2.3 System Configuration Specifications
Description
Check the number of extension devices to be connected
to the CPU module and their connection methods. The
number of connected modules and the connection
methods differ depending on the CPU module used.
For some modules, the number and combinations of
modules that can be used in one system are restricted.
Check the number of connectable modules, the
combinations of modules, and the order of connection.
Check that the number of I/O points in the entire system
does not exceed the number of I/O points that can be
controlled by the CPU module.
Check that the internal current consumption of the entire
system does not exceed the rated output current in the
power supply specifications.
