Installing CompactBlock LDX I/O
Follow these steps to install the block:
1. Set the node address on the base block.
2. Mount the base block.
3. Mount the optional expansion blocks.
4. Wire the D-Shell connectors.
5. Connect the DeviceNet cable.
These steps are explained in detail in the following
procedures.
Set the Node Address on the Base Block
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 block. The two switches are most significant
digit (MSD) and least significant digit (LSD). The switches can
be set between 00 and 63.
The base block reads the rotary switches at power up only.
Switch settings between 64 and 99 cause the block to use the
last valid node address stored internally
.
The node address may also be set through RSNetWorx for
DeviceNet or a similar configuration tool. When software
configuration is used for the node address, the switches must
be set between 64 and 99.
Example: Node
Address is set at 11
