Process data acquisition blocks
A maximum of 24 process data can be configured for each display device
(OP2 or VD1). A process data acquisition block must be configured for
each process data. Using a block, the same process data of several
display devices can be simultaneously assigned under the same process
data number.
•
DIS
Reference to the display system configured by @DIS.
•
ST1, ST2
USS station addresses of the display devices at which the process
data can be selected.
•
KEY
Process data number under which the process data can be displayed
at the display device (for OP2, keys V1 to V12).
•
NAM
Name of the process data at OP2. If nothing is specified here, the
following is displayed on OP2: "SIGNALnn".
•
MIN, MAX
Minimum and maximum to limit the input for the setpoint acquisition
blocks.
•
FOR
−
only for the real data types and SDTIME: Number of decimal
places which are displayed at the OP2.
−
for older OP2 versions, information is always displayed to seven
decimal places and exponents which can be divided by three.
The connection attribute, scaling factor and units at inputs and outputs of
real data types (DISA.X and DISS.Y), are taken into account at the
display device.
There are twelve various process data acquisition blocks for display
devices:
•
Six for setpoints
