Demo3D.PLC.Comms.Memory Namespace |
The Demo3D.PLC.Comms.Memory namespace provides features to access PLCs which expose a memory-based protocol or API.
Classes| Class | Description | |
|---|---|---|
 | DirectMemoryAccessService |
Extension methods for IDirectMemoryAccessService.
|
| MemoryAccess |
Access to PLC memory. May implement INotifyDataChanged, depending on the service.
|
| MemoryAccessChangedEventArgs |
An event reporting a change in data for a particular address.
|
| MemoryAccessesChangedEventArgs |
An event reporting a change in data across a list of addresses.
|
| MemoryAddressChangedEventArgs |
An event reporting a change in data for a particular address.
|
| MemoryPartitioning |
A description of the partitioning of PLC memory.
|
| MemoryService |
A class containing extension methods for IMemoryService.
|
| SequentialVectoredRead |
A helper class for implementing InternalReadV(IReadOnlyListVectoredMemoryRequest).
|
| SequentialVectoredWrite |
A helper class for implementing InternalWriteV(IReadOnlyListVectoredMemoryRequest).
|
| VectoredMemoryAccess |
A vectored memory access.
|
| VectoredMemoryRequest |
A vectored memory request.
|
Interfaces| Interface | Description | |
|---|---|---|
 | IDirectMemoryAccessService |
PLC memory client service.
|
| IDirectMemoryService |
Protocol service for providing direct access to the memory in a peer (bypassing any caches).
|
| IMemoryPartitioningService |
A centralised service for recording how PLC memory should be accessed.
|
| IMemoryService |
Protocol service for providing access to the memory in a peer.
|
| INotifyDirectMemoryAccessService |
PLC memory client service for servers that can notify when memory changes.
|
| INotifyMemoryService |
Protocol service for providing access to the memory in a peer that will notify when the data at the address changes.
DataChanged callbacks will pass MemoryAccessesChangedEventArgs.
The MemoryAccess returned from GetAddress(IAddress, AccessParameters, Object)
implements INotifyDataChanged which will pass MemoryAccessChangedEventArgs.
