Hi,
Can anyone else try this and tell me what revision you are using if the value is correct.
Subtract
SUB
Source A 1.0 (constant)
Source B .8 (tag)
Result .19999999
Controller Compact Logix 1769-L27ERM-QVFC1B
Revision 30.011
I get the same without the decimal
Subtract
SUB
Source A 1 (constant)
Source B .8 (tag)
Result .19999999
I get the same with Compute
CPT
Dest PercentPerformanceLoss
0.1999999999
Expression 1.0-Performance
I get the same with Compute without the decimal
CPT
Dest PercentPerformanceLoss
0.1999999999
Expression 1-Performance
I understand a decimal being off on multiplication and division but simple addition and subtraction?
The quality guys are going to notice this difference.
