Description
This section describes how to configure the PROFIBUS DP network.
GSD File
To set up PROFIBUS communication, you must import the device description files of
PROFIBUS slaves (GSD file) into your PROFIBUS Master configuration tool or PLC
programming tool (refer to Step 7). You can download the GSD file HIL_0B69.GSD of the default IO642 here.
If you use warmstart parameters to simulate a PROFIBUS slave of a different
vendor, you must import the GSD file of that particular slave into your Master
configuration tool. The GSD file is generally available on the vendor's website.
I/O Module configuration from Simulink
The warmstart mode allows the PROFIBUS DP Slave to be configured in Simulink using
the Setup driver block.
This approach offers more options than Sycon.net and rules out having to generate
and handle configuration files.
I/O Module configuration with SYCON.net
During initialization of the real-time application, the IO642 Setup block reads a
configuration file from the hard drive of the target machine and configures the
PROFIBUS DP protocol stack. Use the SYCON.net configuration tool to create such a
file.
![[Tip]](images/tip.png) | Tip |
|---|
Download the SYCON.net configuration tool from the Speedgoat Customer Portal.
Login to your Speedgoat account. In the Downloads section,
navigate to Software and click SYCON.net (v1.400 Build 170125). |
![[Note]](images/note.png) | Note |
|---|
Only SYCON.net V1.400 Build 170125 has been
tested. There is no guarantee therefore that other versions will work with the
Speedgoat I/O Blockset. |
In addition to this short introduction, please read the SYCON.net help
documentation for detailed information about how to set up a PROFIBUS DP device and
export the module configuration file.
Open SYCON.net and locate the "CIFX DP/DPM" PROFIBUS DPV1 Master. Drag it
to the blue line in the main panel. This creates a magenta colored PROFIBUS
line.
Locate the "CIFX DP/DPS" PROFIBUS DPV1 Slave from the "Gateway /
Stand-Alone-Slave" section and drag it to the PROFIBUS line in the main
panel.
Open the Configuration window from the slave's context menu.
Under Configuration/Modules, define the I/O data modules to be supported
by the slave by appending them to the "Configured Modules" list.
| Note |
|---|
The Input modules are actually the outputs of the slave and vice
versa. It is named from the master's point of view. |
The slave address is set to "2". This can be changed in the station table
of the master device's configuration.
Apply the configuration and close the windows. Right-click on the Slave
icon and select Additional Functions, Export, DBM/nxd
Select a name for the file, for example: my_slave.nxd. Save the file in
your current MATLAB workspace.
In MATLAB, use the following script to load the configuration and the
firmware to the target machine:
IO642 = sg_IO64X_struct();% Create default structure
IO642.protocol = 'IO642'; % Protocol Speedgoat ID
IO642.cardid = '1'; % Module ID as defined in the model
IO642.configfiles = '1'; % Number of configuration files
IO642.configPath = ''; % Absolute path or '' for current dir
IO642.configfile1 = 'my_slave.nxd';% Name of first configuration file
sg_IO64X_loadconfig(IO642);
Configure the driver blocks according to the configuration defined in
SYCON.net by specifying the corresponding amount of bytes in the "PBS
Receive" and the "PBS Send" block.
When you download the model, the firmware and configuration files are
loaded to the IO642 I/O module.
Front Plate Description
IO642 PCI and PCIe modules
The rotary switch has no functional role.
IO642 mPCIe module
Note that in some real-time target machines,
the mPCIe module is reversed; that is, the Error LED appears on the right.
IO642-32 Multi-node simulator
The IO643-32 simulates 32 PROFIBUS Slave nodes. Each node has two LEDs that
indicate the communication status.
