Unit Status

This section explains the Unit status information, which is allocated in the Master when remote I/O
communications are used and can be used to easily monitor the Unit's status. Refer to 5-2 Switching
the Remote I/O Function for details on allocating unit status to the Master. Refer to 7-2 Smart Slave
Functions for details on making settings such as each functions threshold value.
Note When using the control I/O remote I/o function, there is a default setting available (a default
connection path setting), which attaches the unit status (16 bits) to the remote I/O.
