FX2N-5A Special function block Buffer Memory (BFM) 7
7-17
7.2.4 BFM 6 to BFM 9 Averaged Input Channel data (READ only)
The average A/D conversion data of each input channel is displayed in BFM 6 to BFM 9. The
number of samples to calculate the average data is influenced by the setting in BFM 2 to BFM
5) described above. The data displayed is "processed data", therefore, offset and gain
calculations and Scaling function calculations and digital filtering (if selected) are already
performed before the average value is calculated.
7.2.5 BFM 10 to BFM 13 Immediate Input Channel data (READ only)
The immediate A/D conversion data of each channel is displayed BFM 10 to BFM 13. The data
displayed "processed data", therefore, offset and gain calculations, Scaling function
calculations and digital filtering (if selected) are already performed.
7.2.6 BFM 14 Analog Output data (READ/WRITE)
BFM 14 receives the analog output data for the DA (Digital Analog) converter. For this data,
offset/gain calculations or the Scaling function calculation will be performed, and direct
output function calculation. Thus, "processed" data will be sent to the DA converter.
7.2.7 BFM 15 Calculated Analog output data (when direct control function is active)
(READ only)
If the direct output control function (see BFM 23) is enabled, the result of the calculation
process that is written to the analog output is read back to the PLC via BFM 15.
7.2.8 BFM 16 to BFM 17 Reserved
