Basics Of PROFINET Redundancy

Image
  Overview Of PROFINET system redundancy PROFINET system redundancy standard distinguishes between four configurations with the designation NAP S1,S2,R1 and R2. NAP: Network Access Point means PN interface of Module. It is not the interface IO module but PROFINET Port on the module. If a module has 2 ports acting as a switch then it is counted as 1 NAP. The S (Single) describes and IO device with one PN interface. An R (Redundant) indicates that the IO device has two NAPs: Either 2 interface module each with a PN interface or One interface module with two independent PN interface.  With NAP S2 and Rs, two IO controllers(IOCs) can be assigned to one NAP-a PN interface of an interface of an interface module. It should be noted here that the NAP in operation uses only one of the two connections actively for IO data exchange and switched to the other connection only if there is a failure. Important Note: With system redundancy, the IO controller (IOC) – in other words the PN inter...

TYPE OF RACK IN S7-400 SYSTEM When using ER's, you need interface modules (IMs) as well as the additional racks, and additional power supply modules if necessary. The rack containing the CPU is known as the central rack (CR). The racks containing modules in the system and connected to the CR are the expansion racks (ERs). Below are the details of Send and Receive IM with distance and maximum connections   SEND IM IM 460-0 IM 460-1 IM 460-3 IM 460-4 RECEIVE IM IM 461-0 IM 461-1 IM 461-3 IM 461-4 Max Number of Connection per EM 4 1 4 1 Max Distance 5 m 1.5 m 102.25 m 605 m 5 V transfer No Yes No No Communication Bus Yes No Yes No   Rules: You can connect up to 21 ERs of the S...
