I/O Expansion for Slim Type CPU Modules
All slim type CPU modules can connect a maximum of seven expansion I/O modules including analog I/O modules.
The expandable I/O points and the maximum total I/O points vary with the type of CPU module as listed below.
Allocation Numbers (Slim Type CPU Modules)
Example:
The system setup shown above will have I/O operand numbers allocated for each module as follows:
The I/O numbers of the CPU module start with I0 and Q0. The I/O numbers of the expansion I/O modules start with I30
and Q30. When an I/O module is mounted next to a 4/4-point mixed I/O module, note that the allocation numbers skip
four points as shown above.
Input and output modules may be grouped together for easy identification of I/O numbers. When the I/O modules are relo-
cated, the I/O numbers are renumbered automatically.
