3.8.4 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 Tm

Tm1) in entries of No. Tm1 in bytes of (No.12
65522Tm1 in sectors of No.

Registration period Tm

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).
