  1. Hi All First ever post so forgive me if I do anything wrong. My customer has given me an FX5Uc PLC and a Delta DOP-B03S211 HMI. Comms need to be via serial. Ethernet not an option. I have configured the HMI as the Delta DOP datasheet(see attached) I have configured the PLC as: - MC-Protocol - 19200,8,1,Odd I however get an HMI error: - ########################################## COM 1 STATION 0: COMMUNICATION ERROR 3. READ ERROR No Response from Controller ######################################### I have created a simple page on the HMI  consisting of a push button (M reg) and a numeric display (D reg). When pressing the push button I can see the change in the PLC. (Transmission good) Any change of the D reg in the PLC is not reflected on the HMI. Confirms the message. I have tried all combinations of settings on both side but no joy. The PLC seems to be happy as it receives and transmits ok with no errors. Can any one see what I am doing wrong?
