IF Conditions
IF conditions are events that trigger the THEN/ELSE actions. In the IF column, you can set up to 3 conditions
that must be satisfied for the actions under the THEN/ELSE columns to take place. As soon as the IF conditions
are satisfied, the specified THEN/ELSE action is performed. For example, an alarm can be activated when a
door is opened. Use the dropdown menus to specify the conditions and units of measurement (e.g., DI-0=OFF).
DI
DI refers to the status of a digital input channel. Edge detection can be used to refine the conditions. For
example, the condition DI-0=OFF is satisfied for as long as DI-0 remains off. The condition DI-0=ON to OFF,
however, is only satisfied the instant the DI-0 turns off. The transition of the status change can also be
indicated using the Change operator. In this case, it will trigger the related action depending on whether it is
ON-to-OFF or OFF-to-ON. Set the IF condition to DI and click the property button to enter the DI Settings
window.
AI
AI refers to the readings of an analog input channel. An analog input value is specified to trigger an action.
Units of the value are defined by the selected analog modes (voltage or current), or the scaling results. For
example, AI-0 > 15 mA could represent the highest allowed level of a water tank.
RTD
RTD refers to the readings of an RTD channel. RTD channels are used to measure temperature. For example,
an alarm could be triggered when the temperature reaches 40°C (RTD-0 > 40). Celsius or Fahrenheit
temperature units can be selected in the I/O Configuration tab after logging in as administrator.
TC
TC refers to the readings of a TC channel. TC channels are used to measure temperature. For example, an
alarm could be triggered when the temperature reaches 500°C (TC-0 > 500). Celsius or Fahrenheit
temperature units can be selected in the I/O Configuration tab after logging in as administrator.
