MDS type (Tag type)
This value is identical to the specification of the
MDS type with the Format command on a SIMATIC.
Gross MDS size (Tag whole size)
The size of the MDS which was set with the Format
command is indicated.
ECC
Indicates whether the MDS is used with or without
ECC
MDS (Tag)
Indicates the name of the MDS which was written to
the MDS with the Format command
MDS size (Tag size)
Indicates the maximum memory area which can be
used by the user
Bytes free
Indicates the number of data bytes on the MDS
which the user can still use for his/her data

Battery 1 (Bat1)
Status of the RAM battery. This value does not ap-
ply to the EEPROM MDS.
Battery 2 (Bat2)
Status of the dialog battery with MDS 507
Amount of processing (Work Counter)
Number of processing procedures which were per-
formed with the MDS since it was initially formatted.
This value is particularly important for the EEPROM
MDS since the number of write-accesses is limited
for these types of memory.
ECC Correct
Counter for the number of ECC offsets performed.
If this counter has a value other than zero, the MDS
must be replaced in the near future. An EEPROM
memory was write-accessed too often.
