1-1 Features
• The CQM1-LK501 I/O Link Unit can communicate with other PCs via I/O
points connected to the SYSMAC BUS Wired Remote I/O System.
• The CPU treats the CQM1-LK501 I/O Link Unit as an I/O Unit with 32
input and 32 output points so that the user can communicate with remote
PCs with ease.
The SYSMAC BUS Wired Remote I/O System connects remote I/O devices
and PCs. The SYSMAC BUS Wired Remote I/O System saves wiring effort
because each PC is connected over a single wire. The CQM1-LK501 I/O Link
Unit makes PC communications possible via I/O points in the SYSMAC BUS
Wired Remote I/O System. Refer to SYSMAC C-series Rack PCs Wired
Remote System Manual (W120) for details on the SYSMAC BUS system.
