Description
This block acts as a Modbus Slave on a Serial bus. The block processes the Serial data and triggers port one on a valid read holding registers request or a valid write holding register request.
Outputs
| Output | Type | Description |
|---|---|---|
| Read()/Write() | trigger | This port contains a vector of triggers, trigger [0] is the trigger to indicate that a holding register read has been requested. Trigger [1] is fired when a holding register write is requested. |
| Command | uint8 | The numeric command, 03 for read 06 for write. |
| Register Address | uint16 | The address of the register being requested. |
| Data | uint16 | For a read this is the number of registers to read. For the Write command this is the data to be written to the register. |
Parameters
| Parameter | Type | Description |
|---|---|---|
| Serial Bus Name | String | The name of the serial bus that should be utilized. |
| Data Requests | String | A list of data request that should be requested. See: modbus_requests_example.m for the format. |
| Use Inputs | checkbox | If checked the block will use input ports for the data requests. |
