RTC Option Module
GM7U series provides RTC (Real Time Clock) function for GM7U series (G7E-RTCA).
The RTC module will send the RTC data to main unit per every scan. By the super capacitor back up, the RTC module keeps
operating while the power is off or 20m seconds momentary power off. It can be used for time-scheduling control or recording
an error occurrence time. The RTC data is updated into system operation status flag per every scan.

(4) Read/Write of RTC data
Select the menu ‘Online – PLC Information’ win GNWIN software.
1)
The RTC module is sold with no initial RTC data setting. Be sure to input the RTC data when use a RTC
module first time.
2)
The RTC module may show abnormal operation when an improper RTC data is written.
Example) 14(Month) 32(Date) 25(Hour)
In this case, an error will be cleared with new RTC data.
3)
The system flag _RTC_ERR of _CNF_WAR will turn On when a RTC data error occurred. _RTC_ERR flag
will turn Off automatically when the error is cleared.
