Dear friends: I have problems with get a data in the sentron PAC. Im using a CPU 315 2DP, power pac with profibus module, the connection to the power pac is OK (sw, hw and step 7 program) , Im using the basic type 2 telegram. I can read the data for voltaje and power factor But I can´t read the double float data (64 bits real data).!!! Do you have some ideas?

Hello AutoGen_878646, Have you already read this: How can you process 64-bit floating-point numbers in STEP 7 V5.5 with a SIMATIC S7-300/400 CPU? or you could try with the OSCAT library, surely there are functions to handle 64-bit variables: If I remember correctly is under Math Double Precision |
