2025年3月9日 · K-Bus (SPS) From Wikipedia, the free encyclopedia The K-bus (also called communications bus) is a term coined by automation. About a K-bus there will becomprehensive exchange of data. In PLC technology, this bus, the task of exchanging data between the CPU of a PLC and its associated function and communication modules is realized.

2006年11月27日 · In my program, I have established a data transfer between the CPU 416-3 DP and the FM 458-1 DP via peripheral addresses. I know that in this case the P-bus is used and not the K-bus. So i just want to know the main difference between the P-bus and the K-bus. Thank you: Suggestion; To thank ; Quote; Answer

2006年11月27日 · Communication: bus (K-bus) The communication bus (also K-bus) has the task to manage the acyclic. data exchange to:• CPs • IP / FMs and • Other CPUs. A bus system is available here which also allows for connections. between the stations without using the CPU. Communication: P-bus (I/O bus) The P-bus (I/O-bus) is responsible for the data ...

2000年3月28日 · Which communications services can be set up with the S7-400 via the K bus? ANSWER: You have several S7-400 CPUs slotted in a common rack. You want to set up communication between the CPUs via the K bus (backplane bus of the S7-400). The following communications services are possible via the K bus: Global data communication (GD):

2010年12月11日 · MPI interface instaled on CPU-board and not used K-bus. But, kommunication by MPI make CPU max 187.5Kbod, by ethernet (formation exchange protocol ) - make CP (CPU only send data to cp). in this case CPU is loaded exchange less. But there is a "bottleneck" - K-bus has speed 187.5Kbod (speed ethernet - up 100Mbod.

2010年7月2日 · The P-Bus and the K-bus (internal MPI bus) are running inside these jumpers.

2010年10月5日 · Hello gre_m don't worry too much about the "slow" K-bus speed in an S7-300. While it usedfro some communicationsbetween the CPU and CP's, the user data that you read from the CP is actually transfered via the the fast I/O related P-Bus (you'll notice that any CP in an S7-300 occupies 16 bytes of I/O space which is used for this purpose).

2011年10月2日 · K-Bus (SPS) From Wikipedia, the free encyclopedia The K-bus (also called communications bus) is a term coined by automation. About a K-bus there will becomprehensive exchange of data. In PLC technology, this bus, the task of exchanging data between the CPU of a PLC and its associated function and communication modules is realized.

QUESTION: With STEP7, how do I configure a global data communication of several S7-400 CPUs via the common K bus? ...

2015年8月5日 · There are two types of K-Bus:-the K-Bus is performed as "partyline", that means it is physically wired to the MPI-Interface. This structure you will find in CPU312 - 315-2DP-the K-Bus is not performed as "partyline", that means K-Bus and MPI-Interface are disconnected. This structure you will find in CPU315-2PN/DP - 319-3PN/DP. hope this helps,
