5-3 Switching Remote I/O Operation
To use remote I/O operations other than the standard remote I/O operation it is necessary to switch the
remote I/O operation. There are two ways to switch:
• Use the Configurator to set the remote I/O instance IDs for parameter objects.
• Set the remote I/O instance IDs for connection objects.
When an OMRON Master Unit is used, however, only the method utilizing the Configurator can be used
to switch remote I/O operations.
Note OMRON Master Units assume that communications will use remote I/O, so remote I/O commu-
nications are executed when the power is turned ON. Remote I/O operations cannot be switched
during operation under DeviceNet protocol. If remote I/O operations need to be switched, it must
be done by using the Configurator with the Master Unit’s power supply turned OFF.
H Switching via Parameter Objects (Using the Configurator)
To switch remote I/O operations using parameter objects, the appropriate instance IDs must be set for
the following parameter objects.
• Switching remote I/O inputs (3G3FV to SYSMAC PC):
Class 100 dec (64 hex), Instance 01 dec (01 hex), Attribute 202 dec (CA hex)
• Switching remote I/O outputs (SYSMAC PC to 3G3FV)
Class 100 dec (64 hex), Instance 01 dec (01 hex), Attribute 203 dec (CB hex)
The instances to be set are shown in the following table.
Remote I/O type
Instance ID
Inputs (3G3FV to PC) Outputs (PC to 3G3FV)
Basic remote I/O 70 Dec (46 hex) 20 Dec (14 hex)
Standard remote I/O 71 Dec (47 hex) 21 Dec (15 hex)
Special remote I/O 150 Dec (96 hex) 100 Dec (64 hex)
The procedure for switching remote I/O operations by means of object parameters is as follows:
1. Connect the 3G3FV Inverter and a Configurator to the CompoBus/D communications network. At
least a 3G3FV CompoBus/D Communications Card and a Configurator must be connected.
2. Set up the explicit message connection with no remote communications.
S Turn ON the power to the Configurator and the 3G3FV CompoBus/D Communications Card and
press the Configurator’s online button. Do not turn ON the power to the Master Unit at this time.
This will put the system into online status.
S Click the Device List button at the upper left corner of the Configurator screen. With this, the explic-
it message connection will be set up.
3. Connect the remote I/O to be used for the parameter objects.
S Select Tool (T) and then Device Parameter Setting (P) from the Configurator tool bar to display the
parameter setting tool.
S Set the node address, and then set the remote I/O instance IDs for the parameter objects de-
scribed above (attributes CA and CB hex of class 64 hex, instance 01 hex).
4. Cut off the Configurator and explicit message connection by turning OFF the power to the Inverter.
