A controller having logical inputs and outputs and physical options for input and output connections that may be determined at the time that the controller is shipped from a factory. However, after release of the controller from the factory, an end user may have the flexibility to map logical inputs and outputs to physical inputs and outputs, respectively, in any manner as desired. This flexibility may result in optimal use of a limited number of input/output terminals and any available network variables to reduce controller complexity and costs. |
