Major DCS Vendors Approve Pepperl+Fuchs FF Modular I/O
FOUNDATION Fieldbus receives digital and analog signals
Foundation Fieldbus receives digital and analog signals
Proven in use system
By adding a FOUNDATION Fieldbus gateway to the proven Remote I/O you are able to use the known reliable hardware to make use of the standard FOUNDATION Fieldbus Multi-Function Blocks. So, for the very first time there are modular FOUNDATION Fieldbus I/O modules to interface with all kinds of traditional signals and high-power instruments. They also make better use of the 31.25 kbps data transmission rate and help to cut costs.
FF modular I/O architecture—FF digital or analog inputs and outputs
At the same time they are highly compact with up to 40 digital inputs or outputs or 20 analog inputs or outputs or a combination thereof.
FF Modular I/O Architecture
The FF Modular I/O can be regarded as any other individual FF device with several variables. The FF Modular I/O is integrated into the Host system by means of DDs (device description) and CFF (configuration file) files. This ensures full system integration and easy engineering access.
Physically it behaves in the same way as a standard FF node. Additional IS barriers are not required as it can be directly connected to the fieldbus trunk. The legacy devices are connected to the I/O modules using intrinsically safe loops in the same way as in the conventional isolated barrier approach. Even NON IS signals can be accommodated side by side with intrinsically safe loops.
That way all non FOUNDATION Fieldbus signals can be brought to the fieldbus without having to replace existing equipment. This saves costs on a major scale since it is no longer necessary to buy all new field devices to bring them in line with fieldbus when brown field plants are modernized.
The installed base of pressure and differential pressure transmitters can stay in place as can the motorized valves, positioners, and solenoids. In hazardous area applications these field devices are connected to the FF Modular I/O using the traditional form of intrinsic safety wiring to FISCO or to the Entity concept.
FF Modular I/O represents a bridge between conventional digital and analog signals and the most modern FOUNDATION Fieldbus technology. That way it completes the range of FOUNDATION Fieldbus devices.
