3.3 System Using Universal Model QCPU as CPU No.1
3.3.1 Available CPU modules, base units, power supply modules, and extension cables
*1 For the CPU modules that can be combined and their mounting positions, refer to Page 60, Section 3.3.2.
*2 When the Q00UCPU, Q01UCPU, or Q02UCPU is used as CPU No.1, two more CPU modules (CPU No.2 and No.3) can
be mounted. The following CPU modules can be mounted as CPU No.2 and No.3.
*3 These modules and units can be used when a Universal model QCPU with a serial number (first five digits) of "13102" or
later is set as the control CPU of AnS/A series modules. These modules and units cannot be used in a multiple CPU
system containing a Process CPU ( Page 188, Appendix 3)
*4 When the QA1S6B is used as an extension base unit, the QA6ADP+A5B/A6B cannot be connected.
*5 Since the QA1S51B does not have an extension cable connector (OUT), it cannot be used with the QA6B or
QA6ADP+A5B/A6B.
*6 When the QA1S6ADP+A1S5B/A1S6B is used, the maximum number of extension base units is 1, and the maximum
number of I/O modules that can be mounted is 20 minus the number of CPU modules. When the QA1S6ADP-
S1+A1S5B/A1S6B is used, the maximum number of extension base units is 3, and the maximum number of I/O
modules that can be mounted is 36 minus the number of CPU modules.
(b) Precautions
• If I/O modules are mounted exceeding the maximum number, "SP.UNIT LAY ERR" (error code: 2124)
occurs.
• "Number of CPU modules" indicates the number set in "No. of PLC" of PLC parameter ("Multiple CPU
Setting").
• When a C Controller module which occupies three slots is used, the maximum number of mountable I/O
modules will be two smaller than the number defined in the table on Page 56, Section 3.3.1 (2) (a).
• A PC CPU module occupies two slots. When this module is used, the maximum number of mountable I/O
modules will be one smaller than the number defined in the table on Page 56, Section 3.3.1 (2) (a).
