You will find the basics and additional information on the counting function in the function manual Counting, measuring and position detection (http://support.automation.siemens.com/WW/view/en/59709820). Counting with channel 0 and channel 1 You control the counting function via the IO addresses of the module. These IO addresses are also known as the control interface (output addresses) and feedback interface (input addresses), see section AUTOHOTSPOT.
You can find information on wiring the front connector, creating a cable shield, etc. in the Wiring section of the S7-1500/ET 200MP (http://support.automation.siemens.com/WW/view/en/59191792) system manual. Wiring and block diagram The figure below shows you how to wire the module and the assignment of the channels to the addresses (input byte a to input byte b).
Wiring Resistor circuitry of the encoders To detect a wire break, it is necessary that enough quiescent current is flowing even when the encoder contacts are open. Connect a resistor of 25 kΩ to 45 kΩ with 0.25 W to the encoder contacts for this reason.
Parameters/address space Parameter 4.1.1 Parameters DI 16x24VDC HF parameters When you assign the module parameters in STEP 7, you use various parameters to specify the module properties. The parameters that can be set depend on whether you use the module in standard mode or in counter mode. You will find the parameters in section Parameters DI mode (Page 17) or section Parameters of the Counting mode (Page 19).
