Hello, I have a ET200SP CPU 6ES7510-1SJ01-0AB0 with a CM DP 6ES7 545-5DA00-0AB0 that is needs to send datas to a S7 400-CPU-412-2XJ05-0AB0 via PROFIBUS. The ET200SP CPU should be SLAVE and the S7-400 CPU should be MASTER. I have assigned transfer area with adresses so that the slave can send data to the master and I am only using move instructions but the communication seems to not be working. Are there any specific instructions to be used to be able to send the data ? ------------------------------------------------------------------------------------------ |

Hi, will Slave be recognized by S7-400 PLC? Did you check size of precess image for input or outputs? There is also an example for using CM with S7-400: How to you connect the communication module CM 1542-5 or the communications processor CP 1542-5 as I slave in STEP 7 V5.x to an S7-300/S7-400 CPU?Regards, Towome |
