Protocollo Siemens S7-200 Porta Seriale

[SimoneBaldini]

Visto che non si hanno le specifiche e visto che si puo' banalmente monitorare la porta seriale (spiare cosa si scrive sopra) puo' essere utile la cosa per carpire il protocollo?

questo è quanto viene trasmesso e ricevuto dalla porta nella fasce d'apertura dal programma PC_SIMU (spagnolo):
