P0559 – Maximum Trace Memory
Adjustable Range:
0 to 100 %
Factory Setting:
0 %
Properties:
Groups of
01 PARAMETER GROUPS
Access via HMI:
41 Trace Function
........
Description:
It defines the quantity of memory the user wishes to set aside for points of the Trace function. The adjustable
range, from 0 to 100 %, corresponds to requesting the reservation of 0 to 15 Kbytes for the Trace Function.
Each point stored by the function takes two bytes in the memory of the CTW900. This parameter defines,
indirectly, the maximum number of points the user can store by means of this function.
The memory area used by the Trace function is shared with the memory for the SoftPLC application. When
there is an application of the SoftPLC on the converter, the quantity of memory really available for the Trace
function can be smaller than the value set in P0559. The indication of the quantity of memory effectively
available is done in the reading parameter P0560.
NOTE!
As factory setting, the memory available for the Trace function is totally directed to the SoftPLC
applications (P0559 = 0 %). Therefore, when you wish to use this function, it is necessary to set
P0559 to a value different from 0 %.
P0560 – Memory Available for Trace
Adjustable Range:
0 to 100 %
Factory Setting:
0 %
Properties:
RO
Groups of
01 PARAMETER GROUPS
Access via HMI:
41 Trace Function
........
Description:
It shows the quantity of memory available to store points of the Trace function. The variation range, from 0 to
100 %, indicates that from 0 to 15 Kbytes are available for this function.
Sharing of the memory with the SoftPLC
The memory for the Trace function is shared with the memory for the SoftPLC applications. Thus:
■
if P1000 = 0 (without SoftPLC application), it is possible to use all the memory area for the Trace function. In
this case, P0559 = P0560;
■
if P1000 > 0 (with SoftPLC application on the converter), P0560 will show the remaining area to store data of
the Trace function, discounting the area taken by the SoftPLC application.
NOTE!
If the value of P0560 is smaller than the setting of P0559 and the user wishes to use more memory
for the Trace function, the SoftPLC application must be erased by means of parameter P1001.
