S5-115F Manual
1.3.2
Central Processing Unit
The central processing unit (CPU) is the "brain" of the programmable controller. It executes the
control program.
The CPU 942F is used in the S5-115F. This is a slightly modified version of the CPU 942 in the
S5-115U.
•
PG/SINEC L1 interface optocoupler, for reliable electrical isolation
•
No 5.2 V supply for the SINEC L1 terminal on the interface connector (so that the SINEC L1 LAN
does not bypass the reliable isolation, even in the event of a fault)
•
Operating system with all the safety functions of the S5-115F
You can use the CPU 942F in combination with analog modules and closed-loop control software
to control nonsafety-related processes. A PID algorithm is integrated in the operating system of
this CPU. Time constants starting at approximately one second are possible. You can implement a
maximum of eight control loops.

Input and Output Modules
Input and output modules are the interfaces to the sensors and actuators of a machine or
controlled system.
The following features make S5-115F modules easy to handle:
•
Fast installation
•
Mechanical coding
•
Large labeling areas
Digital Modules
Digital modules conform to the voltage and current levels of your machine.
Digital modules have the following convenient features:
•
Connection of signal lines via front connectors
•
A choice of screw-type or crimp snap-in connections
Analog Modules
As a programmable controller's degree of performance increases, so does the significance of its
analog value processing. The significance of the analog input and output modules increases
accordingly.
The S5-115F offers the AE 460 and 463 nonfloating analog input modules. The desired level for the
AE 460 is set via range cards and for the AE 463 via jumpers in the front connector. A range card is
required for each of the four channels on the AE 460. This feature allows you to do the following:
•
Have up to two different measuring ranges on one module.
•
Change the measuring ranges simply by exchanging range cards.
In the case of the AE 463, the measuring range is jumpered separately for each of the four
channels.
One analog output module covers the various voltage or current ranges of analog actuators.
