The PLC network will be formed by CPE, HE and Repeaters and

Nevertheless, in the diafram is only represented one element of the PLC networks.
The MV cubicle is considered an unique device
This device is fromed by the gateway and the
MV cubicle controller wich is formed by the Protection

As it is defined now, it seems unovidable that each Use Case message has to be translated between pairs of protocols at
each integris device (DLMS; 61850,104, modbus and so on). These add complexity and delay to INTEGRIS,
affecting the performance of applications. To mitigate the problem, the integris device will have to be defined
in a 61850 centric way. This means that the rest of protocols will suffer translation delays
but the native 61850 equipment will suffer less delay because they don't require the translation.
