All, sorry for two posts… apparently there is no method for attaching a document to a Discus post. Regards, B.Carr

Reviewed definition of ITIDs 0xF899 Energy Storage System Depth of Discharge Counter (Lifetime) and 0xF89A Energy Storage System Tracking Tables.
| Detail | DID Data Size (byte) | Scenario 1 | Scenario 2 | Scenario 3 | Scenario 4 | Scenario 5 | Scenario 6 | Scenario 7 |
|---|---|---|---|---|---|---|---|---|
| Max value for ITID 0xF899, data A-P | 2 | 65535 | 65535 | 65535 | 65535 | 65535 | 65535 | 65535 |
| Set range value(s) for ITID 0xF89A, data C | 1 | 25 | 50 | 60 | 70 | 80 | 90 | 95 |
| Size of Range Array??? | n/a | 2621.40 | 1310.70 | 1092.25 | 936.21 | 819.19 | 728.17 | 689.84 |

Questions:
- Does the ST display 0xF899 data A,B etc. as a straight conversion (y=x)?
- Does the ST display 0xF899 data divided by 0xF89A?
- Does the ST display the “range” data provided by 0xF89A as a static value?

Specific comments to J1979DA:
- Cell C634 text shown in the cell should be bold text.
- Cell C643 text shown in the cell should be bold text.
- Cells C644 thru C651 - what is “R” in “RESS*” when the description is Energy Storage. Should this text string start with “ESS*”?
- Cells C644 thru C651 - what is “L” in “*L:”? If this is for “length”? Is this character needed?
- Cells C644 thru C651 - the format shown is XXXXXXXXXX cnts, or 10 places. The max data size is 5 places (65535). Maybe there is a reason for the 10 places? Seems like the format should indicate 5 places.
- Cells E644 thru E651 - The recommended display strings are super long. The following table is offered for consideration:
| From: | To: |
|---|---|
| RESS_CNTS_DOD_RNG1-L: XXXXXXXXXX cnts | ESS_DOD_RNG1: XXXXXXXXXX cnts |
| RESS_CNTS_DOD_RNG12-L: XXXXXXXXXX cnts | ESS_DOD_RNG1-2: XXXXXXXXXX cnts |
| RESS_CNTS_DOD_RNG23-L: XXXXXXXXXX cnts | ESS_DOD_RNG2-3: XXXXXXXXXX cnts |
| RESS_CNTS_DOD_RNG34-L: XXXXXXXXXX cnts | ESS_DOD_RNG3-4: XXXXXXXXXX cnts |
| RESS_CNTS_DOD_RNG45-L: XXXXXXXXXX cnts | ESS_DOD_RNG4-5: XXXXXXXXXX cnts |
| RESS_CNTS_DOD_RNG56-L: XXXXXXXXXX cnts | ESS_DOD_RNG5-6: XXXXXXXXXX cnts |
| RESS_CNTS_DOD_RNG67-L: XXXXXXXXXX cnts | ESS_DOD_RNG6-7: XXXXXXXXXX cnts |
| RESS_CNTS_DOD_RNG7-L: XXXXXXXXXX cnts | ESS_DOD_RNG7: XXXXXXXXXX cnts |
