ABSTRACT:
A computer-implemented method and a computer-readable program for designing software applications for execution in a programmable logic controller includes determining whether a physical input is analog or discrete, and responsive to the physical input being analog, inputting a set of analog parameters, and responsive to the physical input being discrete, inputting a set of discrete parameters, and storing the parameters in a user parameter data table. The method includes executing a programmable logic controller application responsive to a set of user-defined parameters, including reading an input, and determining whether the input is in fault, and, responsive to the input being in fault, performing an operation from a group of operations consisting of an alarm and a shutdown.
