The DL-PC (DL) is an ISA bus pc card that
enables Computers, PCs and OEM equipment to connect to Allen-Bradley
networks at high-speed. The DL can be configured as either a station on Data
Highway Plus or as one or more adapters (virtual racks) on Remote I/O.

DL's interface to
ISA bus using the same COM port emulator as an internal modem card. The
built-in COM port front-end buffers the byte data in RAM memory, converts it
to serial and then transmits it directly to DH+ or RIO at full network
speeds.
The DL's
built-in CPU, RAM, and operating firmware in socketted EPROM frees-up
valuable computer memory and system resources for use by the application.
This unique approach enables ISA bus computers to connect to A-B networks at
high speeds using standad communications software. The actual system
throughput will depend on CPU, clock speed, application software, A-B
network speed and traffic etc.
 The
DL enables existing A-B DF1 serial drivers, ie. drivers for PLC Channel 0,
1770-KF2 or 1785-KE, to be used with Operating Systems including DOS, Unix &
Windows, in applications such as Operator Interfaces, PLC Programming, SCADA
and Data Acquisition.
In adapter
mode the DL can be configured for 1 to 8 (virtual) racks. A computer can
read all the I/O image data on RIO, write a maximum 1024 bits and read/write
64 data blocks of up to 64 words each. |
