Abstract
This document describes a simple method of acknowledging alarms in a Siemens text OP (operator panel with display and keypad). These OPs include the OP20, OP5, OP15, OP7, or OP17. OP "alarms" are an easy method of displaying and acknowledging faults. This version was written for a Siemens S5 PLC.
For an S7 version, see PLC Archive:Alarm Acknowledge - S7 version.
