Parameters
List of Parameters
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, p3900, p3981
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.
p0015 Macro drive unit / Macro drv unit
CU240B-2 Access level: 1
CU240E-2
Can be changed: C, C(1)
CU240E-2 F
Units group: -
Min
0
Description: Runs the corresponding macro files.
The selected macro file must be available on the memory card/device memory.
Example:
p0015 = 6 --> the macro file PM000006.ACX is run.
Dependency: Refer to: p0700, p1000, p1500, r8570
Caution: When executing a specific macro, the corresponding programmed settings are made and become active.
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 macros in the specified directory are displayed in r8570. r8570 is not in the expert list of the commissioning
software.
Macros available as standard are described in the technical documentation of the particular product.
The parameter is not influenced by setting the factory setting.
