Answer / mathews

Messung -codesys:Different field busses can be used directly in the programming system CODESYS. For this purpose, the tool integrates configurators for the most common system such as PROFIBUS, CANopen, EtherCAT, PROFINET and EtherNet/IP. For some systems, additional protocol stacks are available in the form of CODESYS libraries which can be loaded subsequently.
