ArmorBlock LP2 4 Sinking Input Module 5

Communicate With Your ArmorBlock LP2 Module

This ArmorBlock module’s I/O is exchanged with the master through a

poll, change of state, or cyclic connection.

The module produces input data as follows:

Cyclic - allows configuration of the block as an I/O client. The block will

produce its I/O cyclically at the rate configured.

Polled - a master initiates communication by sending its polled I/O

message to the module. The 4 input module scans the inputs producing a

response that reflects their status.

Change of state - productions occur when an input changes . If no input

change occurs within the expected packet rate, a heartbeat production

occurs. This heartbeat production tells the scanner module that the module

is alive and ready to communicate.

Refer to the table below for the word/bit definitions.

The DeviceNet Network uses advanced network technology, producer/

consumer communication, to increase network functionality and

throughput. Visit our web site at http://www.ab.com/networks
