Calculation of the free bytes in the address space
Table A-20 Example for CFU PA: CFU PA with counting functionality without field devices
Slot Type Allocated bytes in the input address
space
Allocated bytes in the output ad‐
dress space
0 Diagnostics address 1 1
X1 Diagnostics address 1 1
X1 P1 R Diagnostics address 1 1
X1 P2 R Diagnostics address 1 1
1 Input and output address 6+1 6+1
2.1 Diagnostics address 1 1
2.2 Input and output address 4+1 2+1
Total: 17 15
Free bytes in the process image (for field devices):
Input address space: 1440-17 = 1423 bytes (or 983 bytes in S2/CiR mode)
Output address space: 1440-15 = 1425 bytes (or 985 bytes in S2/CiR mode)
