Appendix A: Implementation Examples 43 (114)
A Implementation Examples
A.1 General
In this appendix HMS provides examples of possible implementations for the Anybus
CompactCom M40 series. Some of the examples can also be used for the Anybus
CompactCom 30 series, showing that the modules from the two product families in some
contexts are interchangeable.
There are many different processors with different functionality available on the market today.
The implementations in this appendix are to be regarded as examples that are designed for one
single type of processor. Other hardware interfaces may require adjustments for timing,
different functionality etc. It is important to fully understand the interface to take correct design
decisions in order to obtain a stable and reliable design.
A.2 Design Considerations
It is recommended for Anybus CompactCom M40 users to make sure that each signal
controlling the Anybus CompactCom M40 has a drive strength enough to fulfill level and timing
constraints even if the signal is loaded with 20 pF in parallel with 2.2 kΩ to GND or 3V3.
