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.
