General settings

Memory settings can be defined in the general settings. The disk space for shift statistics and the timeline can be defined. The following should be taken into account when specifying the amount of storage space:

•Recording size of shift statistics: 450 bytes are required per shift entry

•Recording size of timeline: 150 bytes are required per timeline entry

This can be used to calculate the total amount of storage space.

Data objects

At runtime, mapp OEE generates data objects that contain timeline information (OeeT$0) as well as shift statistics (OeeS$0). In addition, a third data object is generated (PerB$0) that contains the current OEE data of a shift. This data object is used to protect the OEE data in the event of power failure. It is important to note that the data object can only be used if "SRAM" has been defined as the memory location. Data is backed up every 10 seconds or as soon as an event occurs, e.g. shift change.

Storage location

Parameter "Record memory" defines the way in which recorded data is saved. The following modes can be selected:

UserROM: All collected data is stored in UserROM.

SRAM: When using battery-backed memory, there must be sufficient memory reserved in the controller configuration. The collected data is saved temporarily to a data object and then backed up in SRAM. Can only be used if the hardware being used is equipped with SRAM memory.

memoryconfiguration

Temporary: Data is saved to DRAM. It is important to note that this data is not protected in the event of power failure or restart!

Defining the shift

Shifts and downtime can be defined with "Shifts". The name of the shift and reason for the downtime must be specified in each case. "Start" defines the starting point; "End" defines the endpoint. The time is specified in milliseconds starting from 00:00:00. If a shift begins at 6:00 AM, for example, then the starting time is 21600000.

Export

Various export settings can be defined with "Export". This includes the name of the file to be exported, for example. "Decimal digits" defines how many decimal positions are saved. Parameter "Column separator" defines the delimiter used to separate PVs in the CSV file. "Decimal mark" specifies how the decimal point should be displayed.
