3-10-7 Event History Setting

Event History information is stored in the Recipe Data Field.
When the check box [Save to Recipe Data Field] in the [PT Property] is checked, the system stores the Event
History information of executed Event to the Recipe Data Field. Since the system automatically performs the
storing, the user does not have to care about the method to store the Event History information.
The destination to store the data will be specified from the address set in [Start Address] of the system
parameters. The default address is "0".
The data stored to the Recipe Data occupies 16 words for each event. The example of size calculation to
store the Event Log is shown as below. The data which was stored in the Recipe Data cannot be exported to
external memory.

The size of the stored memory is 200 x 16 = 3200 words. The address of Recipe Data Field is "read
only area". If writing is performed to the area, it may result in unpredicted condition. Although the user
can specify the starting address freely, pay attentions to the following points.
(1) The specified addresses cannot be specified overlapped with other components and others.
(2) Since the addresses after RW60000 are reserved by the system, the memory area exceeds
RW60000 cannot be specified.
• When the storage period is set, the file deletion is performed at the first sampling after the startup
and every 24 hours. At this moment any files which is beyond the storage period should be deleted.
