The embedded SoftPLC
All OPENcontrol units include a
powerful SoftPLC fully integrated with
the system and sharing the hardware
resources. The real-time multi-
tasking SoftPLC is programmed using
“4Control”, a graphical environment
based on IEC 61131-3, to develop
the machine logic using standard
languages (IL, LD, ST, FB, SFC).
The tool includes debugging functions
such as break points, tracing,
viewing of variables using point &
click operation and utilities such as
modifications “on the fly” and “warm start” of logic that speed up the commissioning of
the machine.
The organization of the integrated real-time machine logic environment permits the
execution of up to 250 parallel tasks, with 10 different levels of priority and cyclical
scheduling time that can be as fast as 250 microSec.
The M, S, T functions from Part Program, motion acknowledgment, console commands
and generally all the asynchronous system requests are communicated to the PLC by
event tasks. The fast execution, respecting the required priority, reduces the execution
time of the part program which increases machine productivity.
The OPENcontrol PLC allows the creation of real application programs that interact with
the system at all levels:
Data Exchange and synchronization with the HMI and with the processes managing
the part-program execution
Tool and Offset management
Axes motion from logic (point to point, interpolated, start/stop on event, master/
slave, CAM)
Sharing and motion of Coordinated Axes (axes used for ISO program execution)
Interaction with Coordinated Axes interpolators
Management of peripherals and data files in text, binary or XML format
Communication with other devices through local network.
An extensive library of more than 400 functions allows effective control of the whole
system and the ability to modify its standard behaviour to adapt it dynamically to the
application requirements.
