VIM redundancy is now available for DeltaV Serial card emulation. DeviceNet cards are not redundant. The following connection types and data access methods are supported. For more information, please see the online help under VIMNet Explorer.
Class1 Scanner - VIM2 is the scanner initiating sessions with Class1 Adapter devices, e.g., Drives and Overload Relays.
Class1 Adapter - VIM2 is the adapter responding to session requests from a Class1 Scanner, e.g., a ControlLogix PLC.
UCMM Tag access - VIM2 initiates the session to read/write ControlLogix Tags.
UCMM DF1 access - VIM2 initiates the session to read/write data from ControlLogix, MicroLogix, SLC5/xx and PLC5/xx processors using PCCC embedded DF1 messages.
A new reporting mechanism has been added to send field data to DeltaV on a periodic, user configured time interval. When an Input or Output with Readback dataset is specified, the Special Data 1 value can be used to control the rate at which input changes are reported to DeltaV. Users configure the update period in increments of 200 ms. If unconfigured (i.e., default of 0), the VIM2 will report the data to the DeltaV controller as it changes.
The Special Data 1value is the minimum time between reporting the data to the DeltaV controller, specified in 200 ms increments. The dataset values are only reported to the controller when they change. This parameter enforces a minimum time between updates.
For example, if Special Data 1 is 5, the data will not be reported more frequently than once per 1000 ms. The maximum reporting period is 51 seconds.
This feature is useful when the data is changing more frequently than required by the DeltaV controller.
New functionality has been added to Enable/Disable individual connections from the VIMNet Explorer. Right click on the connection to receive this dialog. Click the Disable checkbox and click Update VIM2. The online VIM2 will stop communicating with the field for this connection. Subsequently, deselect the checkbox and click Update VIM2 to resume communications. This feature is useful to remove a device from the scan, for example, if it is going into maintenance mode.
The latest ODVA specification requires that messages be periodically sent to maintain EtherNet/IP Encapsulation Sessions. For all Class1 Scanner connections, the VIM2 will periodically (once a minute) send a Class/Service message to read the field device identity. This prevents the Class1 Adapter from timing out.
