Will the MATHBIN (IB-501), MATHBCD (IB-521) or MATHR (IB-541) IBoxes support the “^” as a “raised-to” exponent function?
No. This is because this functionality is not supported by the DL PLCs. Remember that IBoxes are not something new, but are actually Ladder macros. Therefore since behind the IBox graphic is simply Ladder Logic, then IBox functionality depends on the Instruction Set of the DL PLC. To do this kind of math would require a BASIC Coprocessor.
