versions of the blocks. For example, for the EDS file for
1790D-T8BV8B blocks, use the EDS file labelled 1790D-8BV8B.
Install the Base Block
To install the base block:
•
set the node address on the base block.
•
mount the base block.
•
mount the optional expansion blocks.
•
wire the terminal block.
•
connect the DeviceNet cable.
Set the Node Address
When setting the node address on the base block, note that each base
block comes with its internal program set for node address 63. To
reset the node address, adjust the switches on the front of the base
block. The two switches are most significant digit (MSD) and least
significant digit (LSD). You can set switches to 00...63.
Node Address Example
The base block reads the rotary switches only when power is
applied. Switch settings 64…99 cause the base block to use the last
valid node address stored internally.
You can also set the node address through RSNetWorx for DeviceNet
software or a similar configuration tool.
When you use software configuration for the node address, set the
switches to 64…99.
In this
example, the
node address
setting is 11.
