Freelance
Process automation made easy
Freelance is a full-fledged distributed contr ol system that combines
the advantages of both worlds - DCS and PLC It of fers the small
footprint of a PLC, together with the full functionality of a D CS.
The integrated environment simplifies engineering, commissioning,
maintenance and fieldbus management. The intuitive operator
interface enables easy operation and diagnosis of the entir e system.
a few I/Os to a large system of up to thousands of I/Os.
Expansion can be done with minimal engineering effort.
A Freelance system can consist of one or combination of
several AC 700F, AC 800F and/or AC 900F controllers. It can
be extended with fieldbuses, field devices and r emote I/Os.
With AC 800F and AC 900F, you have the option of configuring
your entire system in r edundancy.
As shown in the architecture drawing (see pages 8-9), Freelance
can go from a typical OEM offering with an AC 700F controller,
a Panel 800 and around 50-100 I/Os. The AC 700F can have
up to eight dir ect I/O modules connected to it or have r emote
I/Os connected via PROFIBUS. Modbus R TU and TCP ar e also
supported. The Freelance Lite offering can typically have an
AC 700F or AC 900F controller and will be in the 250 to 400 I/O
range with possibly a combination license and a few operator
stations. This can ramp up to the Fr eelance Standard and
Premium offerings with the AC 800F and/or AC 900F, with or
without redundancy. Freelance can go up to thousands of I/Os.
Connections include Foundation Fieldbus, PROFIBUS and
Hart as well. Ther e is also the possibility to connect to super -
