Hi, can someone please assist, i'm pulling my hair out Im trying to pull some data from a MB TCP simulator on my PC (modsim), i have worked through all answers on the forum(I think) and i just cannot get the data.. Using a modbus master program(modscan) i get the data no problem... See attached picture. I keep getting a 8383 error which according to the help file is "
but looking a a project i done using theserial RS485 modbus functions it all looks fine??? Cheers. |

Did you look in the help for that code? Error in the data address or access outside the address area of MB_DATA_PTR. |
