Backward Compatibility
Appendix H. Backward Compatibility
The Anybus CompactCom M40 series of industrial network modules have significantly better performance and
include more functionality than the modules in the Anybus CompactCom 30 series. The 40 series is backward
compatible with the 30 series in that an application developed for the 30 series should be possible to use with
the 40 series, without any major changes. Also it is possible to mix 30 and 40 series modules in the same
application.
This appendix presents the backwards compatibility issues that have to be considered for Anybus CompactCom
40 PROFINET IRT, when designing with both series in one application, or when adapting a 30 series application
for the 40 series.
1. Initial Considerations
There are two options to consider when starting the work to modify a host application developed for Anybus
CompactCom 30-series modules to also be compatible with the 40-series modules:
• Add support with as little work as possible i.e. reuse as much as possible of the current design.
– This is the fastest and easiest solution but with the drawback that many of the new features available in the
40-series will not be enabled (e.g. enhanced and faster communication interfaces, larger memory areas, and
faster communication protocols).
– You have to check the hardware and software differences below to make sure the host application is
compatible with the 40-series modules. Small modifications to your current design may be needed.
• Make a redesign and take advantage of all new features presented in the 40-series.
– A new driver and host application example code are available at
new communication protocol. This driver supports both 30-series and 40-series modules.
– You have to check the hardware differences below and make sure the host application is compatible with
the 40-series modules.
NOTE
This information only deals with differences between the 30-series and the 40-series.
