Note:
• The central unit OCI600 must have a memory card inserted. The logged data will be
transferred to the memory card. The inserted memory card must be formated
• For each trend definition and central unit, only one logging process can be started.
With the OZW775, a maximum of 5 trend definitions can be stored, with the
OCI600, a maximum of 1
After the trend definition has been transferred to the central unit, the status of the
trend definition will change from not available (trend definition highlighted in white) to
pending (trend definition highlighted in light-blue).
The central unit starts logging automatically, depending on the trend definition
settings:
• Directly after receiving the trend definition (Start directly after loading)
• After the start time (Start Date/Time) of logging has been reached
As soon as the central unit has started logging, the status of the trend definition
changes to active (trend definition highlighted in yellow).
After the trend definition has been transferred to the central unit, the connection to the
plant can be cut. After cutting the communication, the status of the offline trend is no
longer available on the central unit. Hence, all trend definitions will be highlighted in
white:
• The central unit starts and stops logging automatically, depending on the setting of
the loaded trend definition
• The central unit performs logging and storage of the values automatically,
depending on the selected data points in the loaded trend definition
When a connection to the central unit is reestablished, the status of the offline trend in
the central unit will also be available again and the trend definition that is active in the
central unit will be appropriately highlighted:
• Pending (light-blue): The trend definition has been transferred to the central unit.
The time of execution has not yet been reached however. Logging will automatically
be started later
• Active (yellow): For this trend definition, logging in the central unit is currently in
progress
• Executed (green): For this trend definition, logging in the central unit has been
completed
• Not available (white): This trend definition is not currently stored in the central unit.
In this central unit, there is no logging for this trend definition in progress
• Error (red): The trend definition is erroneous and cannot be evaluated.
During logging, you can already start with the evaluation of the values of the current
offline trend logging logged thus far, or you can do this after logging is completed.
To manually stop active logging (yellow), use the right mouse button to click on the
trend definition and select Stop trend logging. Trend logging is now highlighted in
green, which means that logging has been completed.
