ESP8266 - read Holding register from Power meter - MODBUS

Dear Freelancers,

I need Arduino sketch for reading Holding registers from Power meter via Modbus.

I have 3 phase Power meter with Modbus communication (NOARK Ex9EMS 3P 4M CT MB 2T) which is connected via Modbus (A - B) on TTL To RS485 Adapter 485 Serial Port UART.

RS485 adapter is connected to WEMOS D1 ESP8266 Mini Pro: Rx&Tx and 5V & GND.

I would like to read modbus addresses on Serial monitor on Arduino IDE.

Please see details about Power meter and wiring in attachements.
