Start Point Of The I/O Numbers (00H) - Mitsubishi Electric MELSEC Q Series User Manual

16.1.4
Start point of the I/O numbers (00
The following describes a start point of the I/O numbers (00
(1) Automatic assignment
In case of automatic assignment, the start point of the I/O number (00
(a) For a single CPU system
Slot 0 of the main base unit is assigned as 00
(The immediate right of the C Controller module is Slot 2.)
(b) For a multiple CPU system
The right hand side slot of each CPU module set in parameters in the main base unit is assigned as 00
Use the following functions in Setting/monitoring tools for the C Controller module to set the number of CPUs.
•
Project view  "Parameter"  "CCPU Parameter"  <<Multiple CPU settings>>  "No. of CPU"
(2) To set the immediate right of the Q24DHCCPU-V/-VG/-LS and Q26DHCCPU-LS
as a start point
The Q24DHCCPU-V/-VG/-LS and Q26DHCCPU-LS takes up 3 slots. 2 of the 3 slots are treated as empty slots.
Therefore, the start point (00
Q24DHCCPU-V/-VG/-LS and Q26DHCCPU-LS.
To set the immediate right of the Q24DHCCPU-V/-VG/-LS and Q26DHCCPU-LS (slot to which the I/O modules
and intelligent function modules can be actually inserted) as the I/O number start point (00
following settings in parameters.
(a) Setting the number of occupied points for empty slot
Use Setting/monitoring tools for the C Controller module to set the number of occupied points for empty slots to
0.
•
Project view  "Parameter"  "CCPU Parameter"  <<System settings>>
 "Points Occupied by Empty Slot"
(b) To set I/O assignment
Set the type and number of points of 2 right-hand slots of the used slots to "Empty" and "0 Point", respectively.
• Setting example of Q24DHCCPU-V
In case of the multiple CPU system, set the type to "CPU (Empty)".
