Simuzer Posts: 5 Rating: (0)	Thanks a lot. PAC3100 setting values; Address: 20 Baudrate: 19200 Format: 8N1 Response Time: 0ms Wago settings values; Com_Baudrate: BAUD_19200 Com_Parity: PARITY_NO Com_Port: 16#02 Com_Stopbits: STOPBITS_1 Com_Bytesize: BS_8 Com_Flow_Control: HALFDUPLEX Query.StartAddress: 1 (i am not sure, this is "offset" value ?) Query.FunctionCode: 3 Query.SlaveAddress: 20 Query.Quantity: 3 According to all these settings, yellow and green LEDs are blinking. And; MB_Error function says No Error. I think the connection is correct, but I can not read the valuee. Maybe, startaddress is not true ?

Ste39 Posts: 4620 Rating: (710)	Hi Simuzer, Regarding the manual, the flashing yellow LED means that is communicating so either try to increase the response time 50/6 0ms or I think you'd better call the WAGO for more details.
