max:
Maximum value for the further display on the server (e.g. graphic)
vscale:
Virtual scaling of the value (see "Attributes of the field definition" on page 238).
In the current example the extracted value is multiplied by 0.01.
chmode:
Channel mode
6 =^ analogue channel (a "simple" measurement value, e.g. the temperature)
index:
Is used for the user-defined sorting of the fields in the selection lists
Lines 4-6 describe the third measurement value "Pump" in the measurement data container used:
Pump:
"Pump" should be used as the name for the measurement value.
u8:
The data type used for the measurement value should be an 8-bit unsigned integer
(i.e. 1 byte).
view:
Specifies from which user level the field is visible on the interface of the server
99 =^ field is not visible to anyone (required as in the current example the "Pump_
MSK" shadow field should be used instead of the "Pump" field. Shadow fields can be
used to divide one byte field up into several bit fields).
edit:
Specifies the user level that is required to be able to change the field content via the
interface of the server
99 =^ field cannot be changed by anyone (required as in the current example the
"Pump_MSK" shadow field should be used instead of the "Pump" field).
@Pump:
Specifies that the "Pump_MSK" shadow field defined in line 6 should use the memory
area of the "Pump" field defined in line 4
Pump_MSK:
"Pump_MSK" should be used as the name for the shadow field.
dlorw=skip:
The shadow field is not considered for the access functions to the container which are
automatically generated for the device logic (in the current example histdata channel
0). I.e. within the device logic writing/reading of the shadow field must be done via
manual masking of the desired bit in the "Pump" field.
bitmask:
Bit mask to mask the actual bits to be used out of the data block, hexadecimal
In the current example, the least significant bit (LSB) is masked out of the "Pump" field.
min:
Minimum value for the further display on the server (e.g. graphic)
max:
Maximum value for the further display on the server (e.g. graphic)
chmode:
Channel mode.
1 =^ digital
