REQUIRED CONTROLLER TAGS
CH1/CH2 SCALE SET
HM1734WM1_a[0]
HM1734WM1_a[3]
Full scale setting for CH1, CH2
Value is determined by capacity of load cell and by resolution required.
Example: 10KG = 10,000
SET AUTOCAL REFERENCE WEIGH VALUE CH1, CH2
HM1734WM1_a[1]
HM1734WM1_a[4]
Enter desired value to read based on known weight from calibrate procedure.
GET WEIGH VALUE CH1, CH2
HM1734WM1_a[2]
HM1734WM1_a[5]
Reports measured weigh value in RUN mode.
Reports raw A/D count value in CAL mode.
SET AUTOCAL CH1, CH2 Enable Bit
HM1734WM1_a[6]
HM1734WM1_a[7]
With ladder logic provided, an auto-cal method for calibrating is available.
Set to (1) to initiate Auto-Cal for the channel.
Ladder logic will clear the bit.
SET AVERAGE SAMPLE COUNT
HM1734WM1_a[8]
Set number of samples to take for average type filter.
Two Channel operation; Max value (50).
One Channel operation; Max value (100).
SET mV/V CH1, CH2
HM1734WM1_b[0]
HM1734WM1_b[1]
CH1/CH2 MV_V Settings
Enter 2.0MV/V for nominal load cell.
Actual value is from load cell specification.
AUTO CAL mV/V
HM1734WM1_b[2]
HM1734WM1_b[3]
Values generated by Auto_Cal routine.
