2. Expandable any time
STEP7 Lite is designed for non-
networked automation solutions.
Typical applications are those with
SIMATIC S7-300 in a centralized
arrangement with digital and analog
inputs/outputs. SIMATIC C7 and the
intelligent probes of ET 200 S/X can
also be programmed. LAD, CSF and
STL are available as a programming
standard. In terms of simulation and
diagnostics there are no restrictions
compared with STEP7.
If the tasks should become more
complex, you simply upgrade to
STEP7. Your investment in the know-
how is secure, as your data can be
transferred.
Intuitive operation
Work productively from the start: STEP7 Lite makes it possible. It’s easy. The
hardware is configured completely graphically. The representation on screen
corresponds to the real controller. Everything is clear at a glance. To navigate,
you use the register technology familiar from Office: screen views can be switched
without the danger of losing the overview. STEP7 Lite is thinking all the time:
color changes immediately indicate if obvious operating errors have been made.
SIMATIC® and STEP7 help professionals to perform any automation task. Quickly and efficiently –
no matter how complex. New users start with smaller tasks – STEP7 Lite guarantee success here
too. STEP7 Lite facilitates your entry into PLC technology – and does not hold you back
if you want more: simply upgrade to the full STEP7 and carry on at a professional level.
That is why you should choose STEP7 Lite.
Easy to learn
The STEP7 Lite user interface is designed
with great clarity to help you learn
intuitively and achieve swift success.
In no time at all, you will feel confidently
in control of the software.
STEP7 Lite: for a fast and efficient transition from task to solution.
