I/O NUMBER ASSIGNMENT
4.2 Relationship between No. of Extension Stages and No. of Slots
CPU modules can be used in the following system configuration.
• Configuration of one main base unit and extension base units
• Configuration of one slim type main base unit
(1) Number of stages and number of slots
Table4.2 indicates the number of base units (stages) and the number of slots
available for each CPU module.
: Available, : Not Available
* 1 : Extension base units cannot be connected to the slim type main base unit.
* 2 : The number of available slots (modules) includes empty slots.
(If Slot 2 is set to "Empty, 0 point" as shown in Figure 4.2, it occupies one slot.)
* 3 : The Redundant CPU whose serial number (first five digits) is "09012" or later is targeted.
When using the Redundant CPU whose serial number (first five digits) is "09011" or earlier, the
extension base unit cannot be connected to the main base unit.( Appendix 4.4)
Therefore, the number of available slots will be 11.
