Hi, i'm using "Modbus_TCP_energyAdv" blocks for connecting Sentron Pac 2200 through Modbus TCP. The block functions perfectly but sometimes i can't read the values and appears error 8411 without any apparent reason. When i work to my plc during the week and i frequently upload new code the blocks works perfectly but, when i leave the plc for the weekend (more or less 60 hours) without any interaction or code upload i retrieve the 8411 error code. The only way to restore the correct functionality is compile the software and upload it (the software is the same as before) and magically the blocks works. Modbus TCP Energy ADV- this is the official block i'm using, i ha ve the TIA14 version Thank you so much. |

Actually re-uploading a new code didn't work, i had to stop and re-run the plc. |
