SIMATIC S7-400 · POINT-TO-POINT COMMUNICATION
Two-channel CP 441-2 coupling module for serial point-to-point connections
Siemens 6ES7441-2AA04-0AE0 is a SIMATIC S7-400 CP 441-2 coupling module designed for point-to-point communication through two channels. The official product description includes the configuration package on CD and identifies the unit as a repair part. It is intended for installed S7-400 applications where an exact CP 441-2 replacement is required. Before procurement, compare the full order number, channel requirement, fitted interface modules, cable connections, rack slot and STEP 7 project configuration. Siemens currently identifies the product as phased out and at the end of its product lifecycle, so replacement planning should include configuration and spare-part checks.
