EVENT Task Trigger on UD70

The EVENT task is a high priority task in the UD70 that can be triggered
either by the timer/counter unit, or by the DeviceNet network.
When the fieldbus network is selected as the trigger source, the EVENT
task is triggered in every DeviceNet network cycle.

Care must be taken not to put too much code in the EVENT task. It has
a higher priority than all other UD70 tasks except the INITIAL task, so
an extended EVENT task could easily prevent the SPEED task from
running, and cause the UD70 to trip on "tr54".
NOTE
This feature is only available with system file V2.07.06 or later.

Multi-Master Networks

DeviceNet networks can operate with more than one master device
connected to the same lines. Commander SE, Unidrive and Mentor II
DeviceNet interfaces can all operate on multi-master networks, but
each device can only be assigned to one of the master devi c es.
Consult the supplier of your master controller for more details about
implementing multi-master DeviceNet networks.

Supported Drive Profiles

Class: 41 (0x29)
Class: 41 (0x29)
The input (attribute 101) and output (attribute 100) assembly objects are
set in the Control Supervisor. The default assembly objects are the
Control Techniques Input (106) and Output (107) objects, which allow
each data word to be mapped using #20.PP parameters.
section 5 for more details.
The DeviceNet specification includes a series of set profiles for different
devices, including Drives, and the Unidrive DeviceNet interface
supports several of these pre-defined assembly objects. The format of
the DeviceNet pre-defined assembly objects is fixed.
