Hello experts,

I am working on the communication between a 314C-2DP CPU +CP343-1 with 3ET200s by profinet.

The hardware configuration of my Et200s is the following

DI:4DI per Et200s : address range from 0 to 3

DO:4DO per Et200s : address range from 0 to 3

Analog output voltage (+-10V) :2AO per Et200s .

My question is the following:

Since the FC11 and FC12 functions only send and receive data in bit form, do I have to convert the bits into integers for the et200s analog output boards?

These output cards should provide me with a 0-10V signal for my remote speed controller.

I have 3 drives in this example and I want to assign each one a FB function and 3 datablocks for each drive (DB1,DB2 and DB3).

In addition to the FC11 and FC12 functions I should also call in OB1 the block function FB100 to manage the drives with their respective DB.

Can you help me with the order of calling functions and block functions?

thanks
