Ladder Logic Natural Log / Log Functions

Takes the natural log of value in the source and stores it in the destination

Example

Equation: F8:9 = ln (20)

Ladder Logic Solution:

Note

• If an overflow is generated or an invalid source is detected, a minor error will be generated. This error should be cleared to avoid a major error.

LOG - Log to the Base 10

Takes the log base 10 of the value in the source and stores the result in the destination.

Example

Equation: F8:11 = log (10)

Ladder Logic Solution:

Note

• If an overflow is generated or an invalid source is detected, a minor error will be generated. This error should be cleared to avoid a major error.
