3-6 DP-V1 Service This read command is useful when you use the calculation function with the detection mode set to hold detection (peak hold) and when you read the R.V. value of the main/expansion unit(s) for calculation as well as the calculation results. The read command for the P.V. value can read the held values, while that for the R.V. value reads the raw value when the command is received. Therefore, the read R.V. value is not synchronized with the latest values. This read command can read the R.V.
