4.1.2.5 Assignment of the feedback interface
Feedback interface
The user program receives current values and status information from the module via the
feedback interface.
The figure below shows the address assignment of the module in the process image input in
the configuration method 2xCount.
At Counter 0 x stands for the input byte IB 2 in this case, at Counter 1 you add 6 bytes to this
output byte.
When you assign a different start address to the digital input/digital output module, the byte
sequence changes correspondingly.
