The driver support for the Trilog PLCs is not provided by the manufacturer, Weintek. The drivers were added by the US distributor KEP. You can download a version of Easy Builder Pro from their website kep.com that has both of the TRI_FX and the TRI drivers installed.
Adding the TRI_FX and TRI .dll and .e30 files will not make these PLC drivers visible for EasyBuilder Pro down loaded from Weintek. There is another file, "devicetype.def", that has been modified by KEP to reference the TRI_FX and TRI drivers. The ".def" file is located at:
C:\Program Files (x86)\EBpro
If you copied the "deficetype.def" file from a version of EasybuilderPro supplied by KEP as well as the drivers, you could make your version work.
Please note that the TRI driver that supports the FMD series of PLCs does not support access to DM32[] (32 bit access) very gracefully. If you wrote conversion macros for the HMI you can use the TRI driver to access DM32.
You can use the version of EasyBuilder Pro that you have installed if you use the Modbus RTU driver with the FMD series PLC.
