I have downloaded a program into the PLC, downloaded a program in the HMI terminal, and connected my PLC to the HMI via a custom made RS232 cable. When I turn them on, the correct screens appear on the HMI terminal, but no data is coming through from the PLC. After a few seconds, a pop-up appears saying "[2]PLC No Response 00-00-1". Does anyone know the meaning of this message, or what I might be doing wrong or missing out? CPU used: CP1L-M60DT1-D (with a CP1W-CIF01 serial adapter) HMI terminal used: NB3Q-TW00B Details for the RS232 cable: NB pin 2 (SD) to CP1L (CP1W-CIF01) pin 3 (RD) NB pin 3 (RD) to CP1L (CP1W-CIF01) pin 2 (SD) NB pin 9 (SG) to CP1L (CP1W-CIF01) pin 9 (SG) CP1W-CIF01 Bridge between pin 4 (RS) and pin 5 (CS)
