Publication 1790-IN007C-EN-P - May 2006 6 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/networks/eds/. EDS files for blocks with matching catalog numbers for both D-Shell and terminal block versions are the same. On the Web site and in RSNetWorx for DeviceNet software, find 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. Install the Base Block To install the base block, follow these steps. 1 . Set the node address on the base block. 2. Mount the base block. 3. Mount the optional expansion blocks. 4. Wire the terminal block. 5. Connect the DeviceNet cable. Publication 1790-IN007C-EN-P - May 2006 DeviceNet Digital Base D-Shell Block CompactBlock LDX I/O 7 Set the Node Address 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 between 00 and 63. 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. Publication 1790-IN007C-EN-P - May 2006 8 DeviceNet Digital Base D-Shell Block CompactBlock LDX I/O Mount the Base Block Mount the base block to a panel or DIN rail. We recommend that you ground the panel or DIN rail before mounting the block. IMPORTANT The analog base module can accommodate a maximum of two digital expansion modules. Mount on a Panel For panel mounting, use these steps. 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. Publication 1790-IN007C-EN-P - May 2006 DeviceNet Digital Base D-Shell Block CompactBlock LDX I/O 9 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. 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. Mount the Optional Expansion Block Mount the expansion block by connecting it to a previously-installed CompactBlock LDX I/O base or expansion block. Publication 1790-IN007C-EN-P - May 2006 10 DeviceNet Digital Base D-Shell Block CompactBlock LDX I/O Beginning with the base block, mount your expansion block either horizontally or vertically. 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 • To mount horizontally (left to right), add the expansion block in an end-to-end configuration. • 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 (1790-15CMCBL) and alternately position the blocks in a right-side up, upside-down fashion. Mount your blocks on a panel or DIN rail. Wire the TD-Shell Connectors 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. Be sure that power is removed or the area is nonhazardous before proceeding.

Publication 1790-IN007C-EN-P - May 2006 14 DeviceNet Digital Base D-Shell Block CompactBlock LDX I/O 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. • 1799-DNETCON - 5-position open style connector • 1799-DNETSCON - 5-position open style connector with locking screws • 1799-DNC5MMS - 5-position open style to 12 mm connector with locking screws 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. Publication 1790-IN007C-EN-P - May 2006 DeviceNet Digital Base D-Shell Block CompactBlock LDX I/O 15 1 .

Publication 1790-IN007C-EN-P - May 2006 16 DeviceNet Digital Base D-Shell Block CompactBlock LDX I/O 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 Indication Probable Cause Recommended Action Solid Red Unrecoverable fault in base unit. Replace base block. Flashing Red Fault in expansion unit. Replace expansion unit. Solid Green Normal operation. None. 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. Module Status Network Status Publication 1790-IN007C-EN-P - May 2006 DeviceNet Digital Base D-Shell 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. Wait until the module has completed the dup_MAC_id test or power the module. Function LED Color Module Illumination Condition Outputs Each output: Green None Green Output not energized. Output energized. Inputs Each input:: Green None Green No valid input. Valid input. I/O Status Publication 1790-IN007C-EN-P - May 2006 18 DeviceNet Digital Base D-Shell Block CompactBlock LDX I/O Cable Break Procedure A cable break in any location between either of the following produces data of 1 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 turn on 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. To determine if the data is valid, continuously send an explicit message to the module to check the status of the input conditions since no status word is in the I/O mapping data table. • Class = 1 • Instance = 1 • Attribute = 101 (0x65) To detect the loss of communication to the expansion module, use one of these methods. • If an unused input is available, tie the unused input on the last expansion low. If that input goes high with a value of 1, a loss of communication to the expansion or expansions occurred. • If no unused input is available, check expansion inputs for the condition of all on. To check validity in this case, send an explicit message to the identity object class 1, instance 1, attribute 101 (0x65). A returned value of 0 indicates the input data is good.
