Hi, i am beginner with WinCC and i need help, i connected the Temperature transmitter with a SM331 module on PLC so i can read a temperature value in STEP 7. I use FC105 block to read temperature value and all that is working properly. Now i need to display that value in HMI. I am using WinCC v5.0 to do that, specifically the ''I/O Field'' in WinCC. I am using the MPI Communication to connect WinCC with a PLC, but i cannot get the Temperature value in a I/O Field. I always get zero value. Here are the pictures:
1. HW Config
2. FC105 block
3. MPI Connection
4. Tag for the FC105 block
5. I/O Field properties
What am i doing wrong?
