Sir, please Find PLC Program. kIndly Retrive it. there is no any other Setting i My slave Device Except Baudrate and Slave Address. As per Slave Device catalogue, Parity is None, Baudrate 9600, Slave address 1, data bit 8 please highlight my mistake in Program if any or suggest how i can resolve error 16#0830 AttachmentModbus_t.zip (199 Downloads) |

Sir, there is no Diagnostics in Slave Device to Access. We can Change Baudrate and Slave No from Keypad Only. We can easly view Slave Parameter through Modscan. Here Modbus related information from Slave Device. AttachmentPages from POWERPRO_Manual-2.pdf (197 Downloads) |

So you can get data off the slave device using modscan. This means that the slave device must be fine. I assume then that you have some form of RS485 to RS232 convertor? As the PC you are running modscan on is unlikely to have a RS485 port as standard. If that is so we can use this to do some protocol data analysis using a serial port monitor. This is available as a free download here. Capture some data packets with the S7 comunicating to the slave device and upload the data here for I me to look at. |
Programming today is the race between software engineers building bigger and better idiot proof programs, and the universe producing bigger and better idiots. |
