FC3 -Modbus RTU 11 -Addresses Scan

Hello everyone,
I need some advice on how to pass the addresses contained in an Array, defined as List_Address 0..16, to the FC3 block of the MOD RTU 11 library.
Addresses are inside the “List_Address” array. I created a for loop that scans the array from 0 to 16 and if the answer is positive it goes to the next address. But I need to stop the for loop, long enough for it to get the response from block FC3.
Thanks for your help .

Hi,

the FC 3 can be created several times with the corresponding slave address or it has to deactivate the FC after each response, reconfigure it and send it again.
kind regards,
Oliver
