DL3500 General Operation & Applications

DL3500 General Operation & Applications

The DL3500 continues the functionality of the DL2000/DL3000 product line. It offers both the new addition of DH485 as well as a plug and play USB interface. As well as having the DH+ and 232/422/485 capabilities of the DL3000. Two DL3500 Models will also allow Bridging between DH+ and DH485networks. New is the ability to power the DL3500 from the USB communication link, removing the sometimes cumbersome procedure of location an AC or DC power supply when using laptops or PC’s inthe field.

The DL3500 has two communication ports. Channel A is designed to connect to you industrial network,either AB DH+ or DH485 networks. Channel B is used to connect to your serial or USB device, the protocol depends on which flavour (model) of the DL3500 you have ordered.

Channel B has the capabilities of RS232C, RS422, RS485 and USB 2.0. Configuration of the operating parameters is done quickly and easily by the DL32 V3.X windows based software shipped with the unit or available on the Equustek Website. Currently there are three standard DL3500 products available to allow access to A-B’s DH-485 and DH+ network.

Many other custom ASCII and serial protocols have been implemented to Both DH+ and DH-485 on the DL3500 platform. Contact Equustek Solutions to see if the DL3500 is the correct device for your communication needs.

The DL3500 has all three models below available in DH+ and DH485 flavours:

The DL3500-Modbus is a two port device that bridges your Modicon Modbus devices to ones on an Allen Bradley DH485 or DH+ network. The Modbus model can either be used as Modbus Master or Modbus Slave as well as having both Modbus ASCII and RTU protocols.

The DL3500-DF1 is a two port device that allows your DF1 devices (either Full or Half Duplex protocols) to ones on an Allen Bradley DH485 or Allen Bradley 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 or Laptops access to any node on the corresponding A-B network.

The DL3500-ASCII interfaces Serial ASCII devices (Scanners/Printers) to SLC’s or other devices on an Allen Bradley DH485 or DH+ network. The DL3500-DF1/DH+ or DH485 interfaces your DF1 devices (either Full or Half Duplex protocols) to ones on either an AB DH485 or DH+ network. The DL3500 comes with both networks available with only using the software configuration program to switch between the DH485 and DH+ networks

 

DL4000 General Operation & Applications

The DL4000 hardware platform was designed to be used as a smart Serial to Serial converter. It comes in a DC powered Din-Rail Mountable compact cabinet for ease of portability and installation. Standard protocols such as Modicon Modbus and Allen Bradley’s DF1 exist already. Other protocols and operations are easily programmed per customer’s requests.

The DL4000 has three serial channels, CHA, CHB, and CHC for intermixing protocols and communication standards. RS232C, RS422 and RS485 are available on CHA and CHB, while CHC only does RS232. Configuration of the operating parameters is done quickly and easily by the DL32 V3.X for all DL4000 models except DL4000-DMX use EQ32, both EQ32 and DL32 are windows based software shipped with the unit or available on the Equustek Website. Currently there are five standard DL4000 products available and many other customized ASCII protocol interfaces have been done.

Contact Equustek Solutions to see if the DL4000 is the correct device for your communication needs.

The DL4000-DMX is a two port device that bridges your Modicon Modbus devices to ones using the DF1 protocol. The DMX can either be used as Modbus Master or Slave as well as having both Modbus ASCII and RTU protocols.

The DL4000-DFX is a three port DF1 device. This will allow Two DF1 devices to talk to one CH0 of a PLC or SLC. The ability to intermix Half-Duplex and Full Duplex, or RS232 and RS422 greatly improves the effectiveness of the PLC’s CH0 programming port

The DL4000-MMX allows Modbus RTU devices to communicate with multiple Modbus ASCII devices. The DL4000-DAS interfaces Serial ASCII devices (Scanners/Printers) to A-B’s DF1 protocol.

The DL4000-MAS interfaces Serial ASCII Scanners to Modicon’s Modbus Protocol. The DL4000-MAS acts as a Modbus Master device and writes the ASCII data to a specific register in a specified slave device.

Using Wonderware’s ABTCP driver with the EQ7000

Wonderware’s ABTCP IO Server is capable of reading and writing data to devices on the DH+ using the EQ7000. Before any data can be read or written, a new local host must be created in the host file and a topic must be defined in the ABTCP IO Server.

Configuring the Hosts File The hosts file contains the names of local hosts and the IP addresses that are assigned to them. You must add a new entry to the hosts file with the IP address of the EQ7000. Below are the steps to adding a new entry to the hosts file.

1. Locate and open the hosts file. The host file can be found in the following directory. C:\WINDOWS\system32\drivers\etc

2. Open the hosts file using a text editor like Notepad. You will see the following.

3. Add a line at the end of the file specifying a new host name and IP address and then save the file. In the example below, the host name EQ7000 is added and has an IP address of 192.168.2.75.
