The RSLinx DF1 Driver can be used for point to point communication between your workstation and an Enhaced PLC-5 Processor, SLC 5/03 or higher, or ControlLogix L6x or lower processor. This document assumes that Channel 0 of your processor has been left to factory defaults (DF1, RS232)

1) First connect your Null Modem cable between your workstation and your processor. You will need to know which COM port you are connected to. You can get this information from your Device Manager in Windows. If your COM port is built into your workstation, this will usually be COM 1, but if you have a USB to serial adapter, simply plug in the adapter with Device Manager open (and PORTS expanded), and it will be easy to see which new COM port is added when you plug in your adapter.

Every USB device has a unique hardware id (the combination of VID and PID), so to accomplish the above task my approach is to get COM PORT of USB Serial Device on the basis of VID/PID. The registry of the windows kept the information of the device, so simple logic here to open the windows registry and get the com id.

2) Open RSLinx Communication Server. Ublox software windows 10. RSlinx must first be set up before communication to your processor is possible.

3) Click on “Communication” from the menubar, and choose “Configure Drivers”

2. To manually install the driver, go to the device manager and click on the USB serial device needing the driver. Click on the driver tab. Click on Update Driver. Select the Browse my computer for driver software option, and browse to the driver folder you unzipped. Make sure the Include Subfolders box is checked, and the driver should install.

4) From the “Available Driver Types” pull down menu, choose RS232, DF1 Devices, then hit “Add New”.

5) For this example, the name can be left at default. Press “OK”.

6) Be sure to choose your COM port that you found in Step 1. The communication parameters can be entered manually, but if you are connected to the processor with your NULL modem cable, simply press the “Auto-Configure” button. RSLinx will test the processor for different baud rates, and other settings, until it finds a setting it gets a response on. You will get a message that the autoconfiguration was successful. If you received a message that the autoconfiguration has failed, be sure that you have the correct cable, the processor is powered on, Channel 0 is at factory default setting (DF1), and the correct COM port has been selected, then try the Auto-Confugure button again.

7) You will now see the driver is running. Close the driver configuration screen.

8) Now lets, verify communication by opening the RSWho Screen within RSLinx. This can be found under the “Communication” menu, or you can hit the RSWho Icon on the standard toolbar.

9) Click your DF1 Driver on the left side of the RSWho Screen. The devices you are communicating with will appear on the right.

To go Online with the processor, you must go to RSLogix at this point

• The Legacy USB Driver is used only for the black communications interface, which requires a TTS USB to Serial adapter. The blue and green communications interfaces do not use an adapter, and this driver is not required.

Configuring the USB Driver

NOTICE:
Always install the USB drivers prior to connecting the USB adapter to the PC for this first time. This way, when the USB adapter is first connected it will automatically be detected and will not prompt you for a driver installation disk.

The Legacy USB drivers can be downloaded by clicking the link above titled 'Legacy HD04 USB Driver.' Alternately, these are available from the FTDI website at http://www.ftdichip.com/FTDrivers.htm. Select the VCP (Virtual COM Port) driver type for downloading.

Installing the USB Driver:
After the driver has been downloaded and saved, right-click on the file and select 'Run As Administrator'. This will launch the driver installation program. Follow the on-screen instructions to complete the install.

Determining the USB COM Port Number:
It is necessary to know which COM port the driver has assigned to the USB adapter in order for the legacy MasterTune and Datamaster products to communicate. In some cases, it will be necessary to reassign the COM port to be between COM1 and COM16. The following sections show how to do this using Device Manager.

Windows XP Com Port Reassignment:
NOTICE: You must be logged in as an administrator and the USB adapter must be connected to the PC in order to perform the following configuration.

Invoking Device Manager:
To launch device manager in Windows XP, go to Start - Settings - Control Panel and click on the System icon. This will open the Systems Properties dialog. Select the Hardware tab and then click the Device Manager button.

Tip: A shortcut to access Device Manager is to open devmgmt.msc from the Start - Run dialog:

This will bring up the device manager dialog. Go to the section labeled Ports (COM & LPT) and click on the '+' symbol to view the port assignments:

Star micronics printer utility. In this example, there are a total of three COM ports shown, COM1, 11, and 8. The USB adapter COM port will be labled as a USB Serial Port. Make a note of the USB Serial Port COM number; you will need it when first running MasterTune or DataMaster.

Changing the COM port assignment:
In this case there are two USB serial ports, COM11 and COM8. If the COM port number is greater than COM16, it must be reassigned to a lower number. The following example shows how to reassign COM11 to a new COM port number.

To reassign the COM port number, double click on the USB Serial Port selection to be changed. This will bring up the driver configuration dialog:

Select the Port Settings tab, then click the Advanced button: This will bring up the Advanced Port Settings dialog. In this example, note COM1 through COM10 are already 'In Use' by other devices.

The TTS USB port MUST be assigned between COM1 and COM16. If all these port assignments are already in use, make a new selection between COM5 and COM16. Avoid COM1 - 4 which are usually the Laptop hardware such as IR, Modem, or BlueTooth connections. - You will receive the following warning:

Click Yes to accept the new assignment. This will generally not cause any problem - however the selection can be easily changed at a later time if necessary.

Make a note of the port number you selected, and click OK to apply the changes. When you open MasterTune or DataMaster and select the serial COM port, use this port number.
