Detailed Description

This service provides operations to read status information from the device.

The service is defined in the library Arp.Device.Interface.
A current documentation of available device status information can be found in the Phoenix Contact "PLCnext Info Center", e.g.: PLCnext Info Center: IDeviceStatusService.

Realtime Usage: This API call does not have to be deterministic in runtime behaviour, so an asynchronous execution should be considered.

Member Function Documentation

virtual RscVariant< 512 > Arp::Device::Interface::Services::IDeviceStatusService::GetItem ( const RscString< 512 > & identifier )

pure virtual

This operation reads a single status information item.

Parameters

identifier String to select the respective status information item.

Returns: The result of the read operation as
RscVariant

Arp::System::Rsc::Services::RscVariant
Rsc container class for primitive data type, strings or information about arrays or structs....
Definition: RscVariant.hxx:69

on success,
RscType::Void

on error.

virtual void Arp::Device::Interface::Services::IDeviceStatusService::GetItems	(	GetItemsIdentifiersDelegate	identifiersDelegate,
		GetItemsResultDelegate	resultDelegate
	)

pure virtual

This operation reads a list of status information items.

Parameters

identifiers Arry of String select the respective status information items.

Returns: The result of the read operation as an array of
RscVariant

on success,
RscType::Void

on error.
