2.4 Changing values
2.4.1 Differentiating between values (data classes)
The methods of entering and changing values differ depending on the value. These are
therefore subdivided into so-called "data classes" (abbreviation: "DC"). Values in the same
data class are treated identically during entry. A prerequisite for an entry is that the lock
assigned to the value is open.
The following data classes (DC) are present in the TC210:
DC
Type Entry, change using "ENTER"
1
Display test No change possible.
2 Function Function is initiated by pressing the key for at least two seconds.
3
Constant No change possible.
4 Measurement The value is updated by pressing the key for at least two seconds.
5 Status No change possible.
7
Discrete value When the key is pressed for at least two seconds, the value can
be changed by using the key to select from a list of possible val-
ues.
8 Permanent
value No change is possible using the keypad on the device.
11 Combination Changes possible on the device, but with masked entry, i.e. only
the character currently being edited is visible, all others are
masked out by a minus sign.
With a closed lock it is opened on entering the correct combina-
tion.
With an open lock, the combination is changed by the entry.
12 Counters As "Permanent value" (see above.).
15 Computation
counter No change possible.
16 Initial value No change possible, sometimes branching to a submenu.
19
Status register No change possible.
If a value is accommodated in a submenu, it cannot be changed independent of its data
class by the keypad, since pressing the key for at least two minutes then results in branch-
ing into the submenu.
