| Summary | 0008060: Non-Volatile Storage | ||||
| Description | we should extend the AccessLevelExType definition with an additional Bit label NonVolatileData, description would be "Indicates that the value is stored in Non-Volatile storage and will be restored on a restart of the server (1 mean Non-Volatile storage is supported). | ||||
| Additional Information | This functionality is commonly available in current controllers and PLC and knowledge of whether a variable is stored in Non-Volatile storage can be very helpful to applications. FLC would utilize this bit in its information model. | ||||

|
|
Agreed states would be 0 == presumed Volatile (i.e. volatile or don't know) FLC needs this soon - target 1.05.01 |
|
|
Added a bit to AccessLevelEx definition. |
|
|
Needs to be rolled back from 1.05.00 and fixed in 1.05.01. |
|
|
Added a bit to AccessLevelEx definition. |
|
|
We agreed to an alternate solution with the three bits named differently and with slightly different meaning. Jim will edit Part 3 and 5 with the new proposal. |
|
|
AccessLevelEx was extended to include 2 new bits (NonVolatile and Constant). |
|
|
Agreed that this is published in 1.05.01. |
|
|
Paul Hunkar thinks we need a new CU for this. |
|
|
I think the conformance unit text should mirror what is described in https://profiles.opcfoundation.org/conformanceunit/51 (Address Space Atomicity) i.e. call it Address Space NonVolatile and Constant. description would "Support setting the NonVolatile and Constant. flags in the AccessLevelEx Attribute for Variable Nodes to indicate whether persistent storage is supported." |
|
|
Created a new CU for NonVolatile and Constant in the profile database (https://profiles.opcfoundation.org/conformanceunit/4056). |
|
|
Agreed to changes in the database. |
