Question:
What kind of reset types are there?
Answer:
From DDS version 2.0 in it is possible to release different types of the reset. They are released via the menu item Online-> Reset, Online-> Reset (cold) or Online-> Reset (origin). The reset types described below refer to the operating system ≥ 6.2 Servo PLC (DSMC) and Drive PLC.
1. Reset
- The RAM variables of the PLC program are set to their initialisation value / to 0, if they have no initialisation value.
- The variable classes Retain and Persistent do not change.
- The user codes are set to the initial value, but they are not stored in the parameter set (they can be restored with C0002 = 1 parameter set load).
2. Reset (cold) PLC program download
- The RAM variables of the PLC program are set to their initialisation value / to 0, if they have no initialisation value.
- The Retain variables are written to 0 / to their initialisation value.
- The Persistent variables do not change.
- The user codes are set to the initial value, but they are not stored in the parameter set.
3. Reset (origin)
- The PLC program does not exist anymore. (User RAM is deleted, user codes do not exist.)
- The Retain and the Persistent variable field is deleted (written to 0).
- The default setting of the system codes is loaded and stored in the parameter set.
- The servo PLC's sectors of the second flash organisation unit are deleted.
4. Special case PLC program download
- The RAM variables of the PLC program are set to their initialisation value / to 0, if they have no initialisation value.
- The Retain variables are written to 0 / to their initialisation value.
- The Persistent variables do not change.
- The user codes are set to the initial value (value from the instance parameter manager) or to entries in the dialogue codes initialisation values (if available) and are stored in the parameter set.
