SINEAX DME 401 with RS 485 interface Programmable multi-transducer

Transcription

1 withot anaoge otpts, transfer of data ia a MODBS interface Appication SIEA DME 401 (Fig. 1) is a programmabe transdcer with a RS 485 bs interface (MODBS ). It sperises seera ariabes of an eectrica power system simtaneosy. The RS 485 interface enabes the ser to determine the nmber of ariabes to be sperised (p to the maximm aaiabe). The ees of a interna conters that hae been configred (max. 4) can aso iewed. Proision is made for programming the SIEA DME 401 ia the bs. A standard EIA 485 interface can be sed. The transdcers are aso eqipped with an RS 3 seria interface to which a PC with the corresponding software can be connected for programming or accessing and execting sef anciary fnctions. This interface is needed for bs operation to configre the deice address, the Bad rate and possiby increasing the teegram waiting time (if the master is too sow) defined in the MODBS protoco. The sa methods of connection, the types of measred ariabes, their ratings and the type of interna energy/metering are the main parameters that can be programmed. The anciary fnctions incde a power system chec and a faciity for printing namepates. The transdcer ffis a the essentia reqirements and regations concerning eectromagnetic compatibiity (EMC) and safety (IEC 1010 resp. E ). It was deeoped and is manfactred and tested in strict accordance with the qaity assrance standard ISO Featres / Benefits Simtaneos measrement of seera ariabes of a heay-crrent power system / F sperision of an asymmetricay oaded for-wire power system, rated crrent 1 to 6 A, rated otage 57 to 400 (phaseto-netra) or 100 to 693 (phase-to-phase) Measred ariabes Otpt Types Crrent, otage (rms), actie/reactie/apparent power cosϕ, sinϕ, power factor RMS ae of the crrent with wire setting range (bimeta measring fnction) Sae pointer fnction for the measrement of the RMS ae IB Freqency Aerage ae of the crrents with sign of the actie power (power system ony) Withot anaoge otpts, with bs interface RS 485 (MODBS) 4 anaoge otpts and bs interface RS 485 (MODBS) see Data Sheet DME e anaoge otpts and 4 digita otpts or 4 anaoge otpts and digita otpts see Data Sheet DME 44/44-1 e Data bs O see Data Sheet DME e PROFIBS DP see Data Sheet DME e DME 401 DME 440 DME 44 DME 44 DME 400 DME 406 Fig. 1.

12 Connecting deices to the bs The RS 485 interface of the DME 401 is gaanicay isoated from a other circits. For an optima data transmission the deices are connected ia a 3-wire cabe, consisting of a twisted pair cabe (for data ines) and a shied. There is no termination reqired. A shied both preents the coping of externa noise to the bs and imits emissions from the bs. The shied mst be connected to soid grond. Yo can connect p to 3 members to the bs (incding master). Basicay deices of different manfactrers can be connected to the bs, if they se the standard MODBS protoco. Deices withot gaanicay isoated bs interface are not aowed to be connected to the shied. The optima topoogy for the bs is the daisy chain connection from node 1 to node to node n. The bs mst form a singe continos path, and the nodes in the midde of the bs mst hae short stbs. onger stbs wod hae a negatie impact on signa qaity (refection at the end). A star or een ring topoogy is not aowed. Important: Each deice connected to the bs mst hae a niqe address A deices mst be adjsted to the same badrate. Dimensioned drawings , Fig. 5.

Interface conerters RS3 RS485 or RS485 interface cards often hae a bit-in termination networ which can be connected to the bs. The second impedance then can be connected directy between the bs terminas of the deice far most. Fig. 4 shows the connection of transdcers DME 401 to the MODBS. The RS 485 interface can be reaized by means of PC bit-in interface cards or interface conerters. Both is shown sing i.e. the interfaces and 8601 of W & T (Wiesemann & Theis GmbH).
