3.2.1 Configuration example

(1) PLC side
Fit "Type AJ61BT11", "Type A1SJ61BT", "Type AJ61QBT11" or "Type A1SJ61QBT" "Control &
Communication Link system master/local module" to the main or extension base unit which is loaded
with the PLC CPU used as the master station.
(2) Wiring
Connect the PLC CC-Link unit master station and MR-J2-T01 CC-Link option unit by a twisted pair
cable (3-wire type).
(3) For the CPU having the automatic refresh function (Example: QnA series CPU)
Transfer of data to/from the corresponding devices is performed from a sequence ladder and the
devices are automatically refreshed by the refresh buffer of the master station at the END instruction
to make communications with the remote devices.
(4) For the CPU having no automatic refresh function (Example: AnA series CPU)
Transfer of data to/from the refresh buffer of the master station is performed directly from a sequence
ladder to make communications with the remote devices.
