Here's a process controller that uses past experience to make decisions that eliminate costly
problems like overshoot. The Fuji Electric PYX Series uses a type of artificial intelligence called
"fuzzy logic" to learn your system's particular characteristics, and works with that knowledge to
obtain the proper results.
During autotune (a procedure which automatically fine-tunes your controller) and during normal
operation, the Fuji Electric PYX Series is studying your system's responses to changing conditions.
It remembers how the system responded at start-up and to disturbances (such as opening an
oven door). Once it gets to know your process, the Fuji Electric PYX Series controller actually
anticipates the extent of the fluctuation and takes corrective action before a minor deviation
becomes a major problem. That means an end to troublesome overshoot — even the minor
overshoot associated with PID control. It also means a virtual lock on the target setpoint once
it's been reached, without wandering.
The Fuji Electric PYX Series also boasts a host of other indispensable features. Users can input
an eight-segment program that leads a process smoothly through a predetermined series of
thermal steps.
And when it comes to communicating with a computer, the PYX is unsurpassed. Along with the
RS-485 communications option, we provide free software that lets you monitor up to 31 controllers
at the same time. As with our simple front panel keypad menu, the software can be installed and
run easily even by first-time users.
FREE PYX-LITE Data Logging Software
Windows™-based PYX-LITE supports Windows DDE (Dynamic Data Exchange) and provides data
logging output in an easy-to-use comma-delimited format. It supports up to 31 PYX controllers
from a single workstation and is capable of displaying all 31 controllers simultaneously. PYX-LITE
offers both Supervisory Mode for viewing the entire network at a glance and Single Station Master
Mode for viewing all parameters for one controller on a single screen. It allows personnel to set-up,
monitor, and control the entire PYX network from a single workstation on only two wires (RS-485
communication).
