Overview
This library exposes a block interface for the Modbus protocol. This protocol is useful for many industrial application. The library handles many of the details under the hood, so the end-user can configure which modbus registers to read (master) or to write (slave). The library abstracts the details of the protocol into a simple block interface consisting of just a handful of blocks and configuration scripts.
Blocks
| Block | Description | Appearance |
|---|---|---|
Modbus Master |
This block acts as a Modbus master on a serial bus. |
 |
Modbus Slave |
This block acts as a Modbus slave on a serial bus. |
 |
Modbus Slave Error |
This block will send a MODBUS Error Response. |
 |
Modbus Slave Response |
This block is used to package and send a response to a request. |
 |
Details
Modbus specification may be downloaded from (modbus.org): PI_MBUS_300
Modbus Master currently supports the following commonly used service(s):
- 03 Read Holding Registers
Modbus Slave currently supports the following commonly used service(s):
- 03 Read Holding Registers
- 06 Preset Single Register
This library may be used on Raptor targets which expose a serial (RS232/RS485) interface such as the DISP-IMX286 (VEECAN) targets.
