Structure of Authentication Class B/A Devices and
Ethernet Devices
This section describes the system configuration when "Connection Device Information" under "Basic Settings" of the
engineering tool is set to "Mixture of Authentication Class B/A or Authentication Class A Only".
When "Connection Device Information" under "Basic Settings" of the master station is set to "Mixture of Authentication Class
B/A or Authentication Class A Only", up to 121 devices (1 master station and 120 slave stations) can be connected.
