Appendix B: Backward Compatibility 51 (114)
B 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, when
designing with both series in one application, or when adapting a 30 series application for the
40 series.
B.1 Background
B.1.1 Anybus CompactCom 30-Series
The Anybus CompactCom 30-series concept was introduced in 2005 and is based on the NP30
processor from HMS Industrial Networks AB. The concept supports various fieldbuses and
industrial Ethernet networks. The Anybus CompactCom 30-series fieldbus and industrial
Ethernet solutions today offer a good level of performance and is used by many customers.
B.1.2 Upgrade to the 40-Series
During 2013, HMS Industrial Networks AB introduced the new Anybus CompactCom 40-series
which presented a high performance solution with very low latency, extended APIs, and the
ability to meet the future demands of industrial networking. In addition to the new APIs, the
Anybus CompactCom 40-series supports the same APIs as the 30series, offering a possibility
to enable present Anybus CompactCom 30 applications an easy upgrade to the latest
technology.
B.1.3 Access to Real-time Ethernet, IIoT and Advanced Security Features
The Anybus CompactCom 40-series is based on the NP40 processor which is the foundation
for the high performance and extended functions offered by the 40-series. Future technologies
and demands of advanced network functions, IIoT solutions, and advanced security features
will be incorporated in the Anybus CompactCom 40-series.
B.1.4 Recommendations from HMS Industrial Networks AB
For new designs the Anybus CompactCom 40-series is the recommended platform for
communication, but the compatibility between the two series enables usage of both series in
one product. This document describes the differences between the CompactCom 30-series and
the CompactCom 40-series in order to add guidance on how to modify an existing product to
support the latest 40-series modules in addition to existing 30-series support.
B.2 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:
