In this example, the Parameter 10 - [Elapsed Run Time] value of 6553.9 Hrs
is read as ‘6553.9’ in Datalink A1 Out (Parameter 310) and Datalink A2
Out (Parameter 311).
Conversion Example:
Parameter 010 - [Elapsed Run Time]
= 6553.9 Hrs
MSW = 0001
hex
= 0001
binary
= 2
16
= 65536
LSW = 0003
hex
=3
Engineering Value = 65536 + 3 = 65539
Parameter 10 Displayed Value = 6553.9 Hrs
Regardless of the Datalink combination, Datalink x1 Out will always
contain the LSW and Datalink x2 Out will always contain the MSW. In the
following example, the PowerFlex 70 drive parameter 242 - [Power Up
Marker] contains a value of 88.4541 hours.
Conversion Example:
Parameter 242 - [Power Up Marker]
= 88.4541 hours
MSW = 000D
hex

LSW = 7F3D
hex
= 32573
Engineering Value = 851968 + 32573 = 884541
Parameter 242 Displayed Value = 88.4541 Hrs
