Details of each item of detailed remote station information
1) Number of I/O points (b4 to b0)
The number of I/O points used in each station number assigned to each buffer memory is
stored here.
The maximum number of points is 4 or 16 in accordance with the number of points per
station set by the DIP switch for operation setting.
When a remote I/O unit with 16 I/O points is used in the 4-point mode, the number of points
per buffer memory is 4, and the I/O points of the remote I/O unit are assigned to four buffer
memories.
In the case of a composite I/O unit, the larger one between the number of input points and
the number of output points is stored here.
In the case of remote device station, 16 points are stored here.
