1.1 Importante
Leggere attentamente queste istruzioni prima dell’installazione e prima
dell’uso e seguire tutte le avvertenze per l’installazione e per il collega-
mento elettrico; conservare queste istruzioni con il controllore per con-
sultazioni future.
Il controllore deve essere smaltito secondo le normative
locali in merito alla raccolta delle apparecchiature elettriche
ed elettroniche.
2 INTRODUZIONE
2.1 Introduzione
c-pro 3 hecto+ è una famiglia di controllori programmabili.
La famiglia è disponibile nella versione:
• con visualizzatore grafico LCD monocolore (nero con retroilluminazione
a LED bianchi) da 128 x 64 pixel e con tastiera in gomma siliconica a 6
tasti (con funzioni predefinite) integrati nel controllore, in seguito de-
nominate anche versioni built-in
• cieca (utilizzabile per esempio con un terminale utente come Vgraph
o Vtouch), in seguito denominate anche versioni cieche.
I controllori dispongono di:
- orologio
- buzzer di allarme (non disponibile nelle versioni cieche)
- 4 ingressi analogici di cui 3 configurabili via parametro di configura-
zione per sonde PTC / NTC / Pt 1000 / trasduttori 0-20 mA / 4-20 mA
/ 0-5 V raziometrici / 0-10 V e 1 per sonde NTC
- 5 ingressi digitali optoisolati a 24 VAC / DC
- 3 uscite analogiche di cui 1 non optoisolata di tipo PWM e 2 non
optoisolate configurabili via parametro di configurazione per segnale
di tipo 0-20 mA / 4-20 mA / 0-10 V
- 6 uscite digitali (relè elettromeccanici) di cui 5 da 3 A res. @ 250 VAC di
tipo SPST e 1 da 5 A res. @ 250 VAC di tipo SPDT
- 3 porte di comunicazione non optoisolate di cui 1 di tipo CAN con
protocollo di comunicazione CANbus, 1 di tipo RS-485 con protocollo
di comunicazione Modbus master / slave (configurabile via software
applicativo) e 1 per la programmazione e il debug.
Attraverso l’espansione di I/O c-pro 3 EXP hecto o c-pro 3 EXP hecto+
è possibile incrementare il numero di ingressi e di uscite.
Attraverso l’ambiente di sviluppo UNI-PRO 3 (da ordinare separatamente)
è possibile realizzare il software applicativo e attraverso il kit di program-
mazione EVIF20TUXI (da ordinare separatamente) è invece possibile pro-
grammare il controllore.
I dispositivi si presentano in contenitore 4 moduli DIN.
L'installazione è prevista in un quadro elettrico, su guida DIN.
Attraverso la chiave di programmazione EVKEY10 (da ordinare
separatamente) è possibile eseguire l'upload e il download dei parame-
tri di configurazione.
