This 1792 ArmorBlock I/O block module (Cat. No. 1792-IB8) contains I/O circuits, a built-in power supply, and a built-in DeviceNet I/O adapter. Because of its sealed housing, this 1792 I/O block requires no enclosure. It is compatible with PLC or SLC programmable controllers using DeviceNet scanners. The I/O values are accessible from the PLC or SLC programmable controller data table.

This ArmorBlock module has no switches to set. You set module parameters using the DeviceNet Manager Software (cat. no. 1787-MGR) or similar configuration tool.

ArmorBlock is a trademark of Allen-Bradley Co. Inc.

Install Your ArmorBlock Module

Installation of the ArmorBlock module consists of:

• setting the node address in the ArmorBlock module

• mounting the ArmorBlock module

• connecting the wiring

• communicating with your module

• configuring the parameters

Set the Node Address

Each ArmorBlock comes with its internal program set for node address

63. To set the node address, you need the following:

• host computer with DeviceNet Manager Software (or similar

configuration software tool)

• 1770-KFD RS-232 module (or similar interface)

• suitable cables to connect the 1770-KFD to your module and to

connect the 1770-KFD to your host computer

Set the node address to meet your system requirements as follows:

1. Set up a system (as shown below) to communicate with your

ArmorBlock module.

2. Using DeviceNet Manager Software, go online using the “Setup

Online Connection” selection on the utility pulldown menu.

3. The DeviceNet Driver selection screen appears.

Select the driver for your application and click on .

4. The Driver configuration screen lets you:

• set the data rate

• set the interface adapter node address

• select the interface adapter serial port

• set interface adapter baud rate

Click on to go online.

ArmorBlock 8 Input Module

5. The bar at the bottom of the screen will tell you when you go online.

6. At the utility pulldown, select “Node Commissioning.”

7. You can set the node address on the “Device Configuration – Node

Commissioning” screen. Note that the node address “out of the box” setting is 63. Set the desired node address per your system requirements.

Set new node address here.

You can also set the data rate on this screen, if required. However, your module is shipped with the “autobaud” parameter enabled. This assures that the module will be at the correct data rate for any network to which it is connected. To change the data rate, you must first disable autobaud on the parameter screen, then return to the “Device Configuration – Node Commissioning” screen and enter the new data rate.

8. Click on

to apply the new node settings.

9. Repeat the above procedure to set the node addresses of any

additional ArmorBlock modules you want to install.

Mount the ArmorBlock Module

Mount the block module directly to the machine or device. Complete mounting dimensions are shown below. Note that the block dimensions allow direct connection of a T-port tap (cat. no. 1485P-P1N5-j) to the DeviceNet connector. (Refer to publication 1485-6.7.1 for cabling details.)

The ArmorBlock module has a sloping top and a gap at the rear to allow water or other liquids to run off during washdowns. The flow through the gap prevents buildup of debris under the block.

Preferred mounting position is with the microconnectors pointing down. However, the block can be mounted in any orientation.

DeviceNet mini connector

Connect the Wiring to the ArmorBlock Module

The block module uses quick disconnect, screw-on style connectors for:

• I/O input wiring

• the DeviceNet connector

8 micro connectors for signal wiring

Micro plugs are included with your module. Use these plugs to cover and seal unused ports.

Pinout diagrams for these connectors are shown below.

ATTENTION: All connectors must be securely tightened to properly seal the connections against leaks

and maintain NEMA 4X and 6P requirements.

Connecting the Input Wiring

Connect input wiring to the micro connectors which screw into mating connectors on the side of the block.

Make connections as shown below.

Communicate with Your ArmorBlock Module

This ArmorBlock module acts as a slave in a master/slave environment. It is both a “polled device” and a “change of state device.”

When configured as a polled device, a master initiates communication by sending its polled I/O message to the ArmorBlock module. The 8 input module scans the inputs and fault bit producing a response that reflects their status.

When configured as a “change of state” device, productions occur when an input changes or an input source voltage fault occurs. If neither has occurred within the “expected packet rate,” a heartbeat production occurs. This heartbeat production tells the scanner module that the ArmorBlock module is alive and ready to communicate.
