Most external HMI are using port no. 8000, PLC port usually set to 502.
Read/write functions currently supports Int 16, Int 32, Float, Float swapped, Boolean data types.
Software was tested on HMI panel Weintek MT6070iH, Delta DVP20EX2 PLC, Siemens s7-1200 PLC

Ratings and reviews

There is a lot to love in this app. Modbus over BT works great. Display scaling is a great future when I share my app between phones. There is 32bit little/high endian handling. Changing BT server to all elements is great. I wish I had simple scripting. Slava Ukraine!

It works great. But the ModBus-Modul i use, needs "Write Multiple Registers (0x10)".Is it possible to program this in one of the next versions? With 0x03 and int16 it doesn't work with the module "simple EVSE WB". Reading works fine.

Amazing app, in no time you can setup a nice panel! Bunch of thanks to the développer, I am more than happy to donate in order to remove the small advert banner at the bottom of the screen.
