How can I change the resolution of my weight reading from the HI 1746WS?

With the HI 1746WS module, the Multiplier setting will determine the format and number of decimal places for the data. This is word 15 of the Output Table for the Module.

If the Multiplier is zero, then the data will be transferred in IEEE floating point format.

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 internal weight value, multiply it by this multiplier and 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

So if you would like integer values with one decimal place resolution, you would 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.
