The device man- ufacturers supply software drivers, called device type manager (DTM), encapsu for each of its devices or group of devices. The DTM ates the device-specific data, functions, and business rules such as the device structure, its communication capa- bilities, internal dependencies, and the HMI structure. DTMs provide functions for accessing device parameters, configuring and operating the devices, and diagnosing problems. works in order to allow for wireless sensor and actuator access. The WISA specification allows the handling of advanced di- agnostics, parameterization, and variable SA data sizes in the radio telegrams. Using these features together with standard tools such as the IO-Link port configuration tool will enable a high level of integration for a large variety of wireless sensors and actuators. This approach also gives a solution for integration not only for PROFINET IO and PROFIBUS DP but also for other field networks, e.g., CAN/Devicenet, as well. also for other field networks, e.g., CAN/Devicenet, as well. The FDT/DTM technology would allow configuring (Fig. 8) the whole system using communication DTMs and device DTMs representing the different HW components. This re- quires the control system to support fully the FDT/DTM tech- nology, which is not always the case. In the cases where full support is missing, a GSD file could be generated based on the created configuration, e.g., the remote IO communication DTM can perform this task.

Future factory automation installations contain both wired and wireless sensors and actuators, and wireless communi- cation will be present at several levels. In such advanced automation systems, it is important that the different commu- nication technologies are well integrated in order to minimize the engineering efforts. Integrating WISA into PROFINET and PROFIBUS networks according to the principles described in this paper will accomplish this goal. Furthermore, WISA and 802.11 will have to coexist in future PROFINET IO installations, where real-time performance and reliability is crucial. Implementing the suggested improvements for WISA will make the robust technology better suited for this task.
