The CAN J1939 Protocol provided by CODESYS and its Online Help documentation is delivered in a separated Add on that can be installed on top of SoMachine V4.1 SP2, 4.2 or 4.3. This protocol is supported on M241/M251 controllers only. This add on is free of charge. It will neither be shared on SESU nor www.schneider-electric.com, only through ADEs, SAEs and customer support.
