JomEMS Advanced Gateway

Advanced Gateway for the fast reading of data from meters with DLMS and MODBUS protocol. Instantaneous conversion of reading to JomEMS.

The DLMS protocol (Device Language Message Specification) is used in the context of the meters and in particular of energy meters for the reading of operating data. The reference standard is IEC 62056. It is based on services that allow reading the objects, defined OBIS, into which are mapped the operating values of the meters according to standard profiles.

MODBUS Protocol is a messaging structure, widely used to establish master-slave communication between intelligent devices. A MODBUS message sent from a master to a slave contains the address of the slave, the ‘command’ (e.g. ‘read register’ or ‘write register’), the data, and a check sum (LRC or CRC).

Since Modbus protocol is just a messaging structure, it is independent of the underlying physical layer. It is traditionally implemented using RS232, RS422, or RS485

JomSoft provides advanced gateway through which is possible to read by communicating with DLMS or MODBUS protocol, data provided by the meter equipped with DLMS or MODBUS protocol.
