When the MicroSmart is connected to a computer, operating status and I/O status can be monitored on the computer, data
in the CPU module can be monitored or updated, and user programs can be downloaded and uploaded. When an optional
RS485 communication adapter is installed on the port 2 connector of the all-in-one 16- or 24-I/O type CPU modules or
when an optional RS485 communication module is mounted with any slim type CPU modules, a maximum of 32 CPU
modules can be connected to one computer in the 1:N computer link system.
For details about the computer link communication, see pages 4-1 and 26-1.
