9.11.6 Number of occupied stations and Link scan time

If the number of stations is equivalent, the link scan time is longer in 16-point mode than in 4-point mode.

9.11.7 Cautions on I/O number assignment

1. I/O operation
The following inputs/outputs do not operate in CONFIG mode.
1) Inputs/outputs in the remote I/O stations connected to the built-in master do not operate.
2) I/O extension units/blocks connected to the PLC do not operate.
2. When an I/O extension block or the FX
future
The I/O numbers in the remote I/O station connected to the built-in master are shifted to positions after the
I/O numbers in the added I/O extension block or FX
I/O numbers in programs.
3. When a remote device station is used
Note that the I/O numbers are shifted forward if the following setting is performed by mistake in specifying a
reserved station
1) The reserved station is set to an I/O station instead of a remote device station (analog unit) by mistake.
2) An analog unit is connected, and X/Y numbers are used.
By operations 1) and 2), an analog unit is activated.
3) "CONFIG" is executed again.
4) The I/O number assignment shifts backward.
The analog unit is accessed in the BFM.
