Setting Node Addresses

the IN and OUT Areas from the default values.
To split the IN Area used by the E5AR/ER-DRT into two
areas, select E5AR/ER-DRT in the master's Edit Device
Parameters Window and set the connection in the detailed
settings.
When the IN Area is split into two areas, for example, oper-
ating parameters, such as set points and process values,
can be allocated in IN Area 1, and status values can be allo-
cated in IN Area 2. For example, IN Area 1 can be allocated
in the DM Area and IN Area 2 can be allocated in the CIO
Area.
Enable the master's scan list and change the PLC to RUN
Mode.
Remote I/O communications will start, and the contents of
the IN and OUT Areas in the master and E5AR/ER-DRT
Digital Controller will be synchronized.
Send explicit messages from the master.
Explicit messages can be used to perform control and mon-
itoring that cannot be achieved using the IN and OUT Areas
alone, by sending explicit messages to the E5AR/ER-DRT
Digital Controller.
Observe the following precautions when editing device parameters using the
Configurator.
• It is recommended that device default values are uploaded before the
parameters are edited because the EDS parameter defaults and the
device defaults are different.
• If "Unit No." (communications unit number) is displayed in the Communi-
cations Setting parameter group, set the "Unit No." to the node address.
• If "Input 2 Type" is displayed in the Input Initial Setting parameter group
for the E5AR-@@@B-DRT, E5ER-@@@B-DRT, E5AR-@@@F-DRT, or
E5ER-@@@F-DRT, set the "Input 2 Type" to 15. The default value may
not be downloaded.
• Related settings are not initialized when data is downloaded from the
Configurator. Refer to the Appendix in the E5AR/E5ER Digital Controller
User's Manual (Cat. No. H124) for information on how to correctly set
related data.
• The automatic selection range upper limit (DV) can be set from the front
panel or it can be set using the automatic selection range upper limit (PV)
parameter (PID*AUT(PV)). When using the automatic selection range
upper limit (PV) parameter, set the value obtained from the following
equation:
Automatic selection range upper limit (PV) = Automatic selection range
upper limit (DV) + Sensor setting range lower limit
DeviceNet node addresses are set in the communications setting level. Set
the node addresses on the front panel of the E5AR/ER-DRT.
• The node address will be 0 if an address between 64 and 99 is set.
