Hi everyone I am facing difficulties with modbus masterconnection between S7- 200 and an external GC (which sends data on the modbus lines in 32 bit-floating point formate as a slave . Some data is received after using Modbus comunication blocks ( MBUS_CTRL ,MBUS_MSG ) The problem appears when it comes to reading these values, I am not sure how I should read these 32 bit values when Modbus sends them in 8 Bit packages .(stored in VB0 ~ VB8 ) . I am now using a code identical to the one in chaspter 12 of siemens S7200 manual for testing but the received values do not make sense . Has anyone had this problem before or can give me an advice? I attach the screenshots of the code and project . Regards Attachmentproject.zip (79 Downloads) |
