HI.when am try to  communication between s7-1200 plc to arduino uno via profinet there is some status is always busy can you please send me that steps .

automatizzando

I hope to do something pleasant.

I do not know if it can be of interest, but recently was released a library for Arduino that allows communication with any PLC siemens. Logo understood.

• S7 200/300/400/1200/1500 and LOGO 0BA7 are managed.
• Full PLC memory access (E/A/M/DB/T/Z)
• Helper functions for data conversion (Big Endian --> Little endian)
• PDU independence : large data transfer in a single call (limited only on the available memory)
• Three memory models for footprint optimization.
• Uses standard Arduino Ethernet library i.e. it can coexist with other clients/servers in the same sketch.
• 3 ms to read one PDU (240 bytes) into the internal buffer.
• Detailed documentation.

Spero di fare una cosa gradita.

Non so se la cosa può interessare, ma di recente è stata rilasciata una libreria per arduino che permette la comunicazione con qualunque PLC siemens. Logo compreso.

• S7 200/300/400/1200/1500 e LOGO 0BA7 sono gestiti.
• Accesso alla memoria piena PLC (E / A / M / DB / T / Z)
• Le funzioni di supporto per la conversione di dati (Big Endian -> Little endian)
• Indipendenza PDU: grande trasferimento di dati in una singola chiamata (limitato solo dalla memoria disponibile)
• Tre modelli di memoria per l'ottimizzazione footprint.
• Utilizza biblioteca Arduino Ethernet standard cioè può coesistere con altri client / server nello stesso schizzo.
• 3 ms per leggere un PDU (240 byte) nel buffer interno.
• Documentazione dettagliata.

Split from Arduino and S7 1200. Two devices that communicate in profilnet.

Hello MADHUSU,

is your communication meanwhile running?
If not, please share some more information.
Are there any entries within the diagnostic buffer of the CPU?
Is the connection established?
Which communication blockes are you using?

Good luck
Sabine

New question published by zakazikoyo87 is split to a separate thread with the subject How can send instruction to open the electrovalve from the s7 1200 to arduino when the soil is dry?.
