Posted 19 November (edited) You should check if the communication settings of the software are correct (model type in particular). Other reason could be wrong PLC MPU inside the package (aftermarket PLC board inside an DVP12SА package). I have had such cases. You may also have such problem if using improper USB<->RS-485 converter. Edited 19 November by IvanBratanov Share this post Link to post Share on other sites
Posted 19 November In case everything with the RS-232 or RS-485 converters used is OK, you should also check the firmware version of the PLC. If there is an older PLC you should find an older version of WPL for example. Share this post Link to post Share on other sites
