Configuring Rules

The Rules feature enables you to configure periodic if-then-else rules used to process Email, SNMP Traps, Combination, FTP, Output and Report to File actions. Using the Rules feature, you can also edit, test and delete an existing rule. The system can handle up to 25 rules.

The rule shown in Figure 4.2 is used to control a fan connected to a digital output. The value in the Value to test field (Temp1) is a calculation that will equal 1 if an analog input exceeds 85 degrees F. If the analog input falls below 85 degrees F, the Temp1 calculation will equal Ø. This rule scans the Fan_ Temp calculation every 60 seconds and either turns the output connected to the fan on (Temp1 = 1) or off (Temp1 = Ø). An output action is used to toggle the digital output.
