p0014 Buffer memory mode / Buf mem mode
Access level: 3
Can be changed: U, T
Units group: -
Min
0
Description: Sets the mode for the buffer memory.
Value: 0:
1:
2:
Dependency: If p0014 = 1, changes in the same parameter, as well as in following parameters will not be copied to the buffer
memory:
Refer to: p0040, p0340, p0650, p0802, p0803, p0804, p0952, p0969, p0970, p0971, p0972, p1900, p1910, p1960,
p2111, p2380, p3900, p3981, p8400, p8401, p8608, p8611
Refer to: A01066, A01067
Caution: For p0014 = 2, entries in the buffer memory are lost and cannot be retrieved.
Notice: After the value has been modified, no further parameter modifications can be made and the status is shown in
r3996. Modifications can be made again when r3996 = 0.
Note: The parameter is not influenced by setting the factory setting.
Re p0014 = 0:
Parameter changes are saved in the volatile memory (RAM).
Non-volatile storage from RAM to ROM is carried out in the following cases:
- p0971 = 1
- change from p0014 = 0 to 1
Re p0014 = 1:
With this setting, alarm A01066 followed by alarm A01067 can occur if parameters are continually changed via a
fieldbus system.
Parameter changes are entered in the volatile memory (RAM) and also in the non-volatile buffer memory.
In the following cases, the entries in the buffer memory are transferred into the ROM and then the buffer memory is
cleared:
- p0971 = 1
- power down/power up the Control Unit
- change from p0014 = 1 to 0
Re p0014 = 2:
The procedure to clear the entries in the buffer memory is initiated.
p0014 is automatically set to 0 after the entries have been cleared.
