DVP-PLC Application Manual
2-73
M1017
±30 seconds
correction
From “Off” to “On”, the correction is enabled.
0 ~ 29 second: minute intact; second reset to 0
30~ 59 second: mimute + 1; second reset to 0
M1076 RTC malfunction Set value exceeds the range; dead battery
M1082 Flag change on RTC On: Modification on RTC
D1313 Second 0 ~ 59
D1314 Minute 0 ~ 59
D1315 Hour 0 ~ 23
D1316 Day 1 ~ 31
D1317 Month 1 ~ 12
D1318 Week 1 ~ 7
D1319 Year 0 ~ 99 (last 2 digits of Year in A.D.)
2. If the set value in RTC is incorrect, the time will be recovered as “Saturday, 00:00 Jan. 1, 2000” when PLC is
powered and restarted.
3. D1313 ~ D1319 will immediately update the RTC only when in TRD instruction or WPLSoft monitoring mode.
4. How to make corrections on RTC:
a) Use TWR instruction fir SA/SX/SX/EH/EH2/SV series MPU. See API 167 TWR for more details.
b) Use WPLSoft or digital display panel DU-01.
