Returns Error_ExpressionEval("Error executing script for runScript() expression:ByteUtil.double_le2")
on the tag with the script "runScript("ByteUtil.double_le2", 0, {[~]1_IR30001})". I didn't change the tag name but the OPC address is ns=1;s=[RedMeter]1.IRI_6430001
The tags also return an Error_TypeConversion with the data type as Integer. It returns a number when set to Long, Float, or Double though.
I may have forgotten to save after entering the new function. It isn't giving an error now but the value is still extremely small. I'm still playing with it to see if I can bring in another register.
The IRI_64 is set as a Long currently and the expression tag is a Double.
My brain is embarrassing mush this morning. I can't be trusted with bit banging right now.
Try this:
def double_le2(value):
from java.lang import Double
b0 = (value >> 56) & 0xFF
b1 = (value >> 48) & 0xFF
b2 = (value >> 40) & 0xFF
b3 = (value >> 32) & 0xFF
b4 = (value >> 24) & 0xFF
b5 = (value >> 16) & 0xFF
b6 = (value >> 8) & 0xFF
b7 = (value >> 0) & 0xFF
return Double.longBitsToDouble(b0 | (b1 << 8) | (b2 << 16) | (b3 << 24) | (b4 << 32) | (b5 << 40) | (b6 << 48) | (b7 << 56))
Result should be 3.99 with the Long value from your screenshot.
My HERO!!!
Ooph, insult to injury, making it harder on myself all along:
def double_le3(value):
from java.lang import Long
from java.lang import Double
return Double.longBitsToDouble(Long.reverseBytes(value))
Stepping away from the computer before I do more damage 
That worked as well. Time for more coffee. Thanks again @Kevin.Herron
