10.4 Deployment as PROFINET I-Device10.4.1 Steps of configuration– With firmware version V2.4.0, there is a PROFINET IO controlleravailable via the Ethernet PG/OP channel.– As soon as you use the PROFINET functionality via the EthernetPG/OP channel, this affects the performance and response time ofyour system and due to the system the cycle time of the OB 1 isextended by 2ms.Range of functionsPlease regard that the PROFINET IO controller supports only thePROFINET functions, which are described in this manual, even if the Sie-mens CPU, which is used for configuration, offers further functions! Touse some described PROFINET functions, it is necessary to deployanother Siemens CPU for configuration. Here, however, is pointed toexplicitly.The I-Device (Intelligent IO device) functionality of a CPU allows data to be exchangedwith an IO controller, which are preprocessed by the CPU. In this case, the I-Device isconnected as an IO device to a higher-level IO controller. The process values recorded incentral or decentralized periphery can be preprocessed via a user program and madeavailable to the higher-level PROFINET IO controller by means of PROFINET.n The configuration of the integrated PROFINET IO controller of the VIPA CPU as an I-Device is made via a virtual PROFINET devices, which is to be installed by means ofa GSDML from VIPA in the hardware catalog.n The communication takes place via input/output areas, which are defined in the I-Device.n The size of the areas for input and output data is max. 768byte.n The I-Device is made available to a deterministic PROFINET IO system via aPROFINET IO interface and thus supports the real-time communication Real-Time.n The I-Device functionality meets the requirements of the RT class I (A) and corre-sponds to the PROFINET specification version V2.3.n The configuration of a VIPA PROFINET CPU as an IO controller and at the same timeas an I-Device is possible. The influence of the I-Device configuration on the systemlimits or performance of the PROFINET controller is equated with that of a device.This means that when the IO controller and I-Device are used at the same time on thePROFINET controller, the I-Device is to be regarded as an additional device for deter-mining the system limits.n In order for the higher-level IO controller to communicate with the VIPA I-Device, thefollowing must be observed:– I-Device and higher-level IO controllers must be configured in different networks.Their IP addresses must be in the same IP circuit.– The device name of the PROFINET controller of the I-Device must match thedevice name of the I-Device at the higher-level IO controller.The configuration of the PROFINET IO controller as I-Device should be done by the fol-lowing procedure:1.
