Siemens 6ES7962-3AA00-0AC0 Programmable Logic Controller Module

Siemens 6ES7962-3AA00-0AC0 is the IF962-COM interface module for SIMATIC M7-300/400 controllers, delivering two RS232 serial interfaces for backplane-mounted communication. Designed to plug into an M7-300/400 rack, it extends the controller's serial I/O capabilities to support asynchronous data exchange with external devices via RS-232 signaling. Identified by the 6ES7962-3AA00-0AC0 part number, this module is a dedicated Schnittstellenmodul in the Siemens M7 family, built to operate alongside other M7-300/400 modules and CPUs. In typical automation setups, IF962-COM enables point-to-point serial communication with devices such as printers, modems, sensors, or third-party controllers that speak RS-232, enabling data transfer, status reporting, or control commands from the M7-400 system. The module’s two independent RS232 channels provide parallel serial paths, allowing separate devices or subsystems to be queried or controlled concurrently without port contention. As part of the M7-400 modular platform, it leverages the M7 backplane and the system’s addressing and interrupt framework to integrate serial communication into the broader control program. This combination of dual RS232 ports, M7 compatibility, and Siemens engineering makes the 6ES7962-3AA00-0AC0 a focused solution for extending serial connectivity within Siemens SIMATIC M7 installations.
