DL2000-User Manual

1.0 DL2000 General Operation & Applications

The DL2000 communication controller is a 110/220V AC powered freestanding CSA/UL approved which provides a RS232/RS422/RS485 serial link to A-B’s DH+ or RIO networks.

The DL2000 has two communication ports. Channel A is designed to connect to you industrial network, either A-B’s DH+ or RIO networks. Channel B is used to connect to your serial device, such as PC’s, HMI/MMI’s or PLC’s. The protocol used depends on which flavour (model) of the DL2000 you have ordered.
Channel B has the capabilities of RS232C, RS422, and RS485.

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

Currently there are three standard DL2000 products available to allow access to A-B’s DH+ network; also many other customized ASCII protocol interfaces have been done. Contact Equustek Solutions to see if the DL2000 is the correct device for your communication needs.

The DH+ version of the DL2000 product line is as follows :

The DL2000-CMX is a two port device that bridges your Modicon Modbus devices to ones on a DH+ network. The Modbus model can either be used as Modbus Master or Slave as well as having both Modbus ASCII and RTU protocols.

The DL2000-KFX is a two port device that allows your DF1 devices (either Full or Half Duplex protocols) to ones on a DH+ network. The DF1 model is a direct replacement for the 1770-KF2 and allows your PCs or Laptops access to any node on the DH+ network.

The DL2000-ASM interfaces Serial ASCII devices (Scanners/Printers) to SLC’s or other devices on A-B's DH+ network.

2.0 Hardware Specifications

The DL2000 Hardware Platform has the following specifications.

2.1 Operating Specifications:

CHA can be configured for DH+/RIO speeds of 57.6, 115.2 and 230.4 KBaud.

CHB has full RS232C, as well as both RS422 4 wire and RS485 2 wire modes. CHB has the ability of being configured with asynchronous speeds upto 57.6 KBaud. CHB has two physical connections, a DB 25 Male and a configurable 5 pin phoenix (jumper configurable for RS232/RS422-RS485).

Currently industry standard protocols of DF1, Modbus, and ASCII are the supported. Many custom protocols for different Variable Speed Drives, Weight Scales and other OEM devices have been implemented.

ERASING FLASH, PLEASE WAIT...

SEND FIRMWARE TEXT FILE NOW...

Once the message to send the firmware appears then either click on the “Burn Flash System File” button to select the .txt file to send, or send the Text File under HyperTerminal.
Wait for a “FIRMWARE LOAD/BURN COMPLETED A-OK!” message to appear.

3. Memory Dump

This is used to display the RAM memory of the DL2000. This should only be done after contacting Equustek Solutions to debug problems.

4. Off-Line Diagnostics

Starts a series of tests to test the DL2000’s hardware and should only be done if instructed so by trained personnel.

5. Debug Mode

Starts up a DL2000 internal Debug mode that can be used by trained personnel to debug problems and check hardware configuration and operation.

6. Display Firmware Version

Once selected the current DL2000 model and version numbers will be displayed. Can be used to check the correct firmware was burnt into the Flash or if the DL2000 has the most up to date firmware in the Flash.

7. Go Online

Does a soft “software” reset of the unit to put it online.

5.0 Switch and LED Indicator Functions

5.1 Switch Functions

The Reset pushbutton will perform a complete hardware reset of the DL2000. It is identical to a complete power cycle and will cause the DL2000 to go through its LED start-up sequence as defined in Section 2.3.

The Configure pushbutton takes the DL2000 out of On-Line operation mode and puts it in the OFF-LINE Flash Manager mode. The OFF-LINE FLASH Manager mode also allows for configuration parameters to be downloaded from or uploaded to the Windows based configuration software (DL32-FREEstanding). When this mode has been entered the ERR and CHAN 2 OUT LED’s will be on. To put the unit back On-line it is necessary to either press the Reset or cycle the power supplied to the DL2000.

5.2 Indicator Functions

5.2.1 Power-Up and Reset Sequence

On Power-up or after the Reset button has been pressed the DL2000 executes a self diagnostic check-up or the ram and flash firmware. The correct LED indicator sequence to show the DL2000 is functioning properly is as follows: After all LEDS go out.

LED: STATUS
PWR: Green Continuously
ERR: Green for 0.5 seconds
CHAN 2 OUT: Green for 0.5 seconds
CHAN 2 IN: Green for 0.5 seconds
CHAN 1 OUT: Green for 0.5 seconds
CHAN 1 IN: Green for 0.5 seconds

After this sequence the DL2000 goes into the On-line mode of Operation. The LED indicators will behave in the certain way defined by the DL2000 model used. Most likely all LEDS will be off except the CHAN 1 IN LED will be on indicating the unit is on a valid DH+ or RIO network.

5.2.2 Normal On-line Operation

The following is a description of the normal operation of the Channel Leds on the DL2000. Custom products operation will differ than the following:

LED: Description of Operation
PWR: Green Indicates Power is being supplied to the DL2000.
CHAN 1 IN: On when a specific message is directed to PORT A.
CHAN 1 OUT: On when a specific message is directed out PORT A.
CHAN 2 IN: On when a specific message is directed to CHB (Port B or B’).
CHAN 2 OUT: On when a specific message is directed out CHB (Port B or B’).
ERR: Flashes RED for about 0.5 secs when a NAK (Negative Acknowledgement) is received on CHB or all transmit and receive buffers are full. Will also flash at approximately 1Hz when a duplicate DH+ node is detected.

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.

LED Pattern: Description of Problem
ALL LED’s Flashing ON & OFF: The flash has not be burnt properly and the A-OK was not transmitted. Please reburn the flash with the correct text file. Contact Customer Support for help.
ALL LED’s ON Solid: The OFF-LINE FLASH has been corrupted. A new Flash Chip has to be supplied by the factory. Please contact Customer support.
Start-up Sequence keeps repeating.: The DL2000 EEPROM is corrupt.. Please Restore to Factory Settings (See Section 1.1) and then reconfigure the unit.

5.2.4 Off-Line Modes

The following table describes the meaning of LED patterns in the different Off-Line modes of operation.

LED Pattern: Description of Operation
CHAN 2 OUT & ERR: OFF-LINE FLASH Manager/Configuration Parameter
Download/Upload and Hardware Diagnostics Testing Mode
CHAN 2 IN & CHAN 2 OUT & ERR: Offline Debug Mode

7.0 DL2000 DH+ Networking Applications

7.1 DL2000-CMX – Modbus Master/Slave to interface to DH+

7.1.1 Modbus Master Mode

NOTE:
The Modbus Master can communicate with any Slave device on the Modbus Slave network and any DH+ devices capable of sending PLC3 or PLC5 message commands. Modbus and DH+ addresses must not be duplicated (convert to the same radix) or the Master will receive two responses. The DL2000 can be any station number on DH+ including Station 00 (not used on Modbus).

7.1.2 Modbus Master Mode using MODBUS PLUS VIA BM85 BRIDGE

NOTE:
PLCs and HMI/MMIs etc. on Modbus Plus can be programmed to communicate with PLC5s, SLC5/04s and
HMI/MMIs on DH+, i.e. any devices capable of handling PLC-5 Type message commands.
