4-1-2
Example System Configuration
This section explains the operating procedure for the following minimal sys-
tem configuration. Connect the communications cable between the DeviceNet
Master Unit and DeviceNet Communications Unit after connecting the desired
Slice I/O Units to the DeviceNet Communications Unit.

Preparation for Operation
4-2-1
Determining the Slice I/O Terminal’s I/O Specifications
A single GRT1-DRT DeviceNet Communications Unit can control up to 64
Slice I/O Units with up to 1,024 I/O bits (64 words). In this example the Slice I/
O Terminal has the following configuration.
• 16 inputs
• 16 outputs
4-2-2
Selecting the Slice I/O Units
The following devices were selected, as shown in the basic system configura-
tion in
4-1-2 Example System Configuration
.
Master Unit: CS1W-DRM21-V1
DeviceNet Communications Unit: GRT1-DRT1
Slice I/O Units: Four GRT1-ID4, four GRT1-OD4, and one GRT1-END
Note
OMRON has a wide variety of DeviceNet compatible Master Units and Slave
Units available. Select the best Units for your application.

Confirming Specifications
Number of I/O Points Less
Than 1,024 (64 Words)
Verify that the total number of I/O points is less than the maximum of 1,024
points (64 words). This example uses the following calculation:
4 Units × 4 inputs (16 points) + 4 Units × 4 outputs (16 points) = 32 points
Power Consumption Less
Than 80 W/Block
Verify that the power consumption is less than 80 W per block. This example
uses the following calculation:
1 GRT1-DRT Unit × 3 W = 3 W
4 GRT1-ID4 Units × 1 W = 4 W
4 GRT1-OD4 Units × 1 W = 4 W
Total =
11 W
