5.7CPU 922

This section contains the hardware description and technical specifications of the CPU 922 (also known as the R processor).

Details on programming can be found in the CPU 922 Programming Guide.

5.7.1Technical Description

Application	You can use the CPU 922 in single and multiprocessor operation in the
	S5-135U/155U CC (see Chapter 6). Up to four CPUs can be used.
	The CPU 922 is particularly suitable for word processing (closed-loop
	control and arithmetic calculation). Binary signal processing is also possible.
	The following program processing levels are possible:
	S Cyclic
	S Time-controlled (1 timebase)
	S Interrupt-driven (hardware interrupt).
	The programming language is STEP 5.
Design	The module is designed as a plug-in PCB of double Eurocard format. The
	module provides the connection to the S5 bus via two backplane connectors.
	The front plate width is 1 1/3 standard plug-in stations.
