Expansion Remote I/O
Section 4-4
OFF to ON: 100% autotuning execution command. (Executed only once each
time the bit is turned ON.)
OFF:
Autotuning cancel command. (Executed while the bit is OFF.)
Note
Always allocate AT Execute/Cancel after RUN/STOP or Auto/Manual. If it is
allocated before, AT execution and RUN or Auto will not be performed at the
same time.
Auto/Manual
ON: Manual mode command. (Executed while the bit is ON.)
OFF: Auto mode command. (Executed while the bit is OFF.)
Combining TC2 and
TC4 Units
Operation will be as follows if simple I/O allocation is used and both TC2 and
TC4 Units are connected to a DeviceNet Communications Unit or if the Con-
figurator is used to allocate I/O for both TC2 and TC4 Units.
Simple I/O Allocation
• If a TC4 Unit is used and simple I/O allocation is performed for TC2 Units
(i.e., with DIP switch pin 2 turned OFF), channel 1 and channel 2 data will
be used for channel 1 and channel 2 of the TC4 Unit.
• If a TC2 Unit is used and simple I/O allocation is performed for TC4 Units
(i.e., with DIP switch pin 2 turned ON), channel 1 and channel 2 data will
be used for channel 1 and channel 2 of the TC2 Unit.
Allocating I/O from the
Configurator
If data is allocated for both TC2 and TC4 Units, the data will be allocated
according to unit number in each allocated area, regardless of whether the
Units are TC2 or TC4 Units. This may result in the same data in two different
places for the same unit numbers for the channels that are available.
Example: The data in the shaded areas of the following table will be used if a
TC2 Unit set as unit 0 and a TC4 Unit set as unit 1 are connected to
a DeviceNet Communications Unit.

What Is Expansion Remote I/O?
Expansion remote I/O is a function reading and writing parameters. Specific
parameters allocated in I/O memory of the master can be switched to a vari-
ety of parameters by using memory operations. This function enables manipu-
