oneM2M TS-0040Release Notes diff from v5.0.3 to v5.0.2The architecture model followed in the present document is based on the architecture model in oneM2M TS0001 [1] that describes how interworking between oneM2M CSEs and non-oneM2M systems using specialized Interworking Proxy application Entities (IPEs). The present document describes the Modbus IPE that supports the following reference model.


Figure 5.1‑1: Modbus interworking reference model
As shown in Figure 5.2‑1, the Modbus IPE consists of AE and Modbus Master [i.2]. To provide the interworking functions to other oneM2M entities, the IPE shall register to a CSE and communicate with Modbus devices using Modbus protocol. The IPE registration is mandatory in oneM2M systems. Modbus discovery and session establishment are needed for the IPE to communicate with other Modbus applications. A single Modbus IPE may expose Modbus functions provided by one or more Modbus devices to the oneM2M System.
