Overview of Logging/Trace Function1-61.2.2 Overview of Trace Function Overview• The trace function is used to record arbitrary contacts and data information together withtime stamp information in the buffer memory in the control unit at any time.• Logging data can be uploaded from the buffer memory to the tool software after the traceoperation, and can be displayed as a time chart. Traced data can be saved in SD memorycards as CSV format files.• When the trace stop condition is set to bit device, the operation can be stopped after loggingdata of the specified number of samplings after the stop condition has been met.• Use the "Logging/Trace Settings" menu of tool software to set the conditions.• The settings are downloaded to the PLC as part of project data, and stored in the non-volatile memory.• The trace operation is executed by any of those operations; (1) tool software, (2) dedicatedinstructions or (3) Autostart by the setting. SpecificationsItem Specifications RemarksNumber of logs Max. 128 devices (Max. 256 words) per record -Buffer memoryMax. 64 K wordsCan be divided into max. 4 (LOG0 to LOG3) areas foruse.Capacity per division: 4K words to 64K wordsShared with the loggingfunction.Trace start Selectable from the tool software, instructions orautostart. -Trace trigger conditionBit device ON (Note 1)Cycle: In msec. (Note 1)Instruction: Executes F420 (LOGST) instruction withan arbitrary condition and starts tracing.-Trace stop condition Bit device ON (Note 2), (Note 3)Buffer full -File format Data is saved in CSV format.Arbitrary comments can begiven.The upper limit of thecapacity on the file systemis 4 GB.(Note 1): The trace operation is executed when the condition is met at the end of scan.(Note 2) When selecting “Bit” for the trace stop condition, logging data of the specified number of samples is possibleafter the condition is met.(Note 3) Unlike the file determination condition of the logging function, logging of data for the specified number ofsamples starts when the bit device changes from OFF to ON.
