Communication Profile Family 1 (commonly known as FOUNDATION? Fieldbus1) defines communication profiles based on IEC 61158-2@ Type 1@ IEC 61158-3-1@ IEC 61158-4-1@ IEC 61158-5-5@ IEC 61158-5-9@ IEC 61158-6-5@ and IEC 61158-6-9. The basic profiles CP 1/1 (FF H1) and CP 1/2 (FF HSE) are defined in IEC 61784-1. This part of ISA-62453 provides information for integrating the FOUNDATION? Fieldbus (FF) protocol into the FDT standard (ISA-62453-2 [103.00.02]). The standard describes communication definitions@ protocol specific extensions and the means for block (e.g. transducer@ resource or funct ion blocks) representation. The new protocol specific definitions are based on FF-specifications for H1 and HSE protocols. Furthermore@ the definitions contain information that is needed by systems to configure FF devices. The scope is limited to FOUNDATION? Fieldbus device and system specific definitions.
