Connecting FC 105 block with I/O Field in Wincc V5.0

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?

In run mode of wincc
At the top of the wincc configuration editor
What's the connection status?

In your connection parameter you should have the slot address set to 2 I believe

in your connection parameter you should have the slot address set to 2 i believe

+1

Good catch

thanks , i will try with that change, i hope it's gonna work

hi, again me, i set the slot adress to 2, but again i get zero value, does anyone know what else could be a problem?

Monitor PIW288 in a VAT table to verify you are getting a value from the analogue input.

i have monitored FC105 block in Step 7 with Monitor icon (goggles)and i get the value on the PIW288, also i get scaled value on the MD240 so the FC105 block is working properly, i just can't get value from MD240 in the WinCC I/O field and i don't know why...
