DeviceNet Digital Base Terminal Block CompactBlock LDX I/O 7 Before You Begin Read this section about important CompactBlock 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 are available online at www.ab.com/networks/eds/. EDS files for blocks with matching catalog numbers for both D-Shell and terminal block versions are the same.
DeviceNet Digital Base Terminal Block CompactBlock LDX I/O 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. In this example, the node address setting is 11. 44152 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.
DeviceNet Digital Base Terminal Block CompactBlock LDX I/O 9 Mount on a Panel For panel mounting, use these steps. 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 Terminal Block CompactBlock LDX I/O 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 Terminal Block CompactBlock LDX I/O 11 Mount your block on a panel or DIN rail. Horizontal Mounting Vertical Mounting The longer expansion cable (1790-15CMCBL) provides for up to 7 cm (2.76 in.) of space in between blocks. 44155 Wire the Terminal Block WARNING If you connect or disconnect wiring while the field-side power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations.

DeviceNet Digital Base Terminal Block CompactBlock LDX I/O 15 Connect the DeviceNet Cable Follow these procedures to connect the DeviceNet cable to the base block. We do not supply the DeviceNet connector with the base block. You must purchase the connector separately. These are the types of connectors you order directly from Rockwell Automation.
DeviceNet Digital Base Terminal Block CompactBlock LDX I/O 2. Attach the connector to the base block once you have properly wired the drop line to the connector. 3. Use the locking screws on the connector to fasten it to the base block, if applicable. Interpret the LED Indicators Read this section for information about how to interpret base block LED indicators. The base block has the following indicators.
DeviceNet Digital Base Terminal Block CompactBlock LDX I/O 17 Indication 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. Off No power.
DeviceNet Digital Base Terminal Block CompactBlock LDX I/O All digital-expansion inputs produce data of 1 if the expansion cable is removed. No status is in the 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 also flashes indicating a fault if an expansion is disconnected.
