to iec 61784-1, cp 3/2. this part of iec 61326 covers only the field-bus interface of the equipment.note the other functions of the equipment are covered by other parts of the iec 61326 series.this part of iec 61326 refers only to field devices intended for use in process control and process measuring.for interface operation and the interface parameters, this part of iec 61326 is in accordance with iec 61784-1, cp 3/2. that standard specifies a set of protocol specific communication profiles based on the iec 61158 series.the manufacturer specifies the environment for which the product is

except as follows:addition:5.2.101test configurationin order to assign any malfunction of the communication during the emc test to the eut, the configuration of field devices with interfaces according to iec 61784-1, cp 3/2, shall be limited to the operation of one master and one slave (eut) during emc type tests.for the slave, auxiliary connections for power supply or signalling are possible.the slave is connected via a three-port field distributor with the signal coupler. the signal coupler is connected to the automation system.a standardized field-bus terminator is attached at the third port of the field distributor.the components eut, signal coupler, field distributor and terminator are connected by means of a standardized field-bus cable.1 other parts are under consideration.licensed copy: institute of technology tallaght, institute of technology, wed aug 15 19:50:37 gmt+00:00 2007, uncontrolled copy, (c) bsithe shield shall be connected at any individual component by a low-impedance grounding strip (connection between the shield and the case with a large surface).the individual cable lengths l1, l2, l3 originate from a practice-adjusted setup, such as the one given in figure 101.the cable length l4 should be in the range of 8 m, in the case where the respective basic standards do not specify other lengths. the cable installation shall be in accordance with the appropriate basic standard.the connection of the shield at the shield grounding point may be produced by partially removing the isolation of the cable shield and fixing the cable shield with a metal clamp or by means of conductive leading-in conductors such as a metallic cable gland at the ground plane or at the shielding metal wall, respectively.the location and execution of the shield grounding point depends on the given test facility; for example, by use of an anechoic chamber or a shielded cabin, it is the metal wall penetration; and with tests on tables with ground plane the shield grounding point is on the ground plane.5.2.102connection linea standard bus cable type a shall be used as the communication line (see 11.8.2 ofiec 61158-2:2003). the cable lengths l1 to l3 are given in figure 101 and l4 is described in.2.103connections at the eutthe grounding of the eut and the shield connections shall be in accordance with the manufacturers specification.5.2.104field-bus network for emc testthe field-bus network includes the terminator of the bus line, a field distributor, a signal coupler, the automation system and the eut.the evaluation and conditioning of the data in the signal coupler and the automation system is not the object of this part of iec 61326.the field distributor and the bus terminator are passive components

operational conditionsthe operating conditions describe the software settings at the field device (eut) and at the automation system. the master connected to the signal coupler is set as master class 1, the eut as slave.the cyclic operating mode shall be used.the parameter retry limit shall be set to 2 at the master. this means that, after three consecutive transmission errors (bus-line break down or slave not working), the master (automation system) sets the status to 0.the general bus parameters for the cyclic data exchange in table 84 of iec 61158-3:2003 shall be taken into account.5.3.102statusthe field bus controller, in conjunction with the automation system, monitors the received data of the eut. the received data is of the data type qualifiedfloat32 or qualifiedunsigned8 as defined in 2 or 3 of iec 61158-5. those data types are of the format structure and have a field named status.for the automation system and the test evaluation, the quality in the status is significant.in the case of received data, only four qualities can appear (extract taken from .2.2 ofiec 61158-6):good (cascade)means that the status is in the range between 192 and 255good (non cascade)means that the status is in the range between 128 and 191uncertainmeans that the status is in the range between 64 and 127badmeans that the status is in the range between 0 and 63the eut shall preferably be configured so that the value of the status is 128.other values for the status are allowed if they enable the evaluation of the function of the eut. however, values of the status indicating a disturbed communication shall be avoided. if a status value deviating from 128 is chosen, the reasons for this decision shall be given in the test report.5.3.103monitoringa) the status shall be monitored.b) the measuring value shall be monitored.if the allowed tolerances are not specified in an appropriate part of iec 61326, the values specified by the manufacturer may be
