Parameter

Name	Type	Description
nOID	OTCID	ObjectID of the TcIotOcppServer object. If this value is left at 0 (default), a new instance is created.
nTaskOID	OTCID	ObjectID of the task used. If this value is left at 0 (default), the I/O Idle Task is used.
sHost	T_MaxString	Defines the server address as a host name, domain name or IP address.
nPort	UINT	Defines the server port.
sPath	T_MaxString	Defines the server path.
eAuthMode	E_OCPP1_AuthenticationMode	Optional Authentication Mode.
eEncryptionMode	E_OCPP_EncryptionMode	Optional Encryption Mode.
eEncryptionProt	E_OCPP_EncryptionProtocol	Defines the Encryption Protocol.
sCaFile	T_MaxString	Certificate of the Certificate Authority (CA) as a file path (PEM or DER format).
sCrtFile	T_MaxString	Server certificate (Public Key) as file path (PEM or DER format).
sKeyFile	T_MaxString	Private Key of the server as a file path (PEM or DER format).
eDebugLevel	E_OCPP_DebugLevel	The Debug Level (None or MessageLogFile). MessageLogFile ensures that a logfile with all OCPP messages is written to the TwinCAT boot directory.
eTraceLevel	TcTraceLevel	The maximum Trace Level from ADS logging.
