EipStatus EstablishIoConnection	(	CipConnectionObject *RESTRICT const	connection_object,
		EipUint16 *const	extended_error
	)

Setup all data in order to establish an IO connection.

This function can be called after all data has been parsed from the forward open request

Parameters

connection_object	pointer to the connection object structure holding the parsed data from the forward open request
extended_error	the extended error code in case an error happened

Returns

general status on the establishment

EIP_OK ... on success
On an error the general status code to be put into the response

Setup all data in order to establish an IO connection.

This function needs the guarantee that no Null request will be passed to it. It will generate a new IO connection based on the data parsed in the Forward Open service

Parameters

connection_object	pointer to the connection object structure holding the parsed data from the forward open request
extended_error	the extended error code in case an error happened

Returns

general status on the establishment
