Parameter value as an integer input
How the block handles the input
The block reads the selected value in as an integer.
Note:
The parameter selected as an input should be an integer value. The internal scaling for each parameter is
available in chapter
Parameters
.
How to select the input
−
Scroll to the input selection parameter of the block and switch to edit mode (Enter).
−
Set the address, from which the input value is to be read, with group * 100 + index, e.g. AccTime1 (22.01)
== 2201. A negative address (e.g. -2201) will act an inversion of the connected value.
The figure below shows the DCS Control Panel display when Block1In1 (84.05) is in edit mode:
Example:
AI1 is supplied with a voltage source of 5.8 V. Connect AI1 to the block as follows:
−
Scroll to Block1In1 (84.05) and shift to edit mode (Enter). Set to 503, because the value of AI1 is shown in
group 5 with index 3 - AI1 Val (05.03) == 05 * 100 + 3 = 503.
−
The value at the input of the block is 5800, since the integer scaling of AI1 Val (05.03) is 1000 == 1 V see
chapter
Parameters
.
Constant as an integer input
How to set and connect the input
Option 1:
−
Scroll to the input selection parameter of the block and switch to edit mode (Enter).
−
Give the constant value to this input parameter (arrow keys).
−
Accept with Enter.
−
Scroll to attribute parameter, e.g. Block1Attrib (84.08).
−
Set the bit for constant attribute of this input in Block1Attrib (84.08).
−
Accept by Enter.
The constant may have a value from -32768 to 32767. It is not possible to change the constant while AP is
running. The figures below shows the DCS Control Panel display when Block1In2 (84.06) is in edit mode and
the constant field is visible:
