CCPU_StartWDT
This function sets and starts the user WDT of a C Controller module.
■Format
short CCPU_StartWDT(short sType, short sInterval)
■Argument
Argument Name
sType WDT type
sInterval WDT interval
■Description
• The user WDT is the timer for detecting a hardware failure or program error.
• This function sets an interval of the WDT to the WDT interval (sInterval) 10 ms and starts the user WDT.
• If the user WDT is not reset periodically within the set time (by execution of the CCPU_ResetWDT function), a user WDT
error will occur. When a user WDT error occurs, a C Controller module will be in the stop error state. (The BUS RUN LED
turns OFF, and the ERROR LED starts flashing.)
• When this function is executed while the WDT is running, an error will be returned.
