Before You Begin
Read this section about CompactBlock LDX I/O block requirements.
Current functions of CompactBlock LDX I/O blocks require the
current, modular electronic data sheet (EDS) file for RSNetWorx for
DeviceNet software, version 3.0 or later. These files are available
online at www.ab.com.
EDS files for blocks with matching catalog numbers for both D-Shell
and terminal block versions are the same. On the Web site and in
RSNetWorx for DeviceNet software, find the EDS file for both 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 between 00 and 63.
The base block reads the rotary switches only when power is
applied. Switch settings between 64 and 99 cause the base
block to use the last valid node address stored internally
.
