 ===== Script Tag Templates =====
-Script Tag Templates are pre-configured to perform a specific function.
+A number of pre-configured script tags exist to perform the following functions:
-The following templates exist:
 ==== Calculations ====
+  * **Accumulator Calculator** \\ Calculates the accumulated result of a monitored process tag for a given period (e.g. a day).
+  * **Aggregation Calculator** \\ Periodically calculate an aggregation of a process tag.
   * **Average Calculator** \\ Periodically calculates the average value of a process tag.

   * **Delta Calculator** \\ Calculates the delta between the value of two input tags.
-  * **GasVelocityCalculator** \\ Calculates gas velocity using flow rate and pressure.
+  * **Delta with Offset Calculator** \\ Calculates the delta between the value of two input tags, then applies an offset.
+  * **Energy Based Availability Calculator** \\ Energy-Based Availability (EBA) is the ratio of actual to expected energy production.
+  * **Gas Velocity Calculator** \\ Calculates gas velocity using flow rate and pressure.
+  * **Normalized Deviation Calculation** \\ Calculates the normalized deviation of a process value.
+  * **Ratio Calculator** \\ Calculates the ratio and between two input tags.
+  * **Time Based Availability Calculator** \\ Time-Based Availability (TBA) is an energy expression denoting the ratio of a time-period (e.g. a day) when power is available. It does not discriminate the cause of downtime (e.g. a deliberate stop for maintenance, no/low wind conditions).
+  * **Time Based Delta Calculator** \\ Monitors the rate of change of a process tag over a time period.
+  * **Turbine Status** \\ A turbine has three basic power-production states: 1. Power; 2. No Wind; 3. No Power.
+  * **Turbulence Intensity Calculator** \\ Turbulence Intensity (TI) is a measurement of wind speed turbulence. It is the ratio of wind speed StdDev to Mean.
+  * **Turbulence Intensity Forecast Calculator** \\ Turbulence Intensity Forecast (TI) is an measurement of wind speed turbulence derived from forecasted Wind and Gust Speed (rather than observed wind speed variance).
+  * **Unit Converter** \\ Convert process value from one unit to another.
 ==== Sensor Quality Checks ====

   * **Frozen Signal Detection** \\ Script tag that periodically ensures that newer values are being received for a tag.

   * **Fleeting Excursion Monitor** \\ Script tag template for monitoring sensors such as acoustic sand probes that can generate fleeting excursions.
+  * **Hi/Lo Limit Monitor** \\ Performs a Hi/Lo limit monitor check.
   * **Limit Monitor** \\ Script tag that periodically monitors a process tag value against a limit using MIN/MAX aggregated data. \\ //Use the FleetingExcursionMonitor template if you require a high degree of accuracy.//
+  * **Limit Monitor 1 Precondition** \\ Limit monitor that will only trigger or reset an excursion event if a precondition tag value check is met.
+  * **Limit Monitor 2 Precondition** \\ Limit monitor that will only trigger or reset an excursion event if two precondition tag value checks are met.
+  * **Limit Monitor 3 Precondition** \\ Limit monitor that will only trigger or reset an excursion event if three precondition tag value checks are met.
+  * **Logic Gate Alert** \\ An alert that can be used to summarise the status of multiple alerts using an AND or OR operator.
   * **Time Based Delta Monitor** \\ Monitors the rate of change of a process tag over a time period.
+  * **Value Change Monitor** \\ Monitors a tag and emits an event every time the value of the tag changes.
