hardware failure or program error.
• Sets an interval of the WDT of the VxWorks part to the WDT interval (sInterval) ×10 ms and starts the user WDT.
• If the user WDT is not reset periodically (by execution of the CCPU_ResetWDT function) within the time set for the WDT
interval (sInterval), a user WDT error will occur. When a user WDT error occurs, the MELIPC enters a stop error state. (The
MAIN ERR LED flashes.)
• When this function is executed while the user WDT is running, an error is returned.
