This document describes a simple method of acknowledging alarms in a Siemens text OP (operator panel with display and keypad). These OPs include the OP7, and OP17. OP "alarms" are an easy method of displaying and acknowledging faults. This version of the subroutine is for a Siemens S7-22x and was translated from an older S5 function block which has been used in numerous applications.
