Hello Godie
That is correct, whichCP 343-1 can do whatcan be found HERE
Unfortunately not.
FC11& FC12, if you use a CP as Profinet I/O Controller, see link below for more on this: How do you program communication blocks FC11 and FC12 for the PROFINET IO controller? Last but not least, you may find thelink below helpful: What information is currently available on the topic of PROFINET? I hope this helps |

Thanks a lot for the useful information. I'll try to find any solution with DP master module and so I don't need CP343 1 lean. Best regards |

Hello again Godie I just noticed that you are actually using the ET200S IM151-8 PN CPU (rather than a pureProfinet I/O device). In this case you can do data exchange between it and your CP343-1 LEAN via a unilateral configured S7 connection and usage of FB14/15 GET/PUT calls in the IM151-8CPU(the CP343-1 LEAN can only be a Server for S7 communication so everything will be configured and programmed in the IM151 CPU). Food for thought anyhow and I hope this helps. |

Hello Godie you do NOTexplicitelyconfigure the IM151CPU as a Client nor theCP343-1 Lean as a Server. The Client/Server terms merely describe the way the CPU's will "act" whenthe communication takes place (i.e. ones acts a Client and the other as the Server). What you'll have to do in simple terms is this: 1.) In Netpro configure an S7 connection for the IM151CPU(this is a unilateral connection which thepartner S7-300 with the CP343-1 LEAN will not "know" about norwill you have to download it to the S7-300). 2.) Use FB14/FB15 (GET/PUT) calls in the IM151 CPU to "get"data from the partner S7-300 and to "put" data intothe S7-300 (you will not program anything in the S7-300 which"serves" theGet/Put requests of the IM151 CPU. You will however have to make sure that the requested data areas exist in the partner S7-300). You'll find detailed examples in the links below (and note that the IM151 CPU is technically speaking a S7-300): How do you program communication blocks FB14 "GET" and FB15 "PUT" for data communication on the S7-300? Sample Program: S7 Communication with blocks FB14 ("GET") und FB15 ("PUT") of the CPU 317-2PN/DP I hope this helps |

Hello adidud73 I could only speculate what's wrong, so here are some things to check: 1.)Is there perhaps a physical connection problem (if unsure, unplug the Ethernet cable from the 151-8 CPU, connect your Laptop instead, give it the IP address of the 151-8 and see if you can ping the CP343-1 LEAN) 2.)Is the connection established (check the connection status in Netpro of the 151-8's CPU) 3.) Done, Error, Status of thePUT call are only valid for a one scan, do you havecapture logic for the STATUS word when the Error bit is on? (if not, please add and see what the STATUS says) 4.) Have you checked the CP343-1 LEAN NCM diagnostics and what does it say? (right click on the LEAN in the project, select "properties", go to the Diagnostics tab and click on run) 5.) Are you perhaps out of connection resources in the CPU315/CP343-1 LEAN (check the reserved and occupied connections in the315's CPUs' module information online) 6.) Have you used the correct PUT FB15 in the 151-8 CPU which mustcome from the "Standard library/CommunicationsBlocks"? (check its properties, its family name must state "CPU_300", if it states "CP300PBK" you dragged in the wrong PUT FB15 from the "SIMATIC_NET_CP/CP300"library) That's all I can think of for now, if none of the above helps, pelase upload your S7 project here for evaluation. |
