This document describes the application of CALgrafix on plastic extruders, introducing temperature controllers, variable speed drives, pressure transducers and their relationships.
The note describes the use of CALgrafix, an OPC‑based Windows package, to control temperature zones, pressure and screw speed on plastic extrusion lines. Controllers manage heating and cooling, while the software provides centralized monitoring, charting, logging and alarm functions.
Networking features are covered, including OPC client/server architecture, RS485 networking, and licensing options (Standard, Professional, Client). Benefits such as reduced commissioning time, integrated plant monitoring, and data export for quality control are highlighted.
| Maximum controllers per RS485 network | 128 |
|---|---|
| Supported controller ranges | 33/93/9400 and 9500P |
OPC is an interfacing standard based on Microsoft’s OLE/DCOM technology.
It can connect to a single RS485 network of up to 128 controllers.
CALgrafix works with CAL’s 33/93/9400 and 9500P temperature and process controllers.
