DataLink GW1500-DHP1: DF1 to DH+  Multi-Protocol Converter

$1,395 USD list


DF1 Interface for Computers, OEM Equipment, Modems, and CH0 PLCs to AB’s DH+  (DataHighway Plus).  Alternative / Replacement for 1770-KF2, 1784-P(KTX), 1784-PCMK or 1784-U2DHP.



GW1500 Gateway

The GW1500 is our next generation, multi-protocol gateway that can easily be converted to several protocols with a firmware change (ie. DF1, ASCII, Modbus, ModTCP, AB Ethernet or Ethernet/IP to multiple DH+/DH-485) all for $1,395 USD list.  

You may wish to program your PLC with RSLINX (1770-KF2 driver) serial DF1 to DH+ on the plant floor or change firmware to RSLINX (AB Ethernet driver) remotely over Ethernet with our GW1500-ABEIP firmware.

GW1500-DHP1: DF1 to DH+ Gateway

The DataLink GW1500-DHP1 is a low cost, compact alternative to Allen-Bradley’s 1770-KF2. It also provides the same functionality as the 1784-P(KTX), 1784-PCMK & 1784-U2DHP.

The DataLink converts A-B DF1 serial protocol to A-B DH+ network protocol providing a serial interface to DH+ for computers, modems and OEM equipment.

Applications include: PLC programming and graphical user interfaces (GUIs and MMIs) such as RSLINX, RSLOGIX, Wonderware, Kepare, Intellution, Citect, etc. The GW1500′s size, portability, and the choice between a freestanding and DIN rail model make it especially convenient for use in the office, the plant floor, or when travelling.

In the GW1500-ABEIP Ethernet mode (flash firmware update), the GW1500 has the ability to communicate with 5 Ethernet connections simultaneously to DH+ (ie. up to 5 RSLINX workstations, SLC 5/05, Compactlogix etc. connections) .

Protocol Flexibility: The GW1500 is a multi-protocol gateway that can be easily converted between DF1, ASCII, Modbus, ModTCP, AB Ethernet or Ethernet/IP to DH+ or DH-485 with a simple firmware change.

Compact and Lightweight: Palm-size, portable freestanding Din Rail/desktop controller with USB, AC/DC power option. Size and portability makes it convenient for use in the office, the plant floor, or when travelling.

Easy Configuration: All setup &  configuration is done via Web screen or Telnet.

Cost efficient Alternatives:  All protocols are available in one GW1500 Gateway for $1,395 USD list.

In Ethernet mode, the GW1500-ABEIP provides similiar functionality to the  Controllogix (1756-DHRIO/1756-ENBT) Gateway.  In DF1 mode,  the GW1500-DHP1 provides same external functionality as the 1770-KF2,1784-P(KTX), 1784-PCMK & 1784-U2DHP.
