4.4.9 DiamMeasEnbl
This input activates the measured diameter as the actual diameter output
DiamCalc_in. This is set high when the actual diameter is to be measured and the
controller should not calculate the diameter based on roll revolutions and length
wound. Setting this input low does not inhibit usage of measured diameter for a
preset. When set high, the measured diameter rate of change will be limited by
DiamRate_inRev input, the measured diameter will be limited by
DiamMinEC_in/DiamFR_in and the DiamCalc_in output will be held at last state
when the diameter calculator is disabled.
Usage – Set high when using measured diameter for actual diameter. Set low when
using measured diameter only for preset and calculated diameter for actual (running)
diameter.
4.4.10 DiamMeasInput
This is the input from the external diameter measurement device.
Usage – Connect to the tag for the external measurement device. This should be the
“raw” data from the device.
4.4.11 DiamMeasMin_DC
This is the minimum value of the measurement device raw data.
Usage – Set for the minimum value the measurement device will output.
4.4.12 DiamMeasMax_DC
This is the maximum value of the measurement device raw data.
Usage – Set for the maximum value the measurement device will output.
4.4.13 DiamMeasMin_in
This input scales the measured diameter (DiamMeasMin_DC) to inches.
Usage – Enter the actual diameter of the measured roll for the DiamMeasMin_DC
value.
4.4.14 DiamMeasMax_in
This input scales the measured diameter (DiamMeasMax_DC) to inches.
Usage – Enter the actual diameter of the measured roll for the DiamMeasMax_DC
value.
4.4.15 DiamPresetCmmd
This is the command bit from the DiamPreset routine. When the input is high, the
diameter calculator will be set to the DiamPresetVal_in. Do not set this bit when the
machine section is running.
Usage – Connect the yDiamPresetCmmd tag (default) to this input.
4.4.16 DiamPresetVal_in
This is the preset value from the DiamPreset routine. When the DiamPresetCmmd is
high, the DiamPresetVal_in is loaded into the diameter calculator.
Usage – Connect the yDiamPresetVal_in tag (default) to this input.
