1.0     DLPCI General Operation & Applications

The DLPCI continues the functionality of the current DLPC/DLPC104 product line. It offers both the Allen Bradley DH-485 or DH+ support.

The DLPCI has two communication ports. Channel A is designed to connect to you industrial network, either A-B’s DH+ or DH-485 networks. Channel B is used to connect to your serial DF1 protocol.

Configuration of the operating parameters is done quickly and easily by the DL32 configuration software shipped with the unit or available on the Equustek Website.

Currently there are two standard DLPCI products available to allow access to A-B’s DH-485 and DH+ network. Contact Equustek Solutions to see if the DLPCI is the correct device for your communication needs.

The DLPCI-DF1 is a two port device that allows your DF1 driver to communicate with ones on an Allen Bradley DH-485 or DH+ network. The DF1 model is a direct replacement for the 1770-KF3 for DH-485 and 1770-KF2 for DH+ and allows your PCs access to any node on the corresponding Allen Bradley network.

Debug Mode
Starts up a DLPCI internal Debug mode that can be used by trained personnel to debug problems and check hardware configuration and operation.
Firmware Version
Once selected the current DLPCI model and version numbers will be displayed. Can be used to check the correct firmware was burnt into the Flash or if the DLPCI has the most up to date firmware in the Flash.
Does a soft “software” reset of the unit to put it online.

5.0     Switch and LED Indicator Functions

5.1     Switch Functions
The Configure pushbutton takes the DLPCI out of On-Line operation mode and puts it in the BIOS Manager mode. The BIOS Manager mode also allows for configuration parameters to be downloaded from or uploaded to the Windows based configuration software (DL32). When this mode has been entered the STATUS LED will be RED and BUS LED will be Green while NET LED will be off. To put the unit back On-line use option 7 from the BIOS menu or can power off then on the PC.

5.2     Indicator Functions
5.2.1     Power-Up and Reset Sequence
On Power-up the DLPCI executes a self diagnostic check-up or the ram and flash firmware. The correct LED indicator sequence to show the DLPCI is functioning properly is as follows: After all LEDS go out.

RED for 0.5 seconds
Green for 0.5 seconds
Green for 0.5 seconds
After this sequence the DLPCI goes into the On-line mode of Operation. The LED indicators will behave in the certain way defined by the DLPCI model used. Most likely all LEDS will be off waiting for communication on its channels.

5.2.2     Normal On-line Operation
The following is a description of the normal operation of the Channel LEDs on the DLPCI.

Description of Operation
Solid Green when on line on DH+ or Flashing on DH485 Network.
Flashes or solid Green if there is activity of the DF1 side.
Flashes RED for 0.5 seconds if a NAK is received or transmitted in DF1 protocol. Will also flash RED if duplicate node address on DH+/DH485 exists.

5.2.3     On-Line, Power-Up and Reset Errors
The following table describes the meaning of LED patterns if the internal diagnostic tests detect an error on Reset/Power-Up.

Appendix A :     Installing the RS232 Serial Driver For the DLPCI

A1: DLPCI Windows XP 32 bit driver installation After installing the card in any PCI bus when you power up the PC it will come up with Found new hard ware wizard as shown, select No, not this time as shown.

Then select Install from a list or specific location.

Select Don’t search, I will choose the driver to install.

Select Ports(COM & LPT) as shown below.

Here you click on Have a Disk.

Now brows to where you have the diver saved.

Select the latest driver as shown below.

Here click on OK

You will see under Model the DLPCI Interface Card click on it to highlight it, and then click on Next.

Click on Continue Anyway

Click on finish.

In the Device manager, check the comport number for the DLCPI and remember it to use in configuring the Allen Bradley DF1 driver.
You can change the port number for any comport number that is available on your PC.

Close and restart your PC.

A2- Equustek DLPCI ( Allen BradleyDF1 to DH+ / DH485 ) PCI Bus Card with Windows 7
DLPCI Windows 7 32 bit driver installation.
If windows set to automatic windows driver installation, and after the DLCPI is installed in the PC the DLPCI driver installation will fail, so you need to go to device manager, you will find the failed device with yellow exclamation mark (Other PCI Bridge) as shown below.

Right click on Other PCI bridge device and click on update driver, then click on Browse my computer for driver software.

It will come up with the windows shown below scroll down, select Ports(COM & LPT) and click Next.

From the window shown below make sure (Standard port Types) and (Communications Port) are selected and then click on Have Disk.

It will come up with a window where you can browse to the location of the driver file saved on your hard drive or CD.

Here it will show the DLPCI Interface card highlight it, and click Next.

To continue installing the driver, click on Install this driver software anyway.

Wait for the driver to complete installation.

Here you will see the successfully completed message click on Close.

Go back to your Device Manager under Ports ( COM & LPT) you should see the DLPCI Interface card with specific COM port number that you will use with your Allen Bradley DF1 driver.

Now you can restart your PC and if you encounter any issue just shut down the PC and move the DLCPI to another PCI slot it will resolve that issue if any exists.

That will complete the installation of the WIN7 PCI driver for the card.
Again please note this serial port number is used for setting up the DF1 drive, later on.

Appendix B :     DLPCI Configuration:

To configure the DLPCI you need the DL32 configuration software installed. Insert the Equustek CD. The selection screen should start up automatically. If it does not start automatically, select Run from the Start Menu and enter “D:\Autorun.exe” where “D” is the drive letter of your CD drive.
