Abstract
This document describes a simple method of determining which is the current screen displayed on a Siemens text OP (operator panel with display and keypad). These OPs include the OP20, OP5, OP15, OP7, or OP17. It is often convenient to determine this screen number in order to limit specified actions to when a particular screen is selected by the operator. This version was written for a Siemens S5 PLC.
