7 OPC UA ObjectTypes

7.6 IOLinkPortType ObjectType Definition

7.6.4 Methods of MethodSet

In Table 43, the Methods of the ObjectType, referenced via the MethodSet Object are defined.

Table 43 – MethodSet of IOLinkPortType

References	Node Class	BrowseName	Modelling Rule
The following Methods are also referenced by the Statistics Object
HasComponent	Method	ResetStatistics	Optional
The following Methods are also referenced by the Configuration Object
HasComponent	Method	UpdateConfiguration	Mandatory

7.6.4.1 ResetStatistics

The optional Method ResetStatistics resets all statistic data of the ports. Statistic data of a port are Parameters referenced by the Statistics Object of the IOLinkPortType Object starting with “NumberOf” and potentially vendor-specific extensions. As soon as statistic data is provided by the server, the optional Method shall be provided.

Signature

ResetStatistics (
[out]	Int32			Status
);

Argument	Description
Status	Returns the status of the operation.    0: OK, operation successful -1: Operation already running -2: Operation cannot be executed.

7.6.4.2 UpdateConfiguration

The Method UpdateConfiguration takes all configuration data as input and updates the configuration of the port. The Method execution ensures that a client provides all configuration data at the same time in a consistent way and thus the server can deploy the configuration in one operation. If the configuration is not valid, the server returns a corresponding Status. As defined in the SMI (see IO-Link Addendum) depending on the configuration some arguments are treated as “don’t care”. For example, when the PortMode is IOL_AUTOSTART, the DeviceID, VendorID and ValidationAndBackup are ignored. The server shall not check those arguments and accept configurations with all possible values.

Signature

UpdateConfiguration (
(
[in]	Duration		CycleTime,
[in]	Byte			ValidationAndBackup,
[in]	Byte			PortMode,
[in]	Byte			Pin2Configuration,
[in]	Boolean		UseIODD,
[in]	UInt32		DeviceID,
[in]	UInt16		VendorID,
[out]	Int32			Status
);

Argument	Description
CycleTime	Maps to CycleTime Variable defined in Table 38.
ValidationAndBackup	Maps to ValidationAndBackup Variable defined in Table 38. Only the numeric values defined for the Variable are allowed.
PortMode	Maps to PortMode Variable defined in Table 38. Only the numeric values defined for the Variable are allowed.
Pin2Configuration	Maps to Pin2Configuration Variable defined in Table 38. Only the numeric values defined for the Variable are allowed.
UseIODD	Maps to UseIODD Variable defined in Table 38.
DeviceID	Maps to DeviceID Variable defined in Table 38.
VendorID	Maps to VendorID Variable defined in Table 38.
Status	Returns the status of the operation.    0: OK, operation successful -1: Operation already running -2: Operation cannot be executed -3: Invalid configuration
