Description

• This program illustrates how a SCAL scaling function block can be used to scale a raw analog input value (16-bit integer) into a scaled value (32-bit floating point).

• The SCAL function is executed on every scan of the ladder logic to scale a raw analog input signal from 0-32760 to 0.000-100.00.

• The Register Editor dialog has been pre-configured to display all pertinent registers used in this program.

• The controller type has been pre-selected as SCADAPack.

• The Register Assignment has been pre-configured with the SCADAPack 5601 I/O Module.

• Refer to the "Ladder Logic Function Reference | Ladder Logic Function Reference | Ladder Logic Functions" section of the "TelePACE User and Reference Manual" for information on the SCAL function.
