New HIDS Drum Scales!
Click Here to Learn More!The steps for performing the Tradition Calibration over a network connection are the same on all the HI 3000 and 4000 series units. Mapping would be required in the units. These require the following steps:
1. Setting zero weight
2. Set the Span Weight
3. Send the Command for Cal - Low
4. Add the Span Weight to the Scale
5. Send the Command for Cal - High
The following is an example of doing the calibration in the HI 3030. All network mapping locations are arbitrary locations and may vary in your system.
In the HI 3030, set up mapping as defined in the following example (the example shown will be Channel 1 in the HI 3030):
1. Select Scale 1 Zero weight as destination and a network word(s) as source. The weight can be specified as a short, an integer, or a float, as desired. The name given to the source network word will determine how the data bits in the table are interpreted.
HVO16 = CII1 (Uses ControlNet words 1 and 2 as 32-bit integer zero weight)
2. Set scale 1 span weight as destination and a network word(s) as source
HVO20 = CII3 (Uses ControlNet input words 3 and 4 as 32-bit integer span weight)
3. Map the command-cal-zero bit as destination and some network bit as source
HO2.4 = CI5.0 (Uses ControlNet input bit 0 in word 5 to trigger cal-zero)
4. Map the command-cal-span bit as destination and some network bit as source
HO2.8 = CI5.1 (Uses ControlNet input bit 1 in word 5 to trigger cal-span)
5. We will also map in the command status from HSI3
CSO2 = HSI3 (Reads command status word into ControlNet output word 2)
NOTE: The Most Significant bit of HSI3 is the Data-valid flag. Status is valid while the bit is high. The status is held valid while the command bit is high.
Procedure:
1. Put desired low cal weight value into (PLC) ControlNet output words 1 and 2
2. Put desired high cal weight value into ControlNet output words 3 and 4
3. Empty the scale
4. Send the low-cal Command by setting word 5, bit 0 high
5. Wait for status to arrive in word 2
6. Remove command by clearing word 5 bit 0
7. Add span weight to scale and let settle to come out of motion
8. Send the high-cal Command by setting word 5, bit 1 high
9. Wait for status to arrive in word 2
10. Remove command by clearing word 5, bit 1
A successful status return is 0x8000 in the HI 3000 series units, where the most significant bit indicates valid status, and the rest of the word is the status value, in this case 0, meaning success. A successful status return is 0 in the HI 4000 series units.
11. Remove weight
The same procedure would be followed in the other HI 3000 and HI 4000 series units, though the mapping terms may differ.
