Communicate With Your ArmorBlock LP2 Module
This ArmorBlock module’s I/O is exchanged with the master through a
polled, 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 16 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 website at http://www.ab.com/networks for producer/
