1-2 Introduction to the 1784-KTx Communication Interface Cards
1784-6.5.22 - November 1999
How the 1784-KT x Card Operates
The 1784-KTX and -KTXD cards:
• communicate with nodes on Data Highway networks, including PLC-2 ® ,
PLC-3 ® , and on Data Highway Plus networks, including PLC-5 ® ,
and SLC 5/04 processors, and SLC 5/01 ™ , SLC5/02, and SLC 5/03
processors (only via 1784KA5)
• communicate with SLC ™ processors on DH-485 networks
• act as a remote I/O scanner
The 1784-KTS card acts only as a remote I/O scanner.
The 1784-KTx performs data transmission, management, and local network
diagnostics. The interface to the host processor is through a board-resident
dual-port memory.
Allen-Bradley interface software (including RSLogix via RSLinx, AI, 6200, and
INTERCHANGE) manages data transmission and reception through dual-port
memory.
Remember to set the base memory address on the KTx card so that it does not
interfere with selected addresses of other expansion cards in your computer. On
dual-channel cards, set two addresses.
Important: Although the 1784-KTXD has two channels, you cannot use the
card to directly bridge between two networks.
