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.
