High Current 8 Input/8 Output ArmorBlock I/O Module Series B IMPORTANT ATTENTION ! 3 Identifies information that is critical for successful application and understanding of the product. Environment and Enclosure This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to 2000 meters without derating.
High Current 8 Input/8 Output ArmorBlock I/O Module Series B Install Your High Current I/O Module To install the module you must: • • • • • Set the node address Mount the module Connect the cable assembly to the module Connect the DeviceNet cable to the module Communicate with your ArmorBlock I/O module More detailed information about each of these steps is in the following procedures.
High Current 8 Input/8 Output ArmorBlock I/O Module Series B 5 The two switches are: • MSD (most significant digit) • LSD (least significant digit) To reset the node address, use a small blade screwdriver to rotate the switches. Line up the small arrow on the switch with the number setting you wish to use. The rotary switches are read at module power up only. Settings between 64 and 99 cause the module to use the last valid node address stored internally. Example: The last setting was 40.

High Current 8 Input/8 Output ArmorBlock I/O Module Series B 9 Connect the DeviceNet Cable to the Module Connect the DeviceNet wiring to the 5-pin micro-connector on the module. The micro-connector pinout is shown below.
High Current 8 Input/8 Output ArmorBlock I/O Module Series B Change-of-State - productions occur when an input changes or a fault condition occurs. If no input or fault condition change occurs within the expected packet rate, a heartbeat production occurs. This heartbeat production tells the scanner module that the I/O module is alive and ready to communicate. Consumption occurs when data changes and the master produces new input data to the I/O block.
