AC500 / digital module - Missed signals on codesys

Buonasera.Avrei una problematica con l'acquisizione di alcuni segnali digitali.La CPU è una PM590 Eth.Su una DI524, a valle di un modulo CS31, vengono acquisiti correttamente gli stati di alcuni devices (relativi led di stato accesi).Il problema è che su CoDeSys, in running, per quella stessa scheda gli stati sono tutti in 'false'.Occorre staccare dalla basetta il modulo digitale e ricollegarlo ed a quel punto, su CoDeSys, vengono acquisiti correttamente le segnalazioni.Accade principalmente quando il PLC viene disalimentato (il boot project è stato fatto).Quale potrebbe essere la problematica?Grazie per ogni eventuale risposta.Cordiali saluti

Salve Mario

potrebbe trattarsi di un problema relativo al modulo oppure un falso contatto.

Se hai altri moduli DI524 nel tua HW, prova a spostare la scheda di ingressi da una posizione a un'altra e verificare che il problema si ripresenti.

Questo problema c'è sempre stato oppure si è verificato solo di recente?

Per la maggiore comprensione del tuo problema da parte di tutti gli utenti, ti invito a scrivere nel forum in inglese, lingua ufficiale.

Hi Mario

This may be a problem with the module or a fake contact.
If you have other DI524 modules in your HW, try to move the input board from one location to another and check that the problem is reoccurring.

Has this problem always been or has just happened recently?

For greater understanding of your problem by all users, I invite you to write in the forum in English, the official language.

Hope this help you
