The 6ES5526-3LF01, also known as the CP526-2, is a communications processor in the Siemens SIMATIC S5 series. 

It is used in S5-DOS systems and specifically supports system communications with older monochrome monitors.

The 6ES5373-0AA61, a 64KB EPROM memory module in the S5 series control system, is used to store system 

programs and configuration data. It has also been discontinued.

These two products are typically used in combination: the CP526-2 handles communications processing, while 

the EPROM module stores essential system code. Together, they ensure stable operation of the S5 controller and its terminal user interface.
