Product Overview
Description
The Siemens 6ES5521-8MA21 is a SIMATIC S5 CP 521 SI communications processor for serial data exchange. It links the control system with devices such as printers and terminals through RS-232C (V.24) or TTY communication. The module handles both printer output and bidirectional data traffic, allowing process messages, variable values and other serial data to move between the PLC and external equipment.
