Siemens 6ES7 478-2AD00-0AC0 Programmable Logic Controller Module

The Siemens 6ES7 478-2AD00-0AC0 is a TPM 478 interface module that links Teleperm 478 I/O peripherals to the PCS 7 process control system, acting as the bridge between TPM I/O buses and SIMATIC PCS 7 controllers such as CS 275 in M7-400 installations. As part of the TPM 478 family, this module is designed to install in a PCS 7/M7-400 hardware layout to extend remote I/O connectivity and enable coordinated data exchange between field signals and the central control unit. It carries the official order number 6ES7478-2AD00-0AC0 and is intended for use in environments where Teleperm I/O must interface with PCS 7 automation infrastructure, providing a dedicated interface for TPM 478 communication. Typical applications include process control and automated manufacturing tasks in industries like chemical processing, oil and gas, and general industrial automation where legacy Teleperm peripherals are migrated or integrated with PCS 7 systems. In practice, the TPM 478 interface supports integration with CS 275 and Teleperm I/O configurations, enabling reliable signal transfer across the automation stack and preserving compatibility within Siemens’ SIMATIC portfolio.
