Communicate with Your FlexArmor System
The FlexArmor DeviceNet adapter module supports multiple
communication choices. The network master makes the actual
communication choice. The choices are:
Polled - data is sent by the adapter in response to received data.
Strobe - data is sent by the network in response to the strobe
command. The single bit allocated to the adapter in the strobe
message is not used. If the configured size of the input data (sent
from the adapter) is greater than 8 bytes, the strobe connection
establishment will fail. In this case, the input size must be
re-configured to 8 bytes or less.
Change of State - data is sent by the adapter based on detection of
any changed value within the input data. Data is independently
received based on change of state from the sender. Data in both
directions can be acknowledged or unacknowledged depending on
the run time configuration of the system.
Cyclic - data is sent cyclically by the adapter based on a configured
time value. Data is independently received cyclically from the sender.
Data in both directions can be acknowledged or unacknowledged
depending on the run time configuration of the system.
