The shielded cable types A or B are approved to use in combination with TF02 / TF202.The optimum electromagnetic compatibility of TF02 / TF202 is only guaranteed, if shielded cables are used forthe wiring of the sensor connection.The correct terminal for the cable shield connection is describe in the chapter 3.1 (TF02 / TF202 installationsites).GroundingThe metallic connection head AGL / AGLF / AGS / AGSF, that are offered for the TF02 / TF202 have to connectdirectly to ground potential. Use for this connection Copper cable with a diameter at least of 4mm².EMCThe optimum electromagnetic compatibility of systems is only guaranteed if system components and in particularlines are shielded and the shielding provides the most complete coverage possible.3.4 Maintenance, repair, trouble-shootingThe TF02 / TF202 is fully operational immediately after switching on the fieldbus power supply.The TF02 / TF202 is virtually maintenance-free.Observe the warnings attached to the housing (externally and on the internal cover).16 Temperature Transmitters TF02/TF02-Ex (head mounted) and TF202/TF202-Ex (field mounted) 42/11-51 EN
Fieldbus Communication4 Fieldbus Communication4.1 Block structureA FF device consists of several function blocks. Most of these blocks are specified by the Fieldbus Foundation,as a Transducer Block or Resource Block for example. The TF02 consists of the following blocks:• Resource Block• Transducer Block• AI Block I•AI Block IIThe Resource Block describes the device itself with all communication relevant data. The Transducer Block isthe interface to the sensor and therefore its parameters control the measurement function of the TF02. The twoAI Blocks scale the values in a proper way to provide them to function blocks as controllers of other FF deviceslike valve positioners.Sensor 1; (T1)Value_1 (T1)AI Block 1AI 1out value sensor 1+ StatusTransducer BlockTBValue_2 (T2)AI Block 2AI 2out value sensor 2+ StatusSensor 2; (T2)Resource BlockReference junctionPt100by requestonly readby requestread/writeFig. 4-1Block structure of the TF024.2 Resource Block4.2.1 OverviewThis block contains data that is specific to the hardware that is associated with the resource. All data is modeledas Contained, so there are no links to this block. The data is not processed in the way that a function block processesdata, so there is no function schematic. This parameter set is intended to be the minimum required forthe Function Block Application associated with the resource in which it resides. Some parameters that could bein the set, like calibration data and ambient temperature, are more appropriately parts of their respective transducerblocks.4.2.2 DescriptionThe block data are classified into two groups. Operation data affect or reflect the operation of the Function BlockApplication within its resource. Other data does not. Each group is further divided into static and dynamic data.Normally the Engineering Tool would read or write parameters of the Resource Block automatically. Mostly thedata is entered offline or is calculated by the environment. With the parameter TAG_DESC the device is referencedin the system.42/11-51 EN Temperature Transmitters TF02/TF02-Ex (head mounted) and TF202/TF202-Ex (field mounted) 17
