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
2-1-3 Setting Node Addresses
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.
10 Operate from the Configurator. Set from the Configurator when changing data allocated in
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.
SECTION 4
Remote I/O Com-
munications
11 Start remote I/O communica-
tions. 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.
---
12 Use explicit message commu-
nications. 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.
