DLMS (''Device Language Message Specification'') is a set of standards used for communication between various meters, monitoring equipment, and the respective controllers. It uses '''TCP/IP or serial communication''' and utilizes '''Client and Server topology''', where the client polls the data from the server (''usually gas/electricity/water meter''). It should be noted, that there often is confusion between IEC 62056-21 and DLMS. '''IEC 62056-21 is not DLMS'''. | DLMS (''Device Language Message Specification'') is a set of standards used for communication between various meters, monitoring equipment, and the respective controllers.
