-^ Command ^ Description ^
+Count input events or store and retrieve 16-bit values in order.
-| ''Ictu(id, CU, RESET, PV)'' | Counts ''CU'' rising edges and turns ON at ''PV''. |
-| ''Ictd(id, CD, LOAD, PV)'' | Decrements on each ''CD'' rising edge after ''LOAD''. |
-| ''Ictud(id, CU, CD, RESET, LOAD, PV)'' | Handles increment and decrement together. |
-| ''IgetCount(id)'', ''IsetCount(id, value)'' | Reads or changes the current value. |
-| ''IctudDownState(id)'' | Returns the lower-limit completion state of the Up/Down counter. |
-| ''FIFO(id, IN, OUT, input, output, size, reset)'' | Retrieves the first stored 16-bit data first. |
-| ''FILO(id, IN, OUT, input, output, size, reset)'' | Retrieves the last stored 16-bit data first. |

-===== Command Prototypes =====
+  * [[:en-us_commands:reference:ictu|Ictu()]] — Counts input rising edges and returns ''true'' when the preset value is reached.
+  * [[:en-us_commands:reference:ictd|Ictd()]] — Loads the preset value, then decrements the current value at each input rising edge.
+  * [[:en-us_commands:reference:ictud|Ictud()]] — Handles increment and decrement inputs in one counter.
+  * [[:en-us_commands:reference:igetcount|IgetCount()]] — Returns the current value of the specified counter.
+  * [[:en-us_commands:reference:isetcount|IsetCount()]] — Changes the current value of the specified counter.
+  * [[:en-us_commands:reference:ictuddownstate|IctudDownState()]] — Returns the lower-limit completion state of the Up/Down counter.

+===== Data Buffers =====
-| ''bool'' | ''Ictu(uint8_t counter_id, bool CU, bool RESET, int32_t PV)'' |
-| ''bool'' | ''Ictd(uint8_t counter_id, bool CD, bool LOAD, int32_t PV)'' |
-| ''bool'' | ''Ictud(uint8_t counter_id, bool CU, bool CD, bool RESET, bool LOAD, int32_t PV)'' |
-| ''int32_t'' | ''IgetCount(uint8_t counter_id)'' |
-| ''void'' | ''IsetCount(uint8_t counter_id, int32_t value)'' |
-| ''bool'' | ''IctudDownState(uint8_t counter_id)'' |
-| ''bool'' | ''FIFO(uint8_t fifo_id, bool IN, bool OUT, uint16_t input, uint16_t &output, uint8_t size, bool reset = false)'' |
-| ''bool'' | ''FILO(uint8_t filo_id, bool IN, bool OUT, uint16_t input, uint16_t &output, uint8_t size, bool reset = false)'' |
-''IN'', ''OUT'', ''CU'' and ''CD'' act on rising edges. Use a unique ''id'' for each counter or buffer, and keep ''size'' to the required minimum.
+  * [[:en-us_commands:reference:fifo|FIFO()]] — Outputs the first stored 16-bit data first.
+  * [[:en-us_commands:reference:filo|FILO()]] — Outputs the last stored 16-bit data first.
