【profinet】从站开发要点

MRP: Media Redundancy Manager,媒体冗余管理。 MRP 定义了环中节点的类型：一个节点是 Media Redundancy Manager(MRM)， 其它节点是 Media Redundancy Clients (MRC). MRM 监视着PROFINET ring。 Test Packets 成功，表明环是好的， MRM forwards no data between its ring ports。 只要网络连接由MRP恢复的时间小于： 3x cyclic I/O update rate （ othersupplier might 1~10x） ; 则无扰。 PROFINET IO 协议是允许网络间歇中断的。 DAP： Device Access Point LLDP： Link Layer Discovery Protocol (see IEEE 802.1AB-2009) NAP： Network Access Point (PNIO interface with its port submodules, see PNO-7.122 PROFINET IO System Redundancy) SAP： Service Access Point UUID： Universally Unique Identifier (see ISO/IEC 11578:1996) Signal: A process data object with acertain type, for example a UINT32 counter. Terminology and abbreviations ============================= Abstract syntax Describes the parts (and their subparts) of different messages. See also "Transfer syntax". Configuration IO-device and IO-controller definition in an engineering tool. Commissioning Device initialization (Configuration is downloaded to IO-controller). Engineering tool A desktop program for configuring PLC. For example Siemens TIA portal. Interface Abstract group of ports. In Profinet context, interface typically doesn't mean a specific network interface. This is a common cause of confusion. Parameterization Write parameter values to all submodules. Parameterization is done via the Write and Control commands. Port Network interface. The physical connectors are referred to as "physical ports". A "management port" is the network interface to which a controller / PLC connects. Record data Data that can be accessed with acyclic Profinet Read and Write. Addressed by slot, subslot and index.
