Precautions
• Do not use extension cable longer than 13.2m (43.28 feet).
• When using the extension cable, keep it away from the main circuit (high voltage,
large current).
• Set the extension stage numbers in ascending order to avoid duplicated setting.
• The QA1S6 B/Q6 RB cannot be used as an extension base unit.
• When both Q5 B and Q6 B extension base units exists, there is no restriction
on the connection order for them. Refer to the QCPU User's Manual (Hardware
Design, Maintenance and Inspection) and check if they can be used.
• Connect the extension cable from OUT of the extension cable connector of the
base unit to IN of the next extension base unit.
• When modules are mounted on 26 or more slots, an intelligent function module
assignment error (error code: 2124, SP. UNIT LAY ERR.) occurs. (Including the
CPU module)
• "No. of CPU" indicates the number of CPU modules set in the "No. of CPUs" on
the <<Multiple CPU setting>> tab of the C Controller setting utility.
• Refer to the manuals of the corresponding CPU modules for details of the
programmable controller CPU and Motion CPU.
• When a multiple CPU system is configured using the C Controller module, the
redundant power base unit is not applicable.
