Modbus RTU - Client Setup
Modbus RTU - Client Setup — Configures one Modbus RTU
client node
Library
Simulink Real-Time - Speedgoat
Description
The Setup block configures one Modbus RTU Client node, which can be connected to
Modbus RTU Servers and enables the Send and Receive blocks to exchange data on the
serial line. Every Modbus RTU Client Setup block in the model requires a runtime
license.
For serial interface configuration, the Modbus RTU Client Setup block requires the
Setup block of the corresponding serial I/O module to be placed in the model. If you
use an IO503, for example, add an IO503 Setup block to the model and make sure both
Setup blocks have the same Module ID.
Ports
This driver block has no input or output ports.
Parameters
Physical Layer
-
Serial Interface
Select the type of the serial interface you want to use for Modbus
communication. The list consists of supported serial I/O modules.
-
Module ID
Enter the Module ID of the related serial module's Setup block.
-
Channel
Enter the channel number of the serial I/O module to which you want to
assign the Modbus RTU client node.
Parameters
-
Interface ID
The Client Setup block defines one Modbus RTU client interface bound
to a specific serial channel. The interface ID is used to assign Setup,
Send and Receive blocks to that interface. Interface IDs range between 0
to 65535 and must be unique along all Modbus RTU Client and Server setup
blocks in a model. You can define multiple clients by placing multiple
Setup blocks in your model with unique interface IDs for each
client.
-
Automatic Interface ID
The automatic interface ID checkbox enables the automatic generation
of a unique interface ID, based on the above physical layer selection.
-
Response Timeout
Specifies the time in milliseconds that the client should wait for a
response from the server before sending another request. The response to
the initial request is ignored if it is received after the time has
elapsed.
-
Sample Time
Defines the base sample time at which this driver block gets its sample hit. This
parameter can also be set to -1 for inherited
sample time. The units are in seconds.
