2600T Series Pressure transmitters | OI/266/FF-EN Rev. B 296 Device introduction6. Device introduction6.1 Fieldbus Foundation communication protocolFoundation Fieldbus™ is an all-digital, serial, two-waycommunication system that serves as a Local Area Network(LAN) for factory/plant instrumentation and control devices.Important. Further information on FOUNDATION Fieldbus can befound from the Fieldbus Foundation organization website www.fieldbus.org , from the ABB website www.abb.com/fieldbus and/orfrom standards IEC 61158, IEC 61784, EN 50170/DIN 19245 andEN 50020 (FISCO model)6.2 Feature overviewThe 2600T-266 PdP Foundation Fieldbus is compliant to thecommunication Protocol FOUNDATION™ Fieldbus specificationversion 1.8. The 2600T-266 PdP FF is a Link Master Deviceimplementing the following Blocks:— 1 Enhanced Resource Block— 2 Enhanced Analog Input Function Blocks— 1 Standard Analog Input Function Block— 1 Enhanced PID Function Block— 1 Standard Arithmetic Function Block— 1 Standard Integrator Function Block— 1 Standard Input Selector Function Block— 1 Standard Control Selector Function Block— 1 Standard Signal Characterizer Function Block— 1 Enhanced Pressure with Calibration Transducer Block— 1 Custom HMI Transducer Block— 1 Custom Advanced Diagnostic Transducer Block with“Plugged Input Line Detection” algorithm.6.3 Registration detailsAll the Registration details are available from the FieldbusFoundation webpage at the following link:http://www.fieldbus.org/index.php?option=com_mtree&task=viewlink&link_id=1565&ffbstatus=Registered&Itemid=3246.4 FF device structureThe Foundation Fieldbus devices can be divided into two partsunder the point of view of technical competence who must takecare of its configuration and use.— The Device Application Process (DAP) is device specificand stays with the device wherever it is used.— The Control Application Process (CAP) is configured forthe specific plant location and may be spread overmultiple devices.Communication between the DAP and CAP takes place usingchannels. Each I/O function block in the CAP has exclusive useof exactly one channel. A channel may be bi-directional and itmay have multiple values.6.5 Device Application Process (DAP)The DAP is used primarily by the instrumentation technician ormaintenance personnel for configuring I/O when the instrumentis going to be installed in the plant and/or during maintenanceoperations and for this reason mainly focused on the ResourceBlock and Transducer Blocks of the device.6.6 Control Application Process (CAP)The CAP is used by the control engineer for configuring the plantcontrol strategy and for this reason mainly focused on theFunction Blocks of the device.Important. For convenience, all the device parameters mentioned inthis document are written with the prefix indicating the block intowhere they are mapped:– RB_ = Resource Block– PRTB_ = Pressure Transducer Block– ADTB_ = Advanced Diagnostic Transducer Block– HMI_ = HMI Transducer Block– AIx _ = Analog Input Function Blocks where the x is thenumber of the AI (1, 2, 3)Figure 35: Device function block applicationDeviceVFDAnalogInputBlockDigitalInputBlockChannelChannelLinkLinkCAPInstrumentation Technician’s Domain (DAP)StrumentistaControl Engineer’s Domain (CAP)TransducerBlock(s)ResourceBlock(Only 1)DAPPhysicalI/OPIDBlockLinkLinkImportant.
