Hi, I am getting error 16#80C8 at the master block. Please advise on what could cause this. I have attached the sample program here. ------------------------------------------------------------------------------------------ Attachment47756141_Sample_project_for_STEP_7_TIA_Portal_V15.zip (210 Downloads) |

Hi, Attached is the photo of the VSD that is being used now & the wiring (RS 485) therefore using mode "0". Besides, termination resistor also was used on both ends (120 ohm resistor at the VSD end & 220ohm ohm resistor at PLC COM module). Also tried with another cable (without resistor on both ends (but still getting error 16#80C8). Already check the baud rate, parity but still getting the same error code. How can overcome this?
