Area of Application for the S5-155U with the CPU 948
SIMATIC S5 family
Suitability
1 - 4
The S5-155U programmable controller belongs to the family of
SIMATIC S5 programmable controllers. With the CPU 948, it is the
most powerful multiprocessor unit for process automation (open and
closed loop control, signalling, monitoring, logging).
Owing to its modularity and high performance, it can be used for
medium to extremely large control systems as well as for complex
automation tasks at the plant and process supervision level.
The S5-155U with the CPU 948 is particularly suitable for the
following:
• • Tasks requiring fast bit and word-oriented processing and fast
reaction times, i.e. with extremely fast open and closed loop controls.
Examples of this are fast processes in mechanical engineering
(bottling plant, packing machines or similar systems) and in the
automobile industry.
• • Tasks requiring an extremely high storage capacity and fast access
times, e.g. in the automobile industry, process and plant
engineering.
• • Tasks requiring fast communication with other CPUs installed in
the PLC and operating in the multiprocessor mode and with CP
modules (e.g. when connected to bus systems, host computers, for
visualization, operation and monitoring).
• • Complex tasks which can be handled efficiently and clearly using
the high level languages C and SCL.
