11.5.1 Possible Data Errors

For point log groups, regardless of the resolution, the following applies when errors occur in log data:

Actual data value of the

but output status is not

(LOG_PT_FAIL)

Data is NO_VALUE

 

 

and status of output is

but the LOG_ERROR_-

and might indicate cor-

 

 

rupted data)

Table 11-8- Data Errors

 

Adisplayed value of DATA N/A (LOG_DATA_NA) is used in medium and low resolution logs when that particu- lar type of data cannot be logged in that resolution. Pulse, one shot, and system list types cannot be logged in medium and low resolution log groups.

11.5.2 Data Compression

Because the user may need to log more data than the default logging of the E2 can hold in memory, the user can set the resolution type in the log manager to determine how the desired points will be logged. E2 converts these analog sample values to this lower resolution (Low or Medium) by:

Adding/subtracting an offset

Multiplying by a scaling factor

Rounding to the nearest integer value of the size appropriate for the desired resolution

11.5.2.1Clipping

Clipping occurs whenever the conversion process results in a sample value that falls outside the range of the selected log resolution. For example, converting a value of 750 PSI to low resolution would result in a compressed sample value of 609 PSI (refer to Appendix E: Com- pressed Point Log Sample Limits and Precision Tab). Low resolution only allows values up to 609 PSI; there- fore, the sample is said to be “clipped.” If the value that will be logged is anticipated to exceed the high or low range for a particular log resolution, a higher resolution should be chosen.

High Clipping occurs when a compressed sample value is above the range allowed by the set resolution. In this case the sample value is considered “high-clipped” and the data recorded will be the high-clipped value and logged at the highest possible valid value.

Low Clipping occurs when a compressed sample value is below the range allowed by the set resolution. In this case the sample value is considered “low-clipped” and the data recorded will be the low-clipped value and logged at the lowest possible valid value.

11.5.2.2Incompressible Data Types

Points of certain data types cannot be compressed due to the nature of their data values. These points are called Incompressible Points. Refer to the following table for the data types that are considered to be incompressible at cer- tain resolutions:

11.5.3 Base Log Group

The Base Log group is a permanent logging group and cannot be deleted. When a new application is added to the system, the inputs and outputs that are logged by default are associated with the Base Log group.

Points are pre-configured to be logged for newly added applications. Many of the most important inputs and out- puts within an application are already pre-configured to be logged, and all of these inputs belong to the Base Log Group. Simply define the inputs and outputs to enable log- ging; no special set up is required. Logging is done auto-
