Precautions
• Do not use extension cable longer than 13.2 m (43.28 feet).
• When using an extension cable, keep it away from the main circuit (high voltage
and large current).
• When setting the number of extension stages, set the number in ascending order
to avoid duplicated setting.
• If Q5 B / Q6 B and QA1S6 B extension base units are used in the same
system, be sure to connect Q5 B / Q6 B at first and then QA1S6 B.
Make the setting of the stage number of extension base units, starting from
Q5 B / Q6 B in ascending order. Refer to the QCPU User's Manual (Hardware
Design, Maintenance and Inspection) and check if they can be used.
• The QA1S6 B extension base unit can be used only when all of the AnS series
modules are set to be controlled by the same High Performance model QCPU.
Note that it cannot be used if a Process CPU is used.
• The Q6 RB cannot be connected as an extension base unit.
• Connect an extension cable between the OUT connector of an extension base
unit and the IN connector of another extension base unit.
• When 66 or more modules are mounted, an intelligent function module
assignment error (error code: 2124, SP. UNIT LAY ERR.) occurs. (Including the
CPU module)
• "Number of CPUs configured" indicates the number of CPU modules set in
"Number of CPUs" on the <<Multiple CPU settings>> 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.
• Installation of a Universal model QCPU (except for Q02UCPU) and a Motion
CPU (except for Q172DCPU and Q173DCPU) is not allowed for the same
system.
Select either one of them.
• When a multiple CPU system is configured using a C Controller module,
redundant power supply base units are not applicable.
