Hi, Can you please explain mapping Modbus IP in ScadaBR scada with slave ESP8266, because ist hard to know how to. It will be good for beginners to have the same example of mapping... Thank you. openplc1.png

I need to update the table on the website to add the slave devices address range. But the formula to find the address is pretty simple:

%QX[major].[minor] = coil 8*major + minor

So:
QX100.0 = coil 8*100 + 0 = coil 800
QX100.1 = coil 8*100 + 1 = coil 801
QX103.4 = coil 8*103 + 4 = coil 828
... and so on

Thank you very much. I have another question, I am missing in reference-modbus mapping also  memori BIT mapping... Have OpenPLC memory BIT ? How its mapping ? thank you. 🙂

OpenPLC does not have memory bit, however you can use any coil that is out of bounds of the physical hardware (like %QX9.0 for example) as a memory bit
