Profibus PA Vs Foundation FieldBus

Scorpio31

Hi,

If i have to use siemens transmitter( level) and Master PLC is S-7 315-2DP which protocol should i go for level transmitter, profibus PA or foundation field bus.. or simple 4-20 directly to analog card?

Hi,
you can select all of them. It depends on your project requirements.
Could you please give us more information about your project in following items?
1. The number of analog inputs and outputs.
2. about explosion environment
3. What is your purpose of using PA or F.Fieldbus? (Reduce wiring or remote calibration facilities)

Regards,
MRG

Hi,

Refer reply as under:-

1) The number of analog inputs and outputs.
Analog 50( approx)such transmitters, DI/ DO, around 500nos.

2. about explosion environment
NO

3. What is your purpose of using PA or F.Fieldbus? (Reduce wiring or remote calibration facilities)
Of course reduction in cabling and PID.

Hi,

thanks for your reply....

Among Profibus PA and FFB, which should be used?

Foundation Fieldbus is an all-digital, serial, two-way communications system that serves as the base-level network in a plant or factory automation environment. It is an open architecture, developed and administered by the Fieldbus Foundation.

It's targeted for applications using basic and advanced regulatory control, and for much of the discrete control associated with those functions. Foundation fieldbus technology is mostly used in process industries, but nowadays it is being implemented in powerplants also.

FOUNDATION fieldbus was originally intended as a replacement for the 4-20 mA standard, and today it coexists alongside other technologies such as Modbus, Profibus, and Industrial Ethernet. FOUNDATION fieldbus today enjoys a growing installed base in many heavy process applications such as refining, petrochemicals, power generation, and even food and beverage, pharmaceuticals, and nuclear applications.

A typical fieldbus segment consists of the following components.

• H1 - fieldbus interface card
• FPS - Fieldbus Power Supply and Signal Conditioner
• PS - Bulk power (Vdc) to Fieldbus Power Supply
• T - Terminator
• And fieldbus devices, (e.g. transmitters, transducers, etc.)
