CC-Link System Master, Local Module User's Manual QJ61BT11

1 OVERVIEWMELSEC-Q1 OVERVIEWThis manual describes the specifications, parts names and settings of the QJ61BT11Control & Communication Link System Master/Local Module (hereinafter referred to asthe QJ61BT11) which is used with the MELSEC-Q series PLC CPUs.11.1 OverviewCC-Link is the abbreviation of the Control & Communication Link in this manual.Throughout this manual, it will be referred to as CC-Link.The CC-Link system connects distributed modules such as an I/O module, an intelligentfunction module, and a special function module using dedicated cables so that thesemodules can be controlled by the PLC CPU.(1) By distributing each module to an equipment device such as a conveyor line and amachine device, the wiring efficiency of the entire system can be accomplished.(2) On/off information of input/output and numeric data that are handled by modulescan easily be sent and received at high-speed.(3) By connecting multiple PLC CPUs, a simple distributed system can be configured.(4) By connecting various devices made by Mitsubishi's partner manufacturers, thesystem can provide flexible solutions to meet a wide range of user needs.Master stationPLC CPURemote I/O stationDevice manufactured by one of ourpartner manufacturersRemote device stationRemote I/O stationLocal stationIntelligent device stationPLC CPUMaster station ................
