The following table lists the CIP API Library functions. Details of each function
follow in subsequent sections:
Function Category Function
Initialization OCXcip_Open - Starts the backplane engine and initializes access to the CIP
API.
OCXcip_OpenNB
- Allows access without opening backplane access.
OCXcip_Close - Terminates access to the CIP API.

Object, enabling other devices in the CIP system to establish connections with
the object. Callbacks are used to handle connection and service requests.
OCXcip_UnregisterAsssemblyObj
- Unregisters all instances of the
Assembly Object that had previously been registered. Subsequent connection
requests to the object are refused.
Callback Registration OCXcip_RegisterFatalFaultRtn - Registers a fatal fault handler routine.
OCXcip_RegisterResetReqRtn - Registers a reset request handler routine.
Connected Data Transfer OCXcip_WriteConnected - Writes data to a connection.
OCXcip_ReadConnected - Reads data from a connection.
OCXcip_WaitForRxData - Blocks until new data is received on connection.
OCXcip_ImmediateOutput - Transmit output data immediately.
OCXcip_WriteConnectedImmediate - Update and transmit output data
