The (un-)installation of Asset Vision on FIM node might cause an error of the HART driver and HART CommDTM driver. This effects that the FIM can´t connect to HART devices anymore. To repair this issue, it is mandatory to launch the “DTMSetupLauncher.exe” in the installation folder of the Asset Vision Basic tool. The DTMSetupLauncher provides a wizard to install the missing or defect drivers. If the drivers are missing, only “install” is possible, if the drivers are broken, “repair” is to choose. After the driver installation a restart of the node is necessary.
