Precautions
• Do not use extension cable longer than 13.2 m (43.28 feet).
• When using the extension cable, keep it away from the main circuit (high voltage,
large current).
• When setting the number of extension stages, prevent number duplication.
• If the Q5 B and Q6 B extension base units are used in the same system, there
are no restrictions 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.
• The QA1S6 B and Q6 RB cannot be used as an extension base unit.
• Connect the extension cable from OUT of the extension cable connector of the
base unit to IN of the next 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 CPU
modules)
• "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
programmable controller CPUs.
• Motion CPUs cannot be mounted.
