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.
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. Both CRC 16 and BCC error checking can be implemented; custom error checking can be added at the customer’s request.
Simple Parameter Configuration using menu driven Windows (95/98/ME/XP/NT/2000) based Program via RS-232 Cable.
Configuration and Reset Pushbuttons to setup online configuration parameters and do a full Hardware Reset
Operating Parameters are stored in Non-Volatile Serial EEPROM.
The DL2000 uses FLASH upgradeable firmware from the configuration Software.
Green communication LED’s for each communication channel indicates activity and status. Red ERR Led indicates communication problems
