The Siemens 6SE6400-1PB00-0AA0 PROFIBUS DP Interface Module is a plug-in option for MICROMASTER 4 frequency converters that adds a PROFIBUS DP communication link between MM4 drives and a higher-level controller (MM420/MM430/MM440). For mechanical reasons, MM4 FX/GX installations require the use of plug 6GK1500-0EA02. The module is documented as a PROFIBUS DP interface for MICROMASTER 4, with notes on EMI/interference immunity in accordance with relevant standards, supporting integration of MM4 drives onto PROFIBUS networks.
