Page 8: 5．Details Of Commands
5. Details of Commands The commands that can be executed for the equipment will be described below. Please note that KOFLOC will bear no responsibility for motions resulting from the use of commands other than those specified here. １）RMFS：Acquisition of the maximum full scale flow rate [significand] The maximum full scale flow rate [significand] is acquired. -
Page 9: Rfrc：acquisition Of The Flow Rate Reference Temperature Condition
MJ400３２１A1 ４）RCFS：Acquisition of the full scale flow rate [significand] The full scale flow rate [significand] is acquired. The full scale flow rate [significand] refers to the significand of the full scale flow rate currently set to the equipment and is used to calculate the full scale flow rate currently set to the equipment together with the flow rate decimal point position [number of decimal places] and flow rate unit. -
Page 10: Rpgt：acquisition Of The Calibration Gas Type
MJ400３２１A1 ８）RPGT：Acquisition of the calibration gas type The calibration gas type used for equipment calibration is acquired. Data Command: None Response: Decimal 1 digit (fixed length 1 byte) 1：N (Nitrogen) ９）RCGT：Acquisition of the gas type The gas type that has been set is acquired. Data Command: None Response: Decimal 1 digit (fixed length 1 byte) -
Page 11: Rccf：acquisition Of The Cf Value
MJ400３２１A1 １１）RCCF：Acquisition of the CF value The CF value that has been set is acquired. The CF value is used for the CF conversion mode. This is expressed always based on N (nitrogen) (1000) regardless of the calibration gas types. Data Command: None Response: Decimal 4 digits (fixed length 4 bytes) -
Page 12: Rcfr：acquisition Of The Instantaneous Flow Rate [Significand]
MJ400３２１A1 １５）RCFR：Acquisition of the instantaneous flow rate [significand] The instantaneous flow rate [significand] is acquired. This is used to calculate the instantaneous flow rate together with the flow rate decimal point position [number of decimal places] and flow rate unit. Data Command: None Response: Decimal 4 digits (fixed length 4 bytes) -
Page 13: Rcvs：acquisition Of The Valve Status
MJ400３２１A1 ２０）RCVS：Acquisition of the valve status The present valve status is acquired. Data Command: None Response: Decimal 1 digit (fixed length 1 byte) 0：Fully opened, 1：Controlled, 2：Fully closed, 3：50％opened ２１）RSFD：Acquisition of the set flow rate [significand] (digital) The set flow rate [significand] (digital) that has been set is acquired. This is used to calculate the set flow rate (digital) together with the flow rate decimal point position [number of decimal places] and flow rate unit. -
Page 14: Ralm：acquisition Of The Alarm Occurrence Status
MJ400３２１A1 ２４）RALM：Acquisition of the alarm occurrence status The alarm occurrence status is acquired. Data Command: None Response: Decimal 1 digit (fixed length 1 byte) 0：No alarm (normal) 1：Alarm present (Sensor error) 2：Alarm present (valve overheat) 4：Alarm present (set value storage circuit error) When several alarms are present, their values are added. -
Page 15: Wlfd：setting Of The 0 - 0.5% Range Flow Rate Indication
MJ400３２１A1 ２８）WLFD：Setting of the 0 – 0.5% range flow rate indication Set the 0 – 0.5% range flow rate indication. Data Command: Decimal 1 digit (fixed length 1 byte) 0：0 – 0.5% range flow rate indication used 1：0 – 0.5% range flow rate indication not used (Forced indication of “0”) Response: None ２９）RAZS：Acquisition of the auto zero... -
Page 16: 6．Flow Rate Expression・・・・・・・・・・・・・・・・・・・・・・15
MJ400３２１A1 6. Flow Rate Expression The maximum full scale flow rate, full scale flow rate, instantaneous flow rate, set flow rate (digital) and set flow rate are expressed by a combination of the significand and flow rate decimal point position [number of decimal places] and flow rate unit. Note that flow rate decimal point position [number of decimal places] and flow rate unit are used commonly for each flow rate and cannot be changed. - Page 17 MJ400３２１A1 URL：http:// www.kofloc.co.jp...
