ErrorDataHandling(TLOG,CLOG,andReports)
If an error occurs in the channel data, the error data is discarded, and the computation
continues. If all the data are in error, an error results.
The following types of data are considered error data.
• Channels set to skip or Off.
• The measured result on an I/O channel is error (A/D converter failure, etc.).
• I/O channel input is in a burnout condition.
• The computed result on a math channel is error.
HandlingofOverflowData
1
1 Refers to over range on an I/O channel, computation overflow on a math channel, and over
range on a communication channel.
For TLOG, CLOG, and Reports
When the channel data is overflow data, the GX/GP handles it as follows:
Computation Type Description
Average value or sum value Set the handling to Error, Skip, or Limit.
Error: Sets the computation result to computation error.
Skip: Discards overflow data and continues the computation.
Limit: Replaces overflow data with the limit value and continues the
computation.
Limit value:
Measurement channels: Upper or lower limit of the selectable range of
the specified range or the scale upper or lower limit
Math channels, communication channels: Span upper or lower limit
Maximum, minimum,
Maximum – minimum
Set the handling to Over or Skip.
Over: Computes by using the overflow data.
Skip: Discards overflow data and continues the computation.
