5.4.16 BFM#71 to #74: Lower limit error setting / BFM#81 to #84: Upper limit error setting
Setting range: See below.
Initial value: See below.
Numeric data type: Decimal (K)
Set the upper/lower limit error data so that the upper/lower limit error status (BFM#26) can be detected.
The data setting range depends on the input mode set in BFM#0.
The following table shows the data setting range for each input mode:
1. Cautions regarding upper/lower limit error setting
• To use the set upper/lower limit error data, be sure to turn on the upper/lower limit error detection function
(b1 of BFM#22).
• To use the data addition function (b0 of BFM#22) together with this function, be sure to add the addition
data (channels 1 to 4: BFM#61 to #64) to the upper/lower limit values to be set. In addition, observe the
data setting range.
