CHAPTER4 I/O NUMBER ASSIGNMENT
This chapter explains the I/O number assignment required for the CPU module to
communicate data with I/O modules and/or intelligent function modules.
4.1 Relationship between Number of Slots and Main Base Unit
(1) Available main base units
Table4.1 indicates the main base units and/or slim type main base units available for
each CPU module.
* 1 : The Q00JCPU is a CPU module integrated with a power supply module and a main base unit.
It requires no power supply module and main base unit.
* 2 : The high speed access function between Multiple CPUs cannot be used.
(2) Number of available slots
The number of available slots (modules) includes empty slots.
(If Slot 2 is set to "Empty, 0 point" as shown in Figure 4.1, it occupies one slot.)
The number of available slots (modules) varies depending on each main base unit.
QCPU User's Manual (Hardware Design, Maintenance and Inspection).
For the concepts of base unit assignment and I/O number assignment, refer to
Section 4.4 and Section 4.6.
