OCXcip_ImmediateOutput

Syntax

int OCXcip_ImmediateOutput(OCXHANDLE apihandle,

OCXHANDLE connHandle );

Parameters

apiHandle

handle returned by previous call to OCXcip_Open

connHandle

handle of open connection

Description

This function causes the output data of an open connection to be queued for

transmission immediately, rather than waiting for the next scheduled

transmission (based on RPI). It is equivalent to the ControlLogix IOT instruction.

apiHandle must be a valid handle return from OCXcip_Open. connHandle must be

a handle passed by the connect_proc callback function.

Return Value

OCX_SUCCESS

data was read successfully

OCX_ERR_NOACCESS

apihandle does not have access

OCX_ERR_BADPARAM

connHandle or offset/dataSize is invalid

Example

OCXHANDLE apihandle;

OCXHANDLE connHandle;

BYTE buffer[128];

// Update the output data and transmit now

OCXcip_WriterConnected (apiHandle, connHandle, buffer, 0, 128);

OCXcip_ImmediateOutput (apiHandle, connHandle);
