OFF when the trace is completed.Turn this bit from OFF to ON to establish the triggercondition. The offset indicated by the delay value (positiveor negative) determines which data samples arevalid.When a data trace is started by turning this bit fromOFF to ON from the CX-Programmer, the PLC willbegin storing data in Trace Memory by one of the threefollowing methods:1. Data is sampled at regular intervals (10 to 2,550ms).2. Data is sampled when TRSM(045) is executed inthe program.3. Data is sampled at the end of every cycle.The operation of A50815 can be controlled only fromthe CX-Programmer.These words contain the time at which the power wasturned ON. The contents are updated every time thatthe power is turned ON. The data is stored in BCD.A510.00 to A510.07: Second (00 to 59)A510.08 to A510.15: Minute (00 to 59)A511.00 to A511.07: Hour (00 to 23)A511.08 to A511.15: Day of month (01 to 31)These words contain the time at which the power wasinterrupted. The contents are updated every time thatthe power is interrupted. The data is stored in BCD.A512.00 to A512.07: Second (00 to 59)A512.08 to A512.15: Minute (00 to 59)A513.00 to A513.07: Hour (00 to 23)A513.08 to A513.15: Day of month (01 to 31)These words are not cleared at startup.Contains the number of times that power has beeninterrupted since the power was first turned ON. Thedata is stored in binary. To reset this value, overwritethe current value with 0000 hex.This word is not cleared at startup, but it is clearedwhen the Memory Corruption Detected Flag (A395.11)goes ON.The time that operation started as a result of changingthe operating mode to RUN or MONITOR mode isstored here in BCD.A515.00 to A515.07: Seconds (00 to 59)A515.08 to A515.15: Minutes (00 to 59)A516.00 to A516.07: Hour (00 to 23)A516.08 to A516.15: Day of month (01 to 31)A517.00 to A517.07: Month (01 to 12)A517.08 to A517.15: Year (00 to 99)The previous start time is stored after turning ON thepower supply until operation is started.ON: Trace inprogressOFF: Not tracing(not sampling)ON: Trace triggercondition establishedOFF: Not establishedOFF to ON: Startsdata trace (sampling)Turned ON fromProgrammingDevice.See Function column.See Function column.0000 to FFFFhexadecimalSee Function column.StatusaftermodechangeRetained Cleared ---Retained Cleared ---Retained Cleared ---RetainedStatus atstartupSee Functioncolumn.Write timing/Related flags,settingsRefreshedwhen power isturned ON.Retained Retained Written atpower interruptionRetained Retained Refreshedwhen power isturned ON.A395.11Retained Retained See Functioncolumn.A-130 CJ2 CPU Unit Software User’s Manual
