Before You Begin Read this section about important CompactBlock I/O requirements. Current functions of CompactBlock LDX I/O blocks require the current, modular electronic data sheet (EDS) file for RSNetWorx for DeviceNet software, version 8.0 or later. These files are are available online at http://www.ab.com/networks/eds/. EDS files for blocks with matching catalog numbers for both D-shell and terminal block versions are the same. On the website and in RSNetWorx for DeviceNet software,ind 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. Publication 1790-IN012C-EN-P - January 2015 6 DeviceNet Digital Base Terminal Block CompactBlock LDX I/O 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 Example: Node Address is set at 11 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. Publication 1790-IN012C-EN-P - January 2015 DeviceNet Digital Base Terminal Block CompactBlock LDX I/O 7 Mount the Base Module Mount the base block to a panel or DIN rail. We recommend that you ground the panel or DIN rail before mounting the block. Dimensions 95 mm (3.74 in.) 44251 41 mm (1.6 in.)

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. Remove the block and drill two holes in the panel to accommodate each of the mounting screws. 5. Replace the block on the panel and place a screw through each of the two mounting holes. 6. Tighten the screws until the block is firmly in place. Mount on DIN Rail For DIN-rail mounting, use these steps. 1. Hook the top slot of the base block over the DIN rail. 44253 Locking Lever 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. Publication 1790-IN012C-EN-P - January 2015 DeviceNet Digital Base Terminal Block CompactBlock LDX I/O 9 Mount the Optional Expansion Block To mount the optional expansion block, use these steps. 1. Mount the expansion block by connecting it to a previously-installed CompactBlock LDX I/O base or expansion block. 2. Beginning with the base block, mount your expansion block either horizontally or vertically. • To mount horizontally (left to right), add an expansion block in an end-to-end configuration. 44372 Right Side Up • Right Side Up Right Side Up Right Side Up To mount vertically (up or down), add an expansion block either up or down in a back-to-back configuration. In this configuration, you must use the optional 15 cm (5.9 in.) ribbon cable, catalog number 1790-15CMCBL, and alternately position the block in a right-side up, upside-down fashion. Right Side Up The longer expansion cable, catalog number 1790-15CMCBL, provides for up to 7 cm (2.76 in.) of space between blocks. Upside Down Right Side Up 44373 3. Mount your block on a panel or DIN rail.

Publication 1790-IN012C-EN-P - January 2015 DeviceNet Digital Base Terminal Block CompactBlock LDX I/O 15 Interpret the Status Indicators Read this section for information about how to interpret base block status indicators. The base block has these status indicators: • Block status • Network status • I/O status If a module status indicator is flashing red, refer to the cable break procedures section. Status Indicators Indicator Status Description Module Solid red Unrecoverable fault in base unit. Replace base block. Flashing red Fault in expansion unit, or Node address switches do not match current node address. Reconnect or replace, as needed. Solid green Normal operation. Off No power. Apply power to device. Solid red Module node number is a duplicate of an existing node, or network communication issues exist. Change module node number to an unused address, or verify network wiring is correct and communication is stable. Flashing red An I/O connection has timed out. Cycle power to the module. 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. Network Publication 1790-IN012C-EN-P - January 2015 16 DeviceNet Digital Base Terminal Block CompactBlock LDX I/O Status Indicators Indicator Status Description Network 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. Wait until the module has completed the dup_MAC_id test or power the module. I/O Status Indicators Indicator Status Description Each output None Output is not energized. Green Output is energized. None No valid input is present. Green Valid input is present. Each input 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.

Frequently asked questions
You can set the node address using the rotary switches on the front of the base block. Each block has its own 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.
The base block requires a 24V DC nominal supply voltage, with a voltage range of 10…28.8V DC.
The CompactBlock LDX I/O is designed for use in industrial environments with a temperature range of 0…60 °C (32…140 °F) and a relative humidity of 5…90% non-condensing.
