What are the differences between IEC 61142 (ex 1142) and IEC 62056-31?
The IEC 1142 (called later IEC 61142) was the oldest version of EURIDIS standard which became in year 2000 to the IEC 62056-31. The actual IEC 62056-31 is fully compatible with IEC 61142 which guarantees the using of IEC 61142 and IEC 62056-31 products on the same bus. In addition to IEC 1142, the IEC 62056-31 allows the following functions: * Point to point remote transfer, which is a simplified remote programming service (without authentication) * Broadcast remote transfer, * Communication with non-energised secundary stations * Alarm function, * Forgotten station call exchange including “Discover” algorithm (to avoid any collision while detecting new secondary stations), * DLMS services using the same physical medium and the same physical layer.
