19、ELECTRICAL EQUIPMENT FOR MEASUREMENT, CONTROL AND LABORATORY USE EMC REQUIREMENTS Part 2-5: Particular requirements Test configurations, operational conditions and performance criteria for field devices with interfaces according to IEC 61784-1, CP 3/2 1 Scope In addition to the requirements of IEC 6

20、1326-1, this part of IEC 61326 treats the particular features for EMC testing of field devices with interfaces according 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 IE

21、C 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 co

22、mmunication profiles based on the IEC 61158 series. The manufacturer specifies the environment for which the product is intended to be used and/or selects the appropriate test level specifications of IEC 61326-1. 2 Normative references The following referenced documents are indispensable for the app

23、lication of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. Clause 2 of IEC 61326-1 applies, except as follows: Addition: IEC 61326-1:2005, Electrical equipment for measurem

28、1 applies. 4 General Clause 4 of IEC 61326-1 applies. 5 EMC test plan 5.1 General Subclause 5.1 of IEC 61326-1 applies. 5.2 Configuration of EUT during testing Subclause 5.2 of IEC 61326-1 is applicable, except as follows: Addition: 5.2.101 Test configuration In order to assign any malfunction of th

29、e 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 poss

30、ible. 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 ter

31、minator are connected by means of a standardized field-bus cable. 1Other parts are under consideration. 5 EN 61326-2-5:2006 The 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 c

32、able 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

33、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 t

34、he 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

35、is on the ground plane. 5.2.102 Connection line A standard bus cable type A shall be used as the communication line (see 11.8.2 of IEC 61158-2:2003). The cable lengths L1 to L3 are given in Figure 101 and L4 is described in 5.2.101. 5.2.103 Connections at the EUT The grounding of the EUT and the shi

36、eld connections shall be in accordance with the manufacturers specification. 5.2.104 Field-bus network for EMC test The 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

37、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 only.

39、g 7 EN 61326-2-5:2006 5.3 Operation conditions of EUT during testing Subclause 5.3 of IEC 61326-1 is applicable, except as follows: Addition: 5.3.101 Operational conditions The operating conditions describe the software settings at the field device (EUT) and at the automation system. The master conn

40、ected 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 (autom

41、ation 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. 5.3.102 Status The field bus controller, in conjunction with the automation system, monitors the received data of the EUT. The received data is o

42、f the data type QualifiedFloat32 or QualifiedUnsigned8 as defined in 5.3.3.12 or 5.3.3.13 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 d

43、ata, only four qualities can appear (extract taken from 13.1.1.3.2.2 of IEC 61158-6): “Good (Cascade)“ means that the Status is in the range between 192 and 255 “Good (Non Cascade)“ means that the Status is in the range between 128 and 191 “Uncertain“ means that the Status is in the range between 64

44、 and 127 “Bad“ means that the Status is in the range between 0 and 63 The 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

45、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. 5.3.103 Monitoring a) The Status shall be monitored. b) The measuring value shall be monitored. If the allowed tolerances are not specified in an appropria

46、te part of IEC 61326, the values specified by the manufacturer may be used. EN 61326-2-5:2006 8 5.4 Specification of performance criteria Subclause 5.4 of IEC 61326-1 applies. 5.5 Test description Subclause 5.5 of IEC 61326-1 applies. 6 Immunity requirements 6.1 Conditions during the tests Subclause

47、 6.1 of IEC 61326-1 applies. 6.2 Immunity test requirements Subclause 6.2 of IEC 61326-1 applies. 6.3 Random aspects Subclause 6.3 of IEC 61326-1 applies. 6.4 Performance criteria Subclause 6.4 of IEC 61326-1 applies. In addition, the Status shall be monitored. Performance criteria A: The Status val

48、ue chosen according to 5.3.102 shall be unchanged during and after the test. Performance criteria B: The Status value during the test may deviate from that chosen according to 5.3.102. The Status value after the test shall remain unchanged from that chosen according to 5.3.102. Performance criteria

49、C: The Status value during and after test may deviate from that chosen according to 5.3.102. 7 Emission requirements Clause 7 of IEC 61326-1 applies. 8 Test results and test report Clause 8 of IEC 61326-1 applies. 9 Instructions for use Clause 9 of IEC 61326-1 applies. _ 9 EN 61326-2-5:2006 Annex ZA (normative) Normative references to international publications with their corresponding European publications The following referenced documents are in
