6 DeviceNet Digital Base Terminal Block CompactBlock LDX I/O

Example: Node Address is set at 11

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 on the Base Block

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 at power up only. Switch settings between 64 and 99 cause the 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.

Cable Break Procedures

A cable break in any location between either of the following produces data of 0 in the data table for all inputs down stream of the cable break:

• Base and digital input expansion module

• Digital input expansion module and another digital input expansion module

All digital-expansion inputs produce data of 0 if the expansion cable is removed. No status is in the default produced assembly. Attribute 101 in the identity object reports module faults.

If no faults are present, an explicit message GET command returns 0.

If the ribbon cable is disconnected, it returns 0x04, which is for module location change. The module status indicator also flashes indicating a fault if an expansion is disconnected. Select an alternate produced assembly that contains the expansion status byte, using the EDS Properties configuration dialog.
