4.4.8MAC ID

The MX-DeviceNet unit may have the MAC ID set by one of two different methods. The first is the MX LCD display. The other is via the DeviceNet bus.

4.4.9Baud Rate

The MX-DeviceNet unit may have the Baud Rate set by one of two different methods. The first is the MX LCS display. The other is via the DeviceNet bus.

4.5Network Management

4.5.1Offline Connection Set

NOTE: The DeviceNet Limitorque Interface supports Offline Connection Set. The Offline Connection Set is used to bring back a node to the DeviceNet bus which is in the Communication Fault State. This state will be entered in the case of a duplicate MAC ID error is detected.

4.5.2Device Heartbeat Message

The DeviceNet Limitorque Interface supports Device Heartbeat message. This message broadcasts the current state of the DeviceNet Limitorque Interface. Table 4.42 shows the format of the data field of the Device Heartbeat Message.

EV  Event Flag, zero (0)

 

SF  System Fault, a fault in the device caused by DeviceNet bus interaction (e.g. connection timeout).

 

This flag is set, when a system fault is present. This DeviceNet Limitorque Interface flag is set when a

 

connection times out.

 

UF  User Fault, a fault in the device caused by user interaction. This flag is set when a user fault is

 

present. The conditions under which is set are vendor specific. This DeviceNet Limitorque Interface flag

 

is not used and is zero (0).

34

DF  Device Fault, an internal fault in the device not caused by user or bus interaction (e.g. hardware

 

fault). This flag is set when a device fault is present. This DeviceNet Limitorque Interface flag is set

 

under the following conditions:

• (DI_Actuator_Faults_1_Chan ≠ 0) OR (DI_Actuator_Faults_3_Chan ≠ 0)
