Its 450 MHz multi-processor CPU runs the communication stack and the safety logic for PROFIsafe, so this single module manages both standard and safety I/O on the same bus line. ## Fieldbus and safety profile PROFIBUS DP is native — no add-on module needed. The module also supports acyclic parameterisation and diagnostics. PROFIsafe runs over the same PROFIBUS cable, so a safety CPU can communicate with F-I/O modules through this interface without a separate safety bus. The module can act as both a PROFIBUS DP client and server. For TCP/IP and UDP communication, the module uses the integrated PROFINET interface and loadable function blocks. MODBUS RTU is available via an add-on. S7 routing is supported, which lets the module forward data between PROFIBUS and other networks in the TIA Portal topology. ## I/O capacity and system limits The module handles up to 16 kbyte of inputs and 16 kbyte of outputs, with the actual maximum depending on the System Expansion Card fitted. It supports 8 concurrent RDREC (SFB 52) and 8 WRREC (SFB 53) operations per interface, with a total cap of 32 across all external interfaces. The overall number of modules in the ET200S station is 120. System diagnostics are handled through SFC 51 (RDSYSST) with 8 concurrent calls, and the SysLog function supports up to 4 TCP receivers with a buffer capacity of 3 200 entries. Operating temperature range is 0 °C to 70 °C. The module carries CE mark, cULus, and CCC approvals. It is ATEX certified for Zone 22: ATEX II 3G Ex ec IIC T4 Gc, which means it can be installed in a non-hazardous area with connections into a potentially explosive gas atmosphere — relevant for chemical and pharmaceutical lines where the ET200S rack sits outside the classified zone.","metaTitle":"Siemens 6ES7151-1BA00-0AB0 SFB Interface Module, PROFIBUS DP","metaDescription":"Siemens 6ES7151-1BA00-0AB0 SFB interface module for ET200S.
