S5 Serial Communication Processors

(CP 521, CP 523, CP 524, and CP 525)

These S5 communication modules can be used for point-to-point serial data

communication with a peripheral device by using a current loop or RS-232

interface. They are often used to send messages to a serial printer. The CP 524

and CP 525 can be configured to communicate with another controller in

another rack.

Serial Communication Memory Submodule

The communication processors have receptacles for memory submodules that

provide the extra memory capacity required for parameter assignment data and

message texts. The configured data is transferred from the memory

submodule to the communication processors on startup. These memory

modules have a maximum capacity of 16 KB.

Serial Interface

The S5 communication processors connect to a peripheral device over a serial

interface that can be a TTY current loop interface or an RS-232C (V.24)

interface. The TTY 20mA current loop interface is no longer used in modern

peripheral devices.

The signals of both interfaces are transmitted over a common subminiature D

socket connector.
