DeviceNet Profile

The IntelliVAC Plus is defined within the “miscellaneous device”

object class; however, extended functions may be required compared

to devices currently included in this class. It will have the following

c apabilities w ith res pec t to DeviceNet:

• Slave operation, with Master (scanner) devices

• Peer-to-peer messaging (Explicit, I/O)

• Explic it Mes s aging

• I/O Messaging (Bit-Strobe, Poll Command/Response, Change of

State/Cyc lic and Multic ast Poll)

Compatibility with IntelliCENTER

The IntelliVAC Plus is c ompatible w ith IntelliCENTER softw are.

This will include the “PCP Object”, as used by t he IntelliCENTER

software to define attributes related to a device.

It shall be possible for IntelliCENTER to properly display the type of

contactor controlled by the IntelliVAC by reading IntelliVAC

parameters.

DeviceNet Communications Loss

With a loss of the DeviceNet communications, the IntelliVAC Plus

module has a selection of two modes to define its operation for

DeviceLogix. To accomplish this, a parameter will be used. This

parameter will have two selectable options: ‘Hold State’ and ‘Reset’.

Selection of the DeviceNet communications loss parameter will be as

follow s:

Select DeviceNet Loss = ‘ ‘Hold State’ or Reset State’

The DeviceNet communications loss parameter will be available on

DeviceNet in the following manner:

DeviceNet Loss = ‘ ‘Hold State’ or ‘Reset State’

Hold State will cause all DeviceLogix outputs to maintain their last

operating state.

Reset State will cause all DeviceLogix outputs to reset to their

default state.
