DeviceNet Remote I/O Communications Section 3-2
Note The above method can be used only if the Master Unit is a CS/CJ-series
DeviceNet Unit. When using a CVM1/CV-series DeviceNet Master Unit, a
C200HX/HG/HE/HS DeviceNet Master Unit, or another company’s Master
Unit, select the I/O data from the pull-down menu for the default connection
path in the Slave’s Edit Device Parameters Window.
3-2-2 I/O Allocations for Smart Slaves
General-purpose
Slaves and
Environment-resistive
Slaves
DRT2-slave data can be allocated for remote I/O communications with the
Master Unit using any of the following methods.
1,2,3... 1. Allocating only real I/O data (default)
2. Allocating real I/O data and Generic Status Flags together
3. Allocating real I/O data and Generic Status Flags independently
Method 2 can be performed by selecting the I/O data and flags from the
pull-down menu for the Slave’s default connection path using the Configu-
rator.
Method 3 can be performed by allocating real I/O data and Generic Status
Flags independently in the Master’s connection path using the Configura-
tor. (This method can be used only with CS/CJ-series Master Units.)
Type Selecting I/O data and allocating to user-defined addresses
Description Select up to two types of I/O data, and allocate to user-defined addresses in the Master Unit.
Method 1. Select up to two types of I/O data using the Configurator.
2. Allocate the selected I/O data to user-defined addresses in the Master Unit.
Configuration
