An interface solution to Profibus

January 2002 Operator Interfaces, Switches & Relays

Devices with conventional digital and analog interfaces in the chemical and process engineering industries can be connected to Profibus PA via Smar Profibus PA 303 Converters, using the FI303, IF303 and FP303. These products are the Profibus PA to Current, Current to Profibus PA and Profibus PA to pneumatic signal converter, respectively. Also they can be connected to Profibus DP via distributed I/O systems using PLCs or modules I/O. This permits the migration of an existing field device interface to Profibus.

Smar Series 303 of Profibus PA devices

Smar range of Profibus devices includes:

* LD 303 full range of DP, gauge, pressure and level transmitters.

* TT 303 temperature transmitters.

* FY 303 valve positioner.

* FP 303 Profibus to pressure converter.

* IF 303 current to Profibus PA converter.

* FI 303 Profibus to current converter.

Configuration of Smar Series 303 devices

The Series 303 from Smar uses the Simatic PDM (process device manager) as a configurator and parameterisation tool and it is a totally integrated and manufacturer-independent tool for configuring, parameterisation, commissioning and diagnosis of intelligent process field devices.

The Series 303 can be configured by other configurator tools compatible with Profibus PA - and this family of devices may be integrated with an HMI tool if the tool is open, manufacturer-independent and interoperable with Profibus PA technology. Diagnostics and start-up is performed from a PC or programming device connected to the Profibus-DP. The Simatic PDM configuring tool can be used on a PC for the following tasks:

* Parameterisation and commissioning.

* Network configuration and project management.

* Uniform operation of all process devices.

* Network and instrument diagnosis during breakdown or start-up (phase failure, ...).

* Extended diagnostic functions (device-specific).

* Maintenance.

* Calibration and other device methods.

* Asset management.

* Life cycle management of devices and TAGs.

* Comparison and checking of parameter values.

* Logging of user activities.

* User administration.

* Views of process devices.

* Network view.

* Plant view.

* Offline parameterisation.

* Status of parameter values.
