Real-time clock (RTC)
FC610 keeps an internal real-time clock to record alarms, operations, events with time
stamps. The RTC operates to a timing accuracy of 10ms.
The setting of the internal clock may be manually from the front HMI panel or via dedicated
configuration software MConfig-G with the setting accuracy to 1 second.
For higher timing accuracy, the RTC setting is expected from fieldbus, e.g. through Modbus
RTU. A time setting to an accuracy of 10ms may be broadcasted to FC610 from a Modbus
main station. More details of writing RTC from Modbus network are available in separate doc-
ument ‘1TNC928247 FC610 Modbus Protocol Implementation’.
When FC610 is used with a MS572, the digital converter, in a Modbus TCP network (fig25), it
is also possible to synchronize time from external SNTP server to MS572 before further
broadcasting to FC610.
SOE
Other than recording single alarm, trip and operation, FC610 records up to 256 events with
time stamp.
