Posted 28 Aug 2017 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) Like this Share this post Link to post Share on other sites

Posted 29 Aug 2017 Did you set the RS232 port on the PLC to match the settings on the HMI? Share this post Link to post Share on other sites
