Siemens 6GK1243-3SA00 Communication Processor

Siemens CP2433 (6GK1243-3SA00) is a SINEC S1 master module that functions as the communication processor for connecting SIMATIC S5-90U, S5-95U, S5-100U and ET200U to an AS-Interface network. This AS-Interface Master enables the host S5/ET200U to address and exchange data with AS-i slaves, integrating older Siemens controllers into AS-i fieldbus layouts. The CP2433 is documented as part of the CP2433 family with vendor master profiles including M1 with a function block and M0 without, providing flexible configuration for interface logic. It bears the vendor order number 6GK1243-3SA00 and carries CE marking for EMC (directive 89/336/EEC) in industrial environments, with installation guidance referencing the SINEC S1 CP master manuals and system handbooks for S5-90U, S5-95U, S5-100U, and ET200U. Designed for robust industrial use, CP2433 offers a dedicated, standards-aligned bridge between S5 controllers and AS-i devices, enabling reliable automation setups that extend legacy systems with modern fieldbus connectivity.
