When necessary, diagnostic information can be transmitted via interfaces. There is an
option of receiving an error code register using Modbus RTU/TCP, IEC 60870-101/104
protocols. This register contains current set of diagnosed states. It is also possible to
transmit the self-diagnostic information in form of DI, choosing which specific parameter
or error to pass on (fig. 9.1).
Figure 9.1. Diagnostic information in form of DI
Self-diagnostics also includes temperature measuring inside the device. This could be
transmitted by an additional register.
