Using RSC services You have the option of using the already registered RSC services of the SDK via theServiceManager. TheServiceManager acts as the RSC API and is used to request services. Note: From firmware release 2022.0 LTS on, RSC services can also communicate via gRPC. Application RSC services are available for the… Read More
REST data interface – Variables Note: Phoenix Contact reserves the right to make changes and additions in further versions that might lead to incompatibilities. Therefore it is highly recommended to call this REST data interface out of your application explicitly with the version used during development, not with the latest key. Read Variable(s) This command… Read More
RSC PROFINET Services The PROFINET component can be extended via interfaces for PROFINET services. You can use one interface for acyclic communication (RecordRead, RecordWrite). The interface is available via the RSC protocol. The parameter data, diagnostic information, and status information (PDI = Parameters, Diagnostics and Information) of a PROFINET… Read More
Modbus TCP client Available from firmware 2024.6 Modbus is a long-living communication standard in industrial automation. It has been developed to communicate via TCP and meeting security needs. There are different Modbus implementations available, e.g. as a function block (available in the PLCnext Store). But using a… Read More
Querying notifications via RSC INotificationLoggerService Notifications that have been saved by means of the Notification Logger can be queried via RSC interfaces, and one that is already provided with the PLCnext Runtime System is thisINotificationLoggerService. With the release of the PLCnext Control RFC 4072R which is the first PLCnext Control device made for system redundancy, an additionalINotificationLoggerService2 is provided… Read More
Communication via MQTT broker Available from firmware 2024.0 LTS PLCnext devices running firmware 2024.0 LTS or newer can communicate not just to Proficloud but to any MQTT broker, e.g. those provided by Amazon Warehouse Services (AWS) or Microsoft Azure. This implementation of an MQTT client directly within the firmware is one of many possibilities,… Read More
RSC GDS services Note: The execution of RSC services can take some time. For this reason, avoid direct calls from ESM tasks that are scheduled for real-time execution. IDataAccessService During runtime, the function extensions can use the IDataAccessService interface to have read and write access to the GDS data. The… Read More
Using gRPC communication in PLCnext Technology Short introduction to gRPC gRPC is a modern open source high performance Remote Procedural Call (RPC) framework. Initially developed at Google and now lead by the Cloud Native Computing Foundation. It is very flexible and user-friendly, it can easily put in communication… Read More
RSC Axioline Services The Axioline component can be extended via interfaces for Axioline services. You can use one interface for acyclic communication (PdiRead, PdiWrite). This interface is available via the RSC protocol. The parameter data, diagnostic information, and status information (PDI = Parameters, Diagnostics and Information) of an… Read More
RSC (Remote Service Calls) Function extensions can communicate with the PLCnext Technology core components via the RSC interface. You can access various functions and data items via the interfaces. For example, you can gain read and write access to the Global Data Space (GDS) data using the IDataAccessService RSC service. … Read More
