Hello Jonas; To supplement Hati's very correct answer, you must use the CPU parameters interface (in HWConfig) to "reserve" the digital inputs for counting (once they are reserved they cannot be used for normal input signals), and to determine what type of counting you will implement. As long as no input is reserved for counting (or other) applications, then they can be used for normal digital processing. The screenshot below is taken from this manual, which also contains much information on the Counting functions available for the CPU 314C-2xxxx in section 5, Counting, Frequency Measurement and Pulse Duration Modulation: SIMATIC S7-300 CPU 31xC Technological Functions https://support.industry.siemens.com/cs/us/en/view/12429336 Hope this helps, Daniel Chartier |
