Chris Elston Posted December 7, 2007 Report Posted December 7, 2007 View File Temperature Trend Direction Flag Operator wanted an easy way to tell if temperature was rising or falling in the tank. So without having to setup a full blown trend chart I came up with the "trend flag". If the flag or integer "Tank_1_Resin_Temp_Trend" was equal to "1" then the temperature is rising. If the flag is "0" then the temperature is falling. Easy fix with one rung. Submitter Chris Elston Submitted 12/07/2007 Category PLC Sample Code
