Precautions
• Do not use an extension cable longer than 13.2m (43.31 ft).
• When using an extension cable, keep it away from the main circuit (high voltage and large current) line.
• Set the number of extension stages so as not to be duplicated.
• When the Q5 B, Q6 B, QA1S6 B, QA6 B, and QA6ADP+A5B/A6 B
extension base unit, mount the Q5 B/Q6 B, QA1S6 B, QA6 B, and QA6ADP+A5 B/A6 B in order
from the nearest position of the main base unit.
Although there is no restriction on the connection order of the Q5 B and the Q6 RB, check the availability
of them by referring to QCPU User's Manual (Hardware Design, Maintenance and Inspection).
• The extension base units QA1S6 B, QA6 B, and QA6ADP+A5 B/A6 B can be extended when the High
Performance model QCPU is set as the control CPU of the AnS/A series.
When the Process CPU or the Universal model QCPU is used, extension is not allowed.
• The Q6 RB cannot be connected as an extension base unit.
• Connect the OUT connector of an extension base unit and the IN connector of the adjacent extension base
unit by an extension cable.
• When 66 modules or more are mounted, an error "SP. UNIT LAY ERR." (error code: 2124) occurs. (The
number of mountable modules includes one CPU module.)
• "No. of CPUs" is the number of CPUs set by [No. of PLC] of GX Developer.
• When mounting the Universal model QCPU and the PC CPU module at the same time, use the PPC-
CPU852 (MS)-512 as the PC CPU module.
• The PC CPU module and C Controller module cannot be mounted together: therefore; mount either of them.
• The PC CPU module occupies two slots. Therefore, when the PC CPU module is used, the maximum
number of I/O modules is decreased by 1 from the value indicated in Table2.4.
• For details of the Motion CPU, and PC CPU module, refer to the manual of each CPU module.
*1: When using the QA1S6 B, the QA6ADP+A5 B/A6 B cannot be connected.
