Fig. 5.1.15.1.-2 Status registers
When the value of the FR/ER bit is 1, there is one or several unread fault/event
records. If time synchronization is realized via a digital input, either the SP (second-
pulse) or MP (minute-pulse) bit will be activated.
Refer to Table 5.1.18.-1 for IRF codes and Table 5.1.18.-2 for warning codes.
