Dear Sie, i have CPU 317-2PN/DP for Milling Section I have CPU 414-3PN/DP for Main Process Section I want to receive data from CPU 317-2PN/DP to CPU 414-3PN/DP over ethernet (Pofi net port). which instruction should i use to send & receive data to & fro? how should be the Hardware configuration( connections & setting in hardware & netpro) please post sample configuration & program is this case is only solved through Open communcation wizard or what is other method rahul Splitted from Open Communication Wizard Issues.

Hello Raul0905 there areother methods and you can also use S7 communication (e.g GET/PUT, BSEND/BRECV and/or USEND/URECV) as well as Profinet I/O based data exchange. The CPU-CPU communication with SIMATIC controllers (compendium) has all the possible communciation ways listed in it and will hopefully come in handy now and in the future and below are a few selectedexample links: How do you program communication blocks FB14 "GET" and FB15 "PUT" for data exchange in the S7 program of an S7-300 CPU? Sample program: S7 communication with the blocks SFB14 ("GET") and SFB15 ("PUT") with S7-400 Simatic Net Quickstart collection Once you decide on which way you want to implement the comms, it wont hurt to do a search for the relevant comms blocksas you may find more examples. I hope this helps |
