This is a great video sir. And many thanks. Tried it and it worked. However, i have got 2 questions.

1. So you do not need to map the MB_Data.Hold_Reg to the PLC tags in order to read or write to it? Will it still be same for analog input cards like reading the Flow, Pressure and Temperature sensor data?

2. Would mapping also be required between MB_Data.Hold_Reg
(Buffer) and other DB's in the program? Or will it work straight away just like the PLC tags? For instance, DB_Powermeter?

Good video...I want to ask how if 1 Siemens PLC communicates with many ESPs at once? What needs to be changed is the ID?

Excellent video. Thanks for sharing. I've successfully done Modbus Server like on the video, but when I try to read data from Micrologix 1400 Modbus Client it does not work. I get the error "Local communication channel is shut down".
