Cat. No. 1784–KT2/C
Installation Data
The 1784–KT2/C Communication Interface Module allows you to use an
IBM PS/2 compatible MicroChannel computer to communicate with:
Allen-Bradley PLC–2 and PLC–3 family programmable controllers
all Data Highway Plus family programmable controllers
The 1784–KT2/C conducts the data communication, management, and
local Data Highway Plus diagnostics. The interface to the personal
computer is through board-resident shared memory that passes
preformatted Data Highway Plus packets. Upon powering up the computer
and downloading module code, diagnostics are run automatically to verify
the 1784–KT2/C's operation. Allen-Bradley 6001–F1E2 software manages
the transmission and reception of data through board-resident shared
memory.
The 1784–KT2/C Communication Interface Module is an IBM PS/2
MicroChannel card that you can insert into any 8– or 16–bit IBM PS/2
expansion slot. In addition, the 1784–KT2/C:
makes your PS/2 computer an active node on a Data Highway Plus
network
provides single cable connection to a PLC–2, PLC–3, or PLC–5 family
programmable controller
operates with 6200 programming software
is address selectable; you can use it with other option boards installed in
your PS/2 computer
when combined with Allen-Bradley 6001–F1E2 software, allows you to
create your own custom interface to a Data Highway Plus network
