HandlingofMathChannelData(DifferencebetweenCxxxandRCxxx)
• Cxxx uses the measured results of communication input from a PC or the like (display
values of communication channel) in computation.
• RCxxx uses communication input from a PC or the like (display values of communication
channel) directly in computation.

Computational Processing When Measurement Mode Is Set to Dual Interval
• Computational is performed at the scan interval of the measurement group set with the
master scan interval. If a channel in a measurement group using a scan interval different
from the master scan interval is used, it is indefinite as to which measured value of this
channel in time will be used for the difference calculation.
• Pulse integration (TLOG.PSUM) is performed only when the measured value of the
channel used in the calculation expression is updated. However, computation is
performed at the master scan interval.
Computational Processing When the Measurement Mode Is Set to High
Speed
Computation is performed at the scan interval, but computational processing is performed at
100 ms.
