Example 4 - valve terminal with 16 valves (outputs) and 32 repeaters (inputs), every second repeat signal
not taken into account
• PROFIBUS-DP address 7
• The valves 1-8 are assigned to outputs (PAA) byte 17 in the process image.
• The valves 9-16 are assigned to outputs (PAA) byte 10 in the process image.
• Repeaters 1, 3, 5, ... 15 are assigned to inputs (PAE) byte 18 in the process image.
• Repeaters 1, 17, 19, ... 31 are assigned to inputs (PAE) byte 21 in the process image.
• Mode: Halved inputs
• Input filter active
