ConMod P1Modbus – Meter P1 to Modbus RTU/TCP converter

CONMOD P1Modbus The P1 interface converter to Modbus RTU/TCP

Overview

ConMod P1Modbus is a small-size industrial protocol converter for smart Meters with P1 interface output to convert meter data into industrial standard protocols Modbus RTU and Modbus TCP with interfaces RS485 and Wi-Fi (2,4GHz).

Designed to convert smart meter data into the most popular industrial protocol Modbus. The solution perfectly fits for integration with energy management systems, remote monitoring, SCADA systems and etc.

ConMod P1Modbus is compatible with the DSMR interface and supports different versions and variations of data formats. Also, ConMod P1Modbus has a menu to show RAW data (P1 telegram) collected from the smart meters to enable comparison with converted data in Modbus registers.

ConMod P1Modbus is designed for industrial applications with cybersecurity in mind to be able to disable Wi-Fi communication and avoid illegal communication over Wi-Fi in critical infrastructure projects.
