How do I set the number of decimal points on my HI 1746WS?

The Multiplier setting in the HI 1746WS will determine the format and number of decimal places for the data. If a multiplier other than zero is used, then the values returned are integer. The value of the multiplier will determine the decimal point resolution.

If the Multiplier is non zero, then the unit will take the value, multiply it by this multiplier, then send the integer portion (value to the left of the decimal point) to the PLC. The user would need to divide the value by the same Multiplier value to return the reading back to normal.

Normally the Multiplier would be a power of 10. This allows a change in the decimal point position without changing the value.

The output table word number 15 sets the weight multiplier value.
0 = floating point
1 = Integer and no decimal point
10 = Integer and 1 decimal point
100 = Integer 2 decimal points

If you need integer values with one decimal place resolution set the multiplier to a value of 10.

NOTE: The Multiplier setting will effect all 4 byte parameter and weight values read from the module and all 4 byte parameter values being written to the module would need to be adjusted by this Multiplier setting also before being written to the module.

As a side note, the Rate of Change multiplier is word 16. A word value of:
1 = 1 unit/sec.
10 = 1.0 unit/sec.
60 = 1 unit/minute
600 = 1.0 units/minute
3,600 = 1 unit/hour
36,000 = 1.0 units/hour (one decimal point resolution)
