com mod mast
i am connecting the multi function meter through RS485 cabel in PLC on board port COM1 ,and i read the meters values via modscan.But if i read the data in PLC logic am not getting the value it's showing 8211(timeout error). i used COM_MOD_MAST block with Blink function.And so i add the com1_modbus in automation builder, changed the baudrate,parity,data and stop bits as per the meter registerd.How to solve this and get the meters value by using this block.

If you can read values though the Modscan, you can easily red with Com_Mod_Mast.
By the way Com_Mod_Mast depends various parameters like Correct serial Port Configuration, Correct Com Port, Correct Cable Polarity etc. Are you sure about these parameters?
Without your configuration or code we can not find out the problem.
