A simple and cost effective way to access Allen Bradley's Data
Highway Plus can be realized using Kepware's Allen Bradley
DF1 Driver and DATA LINK Technologies, Inc. DL-PC communications
KEPServerEX's Allen Bradley DF1 driver uses the Allen Bradley DF1 protocol
to provide direct connection to Allen Bradley equipment which supports DF1 or
Channel 0 communications. Accessing multiple devices on a Data Highway Plus
network would normally require the use of a converter like the Allen Bradley
KF2 module. The KF2 module is effective but can be still be costly and doesn't
provide high speed access the Data Highway Network.
DATA LINK Technologies provides a solution that is both
cost effective and offers high speed access. The DATALINK
DL-PC communications card for the ISA bus provides a high
speed link between KEPServerEX's DF1 driver and the Data Highway
Plus network. The DL-PC
card acts as a DF1 to Data Highway Plus converter. Once installed
in your PC the DL-PC acts and appears like a standard PC
communications port. Once the DL-PC is assigned to
a communications port you can simply select that port when
configuring the DF1 driver within KEPServerEX. The DL-PC card
supports a baud rate of up to 115K baud. The DL-PC card
must be configured to use CRC as the message check method.
After the driver is configured, access to multiple devices
on the Data Highway Plus network is easy and fast.
