1. NOTE The node address cannot be changed when the module is operating but is detected only when the equipment is powered on 4 2 TERMINATION The end nodes of a Profibus DP network must have terminations avoiding to interfere with the bus line To do so the Profibus DP module is equipped with a termination switch For the first or the last converter in the network the switch must be ON otherwise for intermediate converters it must be OFF N B If a connector with an external termination is used the switch must be OFF 6 7 DCREG 16B0221B3 2 Interface DCREG via Profibus DP ELETTRONICASANTERNO 4 3 INDICATIONS The module is provided with four LEDs installed on its front part and with one LED assembled on the control board and which is used for debugging operations 4 3 1 Front LEDs 1 Not used 2 On Line 3 Off Line 4 Fieldbus diagnostics The LED functions are described in the table below LED 2 Indicates that the converter is On Line on the Fieldbus On Line Green the module is On Line data exchange is allowed Off the module is On Line 3 Indicates that the converter is Off Line on the Fieldbus Off Line Red The module is Off Line no data exchanged allowed Off The module is not Off Line 4 Indicates that errors occurred on the Fieldbus side Fieldbus Flashing red at 1 Hz Error while configurating the message length set while initializing the diagnostics module does not match with the me2. e 16B0301B3 DCREG MODBUS RTU USER GUIDE DCREG INTERFACE VIA MODBUS RTU Agg 03 05 04 R 00 7 Versione D3 09 lta Iano e presente manuale costituisce parte integrante ed essenziale del prodotto Leggere attentamente le avvertenze contenute in esso in quanto forniscono importanti indicazioni riguardanti la sicurezza d uso e di manutenzione e Questa macchina dovr essere destinata al solo uso per il quale stata espressamente concepita Ogni altro uso da considerarsi improprio e quindi pericoloso Il Costruttore non pu essere considerato responsabile per eventuali danni causati da usi impropri erronei ed irragionevoli e L Elettronica Santerno si ritiene responsabile della macchina nella sua configurazione originale e Qualsiasi intervento che alteri la struttura o il ciclo di funzionamento della macchina deve essere eseguito od autorizzato dall Ufficio Tecnico della Elettronica Santerno e L Elettronica Santerno non si ritiene responsabile delle conseguenze derivate dall utilizzo di ricambi non originali L Elettronica Santerno si riserva di apportare eventuali modifiche tecniche sul presente manuale e sulla macchina senza obbligo di preavviso Qualora vengano rilevati errori tipografici o di altro genere le correzioni saranno incluse nelle nuove versioni del manuale e L Elettronica Santerno si ritiene responsabile delle informazioni riportate nella versione originale del manuale in lingua Italiana Propriet
