3-2 Installation
3-2-1 System Configuration Precautions
CJ1W-MCH71 • When using the IOWR/IORD instructions for the MC Unit, be sure that a
version 2.0 or later CJ1-H/CJ1M CPU Unit is being used.
• I/O bit numbers of the CPU Bus Unit are allocated based on the setting of
the Unit Number Setting Switch on the front panel of the Unit, not on the
position in which the Unit has been connected.
• MC Units can be connected in either the CPU Rack or in Expansion
Racks. A maximum of 3 MC Units can be connected per Rack. The total
number of MC Units for the CPU Rack and all Expansion Racks is thus 12
MC Units maximum.
• When mounting a relay output unit on the very right of the MC Unit, make
sure to use the surge absorber for the relay output line.
When MECHATROLINK-II devices are connected up to 16 nodes (within
30 m) or 15 nodes (within 50 m), no repeater unit is required. A repeater unit
is required to connect MECHATROLINK-II devices more than the cases
above.
CS1W-MCH71 • When using the IOWR/IORD instructions for the MC Unit, be sure that the
CS1 @ -CPU @@ H CPU Unit being used was manufactured on April 18,
2003 (Lot No. 030418) or later.
• The I/O words allocated to a CPU Bus Unit are based on the setting of the
unit number setting switch on the front panel of the Unit, not on the posi-
tion in which the Unit has been mounted.
• The Units can be mounted to the CS1W-BC
