DeviceNet Digital Base D-shell Block CompactBlock LDX I/O 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.
DeviceNet Digital Base D-shell Block CompactBlock LDX I/O 7 Node Address Setting In this example, the node address setting is 11. NODE ADDRESS MOD NET STATUS MSD 44202 LSD 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 between 64 and 99. Mount the Base Block Mount the base block to a panel or DIN rail.
DeviceNet Digital Base D-shell Block CompactBlock LDX I/O Mount on a Panel For panel mounting, use these steps. Block Dimensions 95 mm (3.74 in.) 41 mm (1.6 in.) Expansion Cover 44153 1. Place the block against the panel where you want it mounted. 2. Gently pull and position the expansion cover to the left. 3. Place a center punch, nail, or similar device through the mounting holes in the block and make two marks on the panel at the lower-left and upper-right corners of the module. 4.
DeviceNet Digital Base D-shell Block CompactBlock LDX I/O 9 Mount on DIN Rail For DIN-rail mounting, use these steps. 1. Hook the top slot of the base block over the DIN rail. Locking Lever 44154 2. Pull down on the locking lever while pressing the base block against the rail. 3. Push up on the locking lever to secure the base block to the rail when the base block is flush against the rail.

DeviceNet Digital Base D-shell Block CompactBlock LDX I/O WARNING If you connect or disconnect the DeviceNet cable with power applied to this module or any device on the network, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding. 1.
DeviceNet Digital Base D-shell Block CompactBlock LDX I/O 15 Interpret the LED Indicators Read this section for information about how to interpret block LED indicators and related procedures. For a module status indicator that is flashing red, refer to the cable break procedure section. The base block has the following indicators: • Block status • Network status • I/O status Interpret the LED Indicators LED Indicator Probable Cause Recommended Action Solid Red Unrecoverable fault in base unit.
DeviceNet Digital Base D-shell Block CompactBlock LDX I/O Interpret the LED Indicators LED Indicator Probable Cause Recommended Action Solid Green The module is operating in a normal condition, and the module is online with connections in the established state. As a group 2 module, the module is allocated to a master. None. Flashing Green The module is online with no connections in the established state. Establish connections to other nodes. As a group 2 module, allocate the module to a master.
DeviceNet Digital Base D-shell Block CompactBlock LDX I/O 17 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 LED indicator also flashes indicating a fault if an expansion is disconnected.
