Figure B.1 Bit-Strobe Command
The XM modules use the bit received in a Bit-Strobe connection as a trigger
event. When the bit number corresponding to the XM module’s node address
is set, the XM module will collect the triggered trend data.
Note that the XM modules do not send data in the Bit-Strobe response.
ADR for XM Modules
Automatic Device Replacement (ADR) is a feature of an Allen-Bradley
DeviceNet scanner. It provides a means for replacing a failed device with a
new unit, and having the device configuration data set automatically. Upon
replacing a failed device with a new unit, the ADR scanner automatically
downloads the configuration data and sets the node address.
IMPORTANT
It is recommended that ADR not be used in safety related
applications. If the failure of the ADR server, and a subsequent power cycle, would result in the loss of protection for
a machine, then ADR should not be implemented.
ADR can be used with XM modules but keep the following in mind when
setting up the XM modules.
