Compact PLC – The open and
closed-loop control system
Compact PLCs are all-in-one devices that, even in their
basic version are equipped with a comprehensive set of
hardware and software functions and thus suitable for
use in many control, regulating and measuring
applications. Where the integrated functions do not
suffice, the devices can be simply expanded either
locally or via network.
The range includes:
Compact PLC – PS4
LE4 – local expansion units
EM4 – distributed expansion units.
All the compact PLC are networkable and programmable
via integrated fieldbus. The programming software
applicable to all is Sucosoft S40, an easy-to-use
programming package to IEC 61131-3.
