Capacity of internal memory
Depending on parameter settings (DLXPARA) the individual areas of inter-
nal memory have the following capacity:
Device parameters:
1 set of parameters
Spontaneous events:
Min. 780
Resets (billing data):
Min. 20 (depends on the number of defined input
channels and totals)
Registration period Tm1: Min.

where:
No. of bytes in Tmx:
4: for values with 4 stored digits
6: for values with 6 or 8 stored digits
No. of sectors in Tmx: Round (memory share for Tmx x 9)
(depends on the parameters for internal memory
shares in DLXPARA)
e.g. memory share for Tm1 = 56%
→
No. of sectors in Tm1 = 5.
No. of entries in Tmx:
1..32
(depends on the parameters for storage alloca-
tion: number of inputs, totals, apparent demand
and cos(
ϕ
) in registration period Tm1 or Tm2)
Due to the composition of FLASH memory devices a minimum of sec-
tors of 65536 Bytes each is allocated to each area (the exception be-
ing the device parameters with 1 sector). When registration period
Tm2 is disabled, no sectors will be reserved for the second periodic
buffer (using 100% for Tm1). The spare sector used for internal sector
management is in this case used for the Tm1 buffer (thus “memory
share for Tm1” is set to 10).
