Farhan Hi vajont Can you post the Pin details of H51q-HRS ? Normally the RS485 Connection requires you to connect only R(A) and R(b) + Shield ( and Ground - if available ). Pl see the typical connection details. You don't need to connect T(A) , T(B) if you are using RS485 2-Wire conection. Pl seet attachment for a typical RS485 2-Wire connection for CP341 Hope this helps Cheers Navnag AttachmentCP341_RS485_2Wire.pdf (920 Downloads) |

Hi vajont You should be able to test communication with CP341 using any RS232 to RS485 convertor. Use a Modbus Master / Slave Simulator on your PC for testing : http://www.modbustools.com/index.asp Please check that you have made the correct settings in the CP-341 hardware configuration ( After installing CP-PTP software ) and the Blocks in STEP7 software have been called properly. If you can upload a copy of your program then I can have a look at it . Hope this helps Cheers Navnag |
