 The speed limit signs must be placed next to the track so that they can

+## Command Interface
+
+### Techage ICTA Controller
+
+The ICTA Controller support the conditions:
+
+- "read cart state" (function returns "stopped" or "running")
+- "read cart location" (function returns the distance or the station/buffer name)
+
+See help page of the ICTA controller block.
+
+### Techage Lua Controller
+
+The Lua controller support the functions:
+
+- `$cart_state(num)`  (function returns "stopped" or "running")
+- `$cart_location(num)`  (function returns the distance or the station/buffer name)
+
+See help page of the Lua controller block.
+
+### Cart Terminal
+
+The Cart Terminal has a Techage command interface with the commands:
+
+| Command    | Data       | Description                                             |
+| ---------- | ---------- | ------------------------------------------------------- |
+| `state`    | \<cart-ID> | Returns `unknown`, `stopped`, or `running`              |
+| `distance` | \<cart-ID> | Returns the distance from the cart to the Cart Terminal |
+
+### Beduino Controller
+
+The Cart Terminal has a Beduino command interface with the commands:
+
+| Command  | Topic | Data      | Response   | Description                                             |

-###  event
-
-Every signal that is sent to an I/O module triggers an event on the controller.
-Events can be queried using the `event()` function.
-If the function returns the value `1`, one or more signals have been received.
-Calling `event()` resets the event flag.
-
-```c
-event()
-```
-
-### read
-
-Read a value from a remote techage block.
-
-- *port* is the I/O module port number
-- *cmnd* is the command, like `IO_STATE` (see example code  "ta_cmnd.c")
-
-```c
-read(port, cmnd)
-```
-
-### send_cmnd
-
-Send a command to a techage block (see [commands](https://github.com/joe7575/beduino/blob/main/BEPs/bep-005_ta_cmnd.md)).
