IM MW100-01E
• Special computation processing (excluding TLOG and CLOG computation) for
measurement channels
Reference Channel Status Notation Process Description
Abnormal input value Error Computed result is an error
Skip Continue computation using previous value of
channel on which abnormal value was input
Overflow value Over Compute using overflow value
Skip Continue computation using previous value of
channel on which overflow value resulted
Limit
*1
The overflow value is replaced with the upper or
lower limit, and computation continues
*1 The lower/upper limit value replaced on the measurement channel differs depending on the
computation type.
Measurement channel: Measurement range upper and lower limit
Scaled measurement channel: Upper and lower limit of scaling
• Special processing for reference channels of TLOG and CLOG computations
TLOG Computation
Reference
Channel Status
Notation MAX MIN P-P AVE SUM PSUM
Abnormal input
value
Error Computed result is an error
*3
Skip Current TLOG computation is skipped
Overflow value Error Computed with the
overflow value as-is
Computed
result is a
+OVER
*2
Computed result is an error
*3
Skip Current TLOG computation is
skipped
Limit The overflow value is replaced
with the upper or lower limit,
and computation continues
*4
CLOG Computation
Firmware version R3.04
Refaerence
Channel Status
Notation MAX MIN P-P AVE
Abnormal input
value
Error Computed result is an error
Skip Computation is carried out without the channel on which the
abnormality occurred
Overflow value Error Computation
occurs with the
overflow value as-
is
Computed result
is +Over
*2
Computed result is
an error
Skip Computation is carried out without the channel on which the
overflow occurred
Limit The overflow value is replaced with the upper or lower limit,
and computation continues
*4
Firmware version R3.03 or earlier

*2 If the data is plus over only or minus over only, the computed result is an error
*3 Once an error occurs, computed results continue to be errors until computation is cleared
*4 The lower/upper limit value replaced on the reference channel differs depending on the input
type.
