Protea Industrial Control says that connection to PLCs and PC supervisory packages is made easy with the 2408f and 2404f Profibus-DP controllers. Available in 1/8 DIN and 1/4 DIN panel sizes, they provide independent front-end control of temperature and other process variables without any compromise in performance.
Unlike other products, the design is not a gateway but uses a direct connection to the microprocessor bus of the controller, thereby ensuring efficient communications.
A Windows "set-up Wizard" sets up the controller parameters that are mapped into the PLC registers. This allows the ladder logic or control program to read and write to the controller as though it were an internally fitted module.
The controllers offer stable control with a range of control options. One-shot and continuously adaptive tuning optimises control performance without the need for specialist knowledge or training. A modular build accommodates a range of plug-in I/O modules.
Features include:
* Up to four internally stored setpoint programs.
* Analog retransmission.
* Remote setpoint.
*Two PV inputs for differential, max, min or transfer control.
