It breaks out two ECOFAST connections for PROFIBUS DP via RS485, with an integrated address setter and terminating resistor on board. That terminating resistor is the part that keeps the bus free of reflections—without it you're guessing where to add or remove termination on the drop cable, and signal integrity suffers. ## Field-signal reality for ET 200 PRO This module lives on the PROFIBUS drop for an ET 200 PRO interface module (IM 154-1 or IM 154-2). The two ECOFAST connections let you daisy-chain or stub-connect field devices with a rugged bayonet-style connector. Because the terminating resistor is built in, you don't need an external T-piece with a separate terminator—one less component to fail or get misconfigured during commissioning. The address setter is also integrated, so you program the station address locally via rotary switches instead of relying on software assignment alone. That makes swap-out quicker: pull the old module, set the same address on the new one, and the bus sees the same station ID.","metaTitle":"Siemens 6ES7194-4AA00-0AA0 SIMATIC DP Connection Module, Act","metaDescription":"SIMATIC DP connection module for ET 200 PRO with ECOFAST connections, integrated PROFIBUS DP address setter and terminating resistor.
