    Appendix A PROFINET IO technology Introduction to PROFINET As a common solution for the industrial communication, the PROFIBUS International organisation introduced the PROFINET Industrial Ethernet standard. PROFINET is the next step for building on the current: • PROFIBUS DP, the well-known and established fieldbus; •...

    In these protocols, the networks are identified based on the IP address. Within a single network the MAC address is used for the addressing of the target devices. This addressing features enables integration with the IT world without limitation. The OMRON I/O Devices can accordingly support the OMRON Ethernet protocols, enabling additional communication with OMRON PROFINET devices.

    PROFINET Distributed I/O The focus of PROFINET IO is to have cyclic data exchange between a controller and multiple often simple communication devices. The aim is to have high performance and ease to use. The experience of the PROFIBUS fieldbus has been integrated into the PROFINET IO from user’s point of view. The PROFINET IO distinguishes the following different device roles.

    PROFINET Communication Services The IO Controller establishes a connection to its IO Devices based on the configuration which has been given by the user. The Application Relation (AR) includes all data needed to achieve this data exchange. A single AR can include multiple Communication Relations (CRs).

    Alarms PROFINET IO is capable of sending events within the automation process as alarms. These alarms have to be acknowledged by the application process. These include both system-defined events (i.e. Removal of slices) or user-defined events (i.e. Input voltage out of range). The following events are distinguished: Type Description...

    FDT/DTM Technology The FDT/DTM concept specifies the interface between the engineering systems called Field Device Tools (FDT), and the device-specific software components called Device Type Managers (DTM). FDT/DTM is the most recent advancement in Configurators. The FDT/DTM concept separates the device-dependent functionality (which is in the DTM) from the application. It provides separate interfaces for device configuration, monitoring and maintenance solutions, which before largely depended on the manufacturer of the application.

    Appendix D Memory Card Backup Functions Outline of Function The PROFINET IO Controller Unit stores the following setup data in the internal non-volatile memory (Flash ROM). • PROFINETIO Connection Parameters set; • Allocated IO Device Parameter sets. All these parameter sets can be backed up to and restored from a Memory Card mounted to the CPU Unit. If the parameter data of a good functioning PROFINET IO Controller Unit has been saved on a Memory Card, this saved data can be used to perform a quick configuration, when replacing the PROFINET IO controller Unit, without the direct use of the Configuration software.
