Introduction
Use of the TP 170A
The TP 170A is the basic touch panel for all SIMATIC S7 CPUs. It is the first touch
panel unit in the SIMATIC HMI product range and is based on the operating system
MicrosoftR WindowsR CE.
The TP 170A is suitable for all basic functions. It has an interface which can be used
for both the MPI and the Profibus-DP. The unit memory is designed for smaller
configurations. The objects used for a configuration can be buttons, bar graphs,
graphics and messages.
Area of use of the TP 170A
The TP 170A has been conceived for machine operation and monitoring. It
provides a realistic graphical representation of the machine or system to be
monitored. Its area of use includes implementation in machine and apparatus
construction as well as in the packing and electronics industry.
The high degree of protection (IP65 on the front side) and non-implementation of
moving storage media, such as hard disks and floppy disks, ensure the TP 170A is
also suitable for use in rough industrial environments and directly on site on the
respective machine.
The TP 170A can be installed in switching cabinets and operating consoles.
Due to the fact that the TP 170A is equipped with high performance basic
hardware and has a minimum installation depth means that it fulfills all the
requirements for operation in the vicinity of the machine.

Easy to operate and observe
The TP 170A enables operating statuses and current process values concerning a
connected PLC to be graphically displayed and the relevant machine or system to

be easily monitored and operated. Display and operation of the TP 170A can be
adapted optimally for the respective process requirements by using the
configuration software ProTool/Lite, ProTool and ProTool/Pro CS (from
Version 5.2).
The TP 170A can be used to:
S control and monitor the process intuitively. Setpoint values or control element
settings, for instance, can be modified by entering values or touching configured
buttons;
S display processes, machines and systems graphically;
S visualize operating and alarm messages and process tags, e.g. in output fields,
bar graphs or trend curves;
S intervene directly in the operation by means of the touch-sensitive screen.

Operating unit configuration (principles)
Graphics, texts and operating and display elements which need to be represented
on the operating unit must first be created on a configuration computer (PC or PU)
using the configuration software. The configuration computer must be connected to
the operating unit in order to download the project to the operating unit (refer to
“Configuration phase” in Figure 1-1).
Once the project has been successfully downloaded, connect the operating unit to
the PLC. The operating unit can then communicate with the PLC and respond
according to the information configured for running the program in the PLC (refer to
“Process control phase” in Figure 1-1).
