EDS File Requirements

Current functionality of CompactBlock LDX I/O blocks require current modular EDS file for RSNetWorx for DeviceNet™ version 3.0 or later software.

These files are easy to install and 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. Thus, on the website and in RSNetWorx for DeviceNet, there is only one EDS file for both versions of the blocks. For example, if you want the EDS file for 1790D-T8BV8B, use the EDS file labeled 1790D-8BV8B.

Publication 1790-IN011C-EN-P - January 2015

DeviceNet Base RTD and Thermocouple CompactBlock LDX I/O 5

Example: Node Address is set at 11

Install the CompactBlock LDX I/O

Follow these steps to install the block:

• set the node address on the base block.

• mount the base block.

• wire the terminal blocks.

•connect field wiring.

• connect the DeviceNet cable.

These steps are explained in detail in the following procedures.

Set the Node Address on the Base Block

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 block. The two switches are most significant digit (MSD) and least significant digit (LSD). The switches can be set between 00 and 63.

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.

Node Address Example

The node address may also be set through RSNetWorx for DeviceNet or a similar configuration tool. When software configuration is used for the node address, the switches must be set between 64 and 99.

Mount the Base Module

You can mount the base block to a panel or DIN rail. We recommend that you ground the panel or DIN rail before mounting the block.

The RTD and thermocouple base blocks do not support any expansion blocks.

WARNING: When used in a Class I, Division 2, hazardous location, this equipment must be mounted in a suitable enclosure with the proper wiring method that complies with the governing electrical codes.

Dimensions

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. 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.

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.

System Wiring Guidelines

Follow these guidelines when wiring your system:

• use shielded, twisted pair wire to ensure proper operation and high immunity to electrical noise

• to limit noise, locate RTD and resistance device signal wires as far away as possible from power lines, load lines and other sources of electrical noise, such as hard-contact switches, relays and AC motor drives

• under normal conditions, the drain wire and shield junction should be connected to earth ground, via a panel or DIN rail mounting screw at the block end

• keep shield connection to ground as short as possible

• to ensure optimum accuracy, limit overall cable impedance by keeping the cable as short as possible. Locate the I/O system as close to your field devices as your application will permit.

RTD Wiring Guidelines

Since the operating principle of the RTD module is based on the measurement of resistance, give special consideration when selecting the input cable. For 2-wire or 3-wire configurations, select a cable that has consistent impedance throughout its entire length.

Publication 1790-IN011C-EN-P - January 2015

10 DeviceNet Base RTD and Thermocouple CompactBlock LDX I/O

IMPORTANT

The RTD block requires three wires to compensate for lead resistance error. We recommend that you do not use 2-wire RTDs if long cable runs are required, as it reduces the accuracy of the system.

However, if a 2-wire configuration is required, reduce the effect of the lead wire resistance by using a lower-gauge wire for the cable (for example, use AWG #16 instead of AWG #24). The block’s terminal strip accepts AWG #14 gauge wire.

When using a 3-wire configuration, the block compensates for resistance error due to lead wire length. For example, in a 3-wire configuration, the block reads the resistance due to the length of the wires and assumes that the resistance of the other wire is equal. If the resistance of the individual lead wires are much different, an error may exist. The closer the resistance values are to each other, the greater the amount of error is eliminated.

To ensure temperature or resistance value accuracy, the resistance difference of the cable lead wires must be equal to or less than 0.01 .

To ensure that the lead values match as closely as possible:

• keep lead resistance as small as possible and less than 25 

• use quality cable that has a small tolerance impedance rating

• use a heavy-gauge lead wire which has less resistance per foot

RTD Wiring Configurations

Three configurations of RTDs can be connected to the blocks:

• 2-wire RTD, which is composed of an RTD EXC (excitation) lead wire and a RTN (ret urn) wi re

• 3-wire RTD, which is composed of a Sense and 2 RTD lead wires (RTD EXC and RTN)

• 4-wire RTD, which is composed of a Sense and 2 RTD lead wires (RTD EXC and RTN). The second sense wire of a 4-wire RTD is left open.

Connect the DeviceNet Cable

Follow these procedures when connecting the DeviceNet cable to the base block.

The required DeviceNet connector is not supplied with the block - you must purchase it separately. There are three types of connectors that you can order directly from Rockwell Automation or your local distributor:

• 1799-DNETCON – 5-position open style connector

• 1799-DNETSCON – 5-position open style connector with locking screws

• 1799-DNC5MMS – 5-position open style to 5-pin micro male 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.

1. Connect the DeviceNet wiring (drop line) to one of the DeviceNet connectors as shown in the figure, noting that a color-coded wiring diagram is printed next to the connector on the left side of the base block.

1. Attach the connector to the base block once you have properly wired the drop line to the connector.

2. Use the locking screws on the connector to fasten it to the base block, if applicable.
