ReadBool (FUN) ¶ FUNCTION ReadBool : DINT The ReadBool method reads one bit from the given offset into value. @param deviceId The device to read the bit from. @param bitOffset The bit offset to read the bit at. @param data Pointer to where the bit will be read to. @return Returns 0 on success, -1 otherwise. InOut: Scope Name Type Return ReadBool DINT Input deviceId DINT taskId UDINT bitOffset UDINT value POINTER TO BOOL

ReadBytes (FUN) ¶ FUNCTION ReadBytes : DINT Reads size bytes at offset from the devices pi into data. @param deviceId Id of the device @param offset Offset at which the data will be read. @param size Size of the data to read. @param data Pointer to the buffer. @return Returns 0 on success, -1 otherwise. InOut: Scope Name Type Return ReadBytes DINT Input deviceId DINT taskId UDINT offset UDINT size UDINT data POINTER TO BYTE

ReadEnd (FUN) ¶ FUNCTION ReadEnd : DINT Finishes the reading of process data. @param deviceId The id of the device. @param taskId The if of the task. @return Returns 0 on success, -1 otherwise. InOut: Scope Name Type Return ReadEnd DINT Input deviceId DINT taskId UDINT

ReadStart (FUN) ¶ FUNCTION ReadStart : DINT Starts the reading of the pi.Usually this is the point when the pi is read out from the device. @param deviceId The id of the device. @param taskId The id of the task. @return Returns 0 on success, -1 otherwise. InOut: Scope Name Type Return ReadStart DINT Input deviceId DINT taskId UDINT

RegisterEventHandler (FUN) ¶ FUNCTION RegisterEventHandler : DINT Actually not implemented InOut: Scope Name Type Return RegisterEventHandler DINT Input deviceId DINT handler tEventHandler userData POINTER TO BYTE

UnregisterEventHandler (FUN) ¶ FUNCTION UnregisterEventHandler : DINT Actually not implemented InOut: Scope Name Type Return UnregisterEventHandler DINT Input deviceId DINT handler tEventHandler

WatchdogSetTime (FUN) ¶ FUNCTION WatchdogSetTime : DINT Sets the watchdog time. The time until the watchdog triggers is the multiplication of factor and timeout_us. @param factor The factor specifies how often the timeout_us has to elapse until the watchdog triggers. @param timeout_us The timeout of the watchdog in microseconds. @return Return DAL_SUCCESS on success, DAL_FAILURE otherwise. InOut: Scope Name Type Return WatchdogSetTime DINT Input factor UDINT timeout_us UDINT

WatchdogStart (FUN) ¶ FUNCTION WatchdogStart : DINT Starts the watchdog. @return DAL_SUCCESS on InOut: Scope Name Type Return WatchdogStart DINT
