5.3.3 Analog Input block
The Analog Input block is fully configurable and provides characterization for the incoming signal.
The
OUT value has the range and units configured in the OUT_SCALE parameter.
Fig. 5-2 Schematic diagram of Analog Input block
Procedure 1 In the fieldbus view, right click on the Analog Input block Device Tag-AI-n and select Off
Line Characterization . The Characterization dialog opens.
– Press the ALL button in the toolbar to display all parameters
2 Expand the MODE_BLK node and set the Target Mode to Auto
– Select the Target node then click the Edit button
– Select Auto from the drop-down menu, click End Edit to confirm the selection
– Click Close to leave the dialog.
3 Set CHANNEL to the input connected to the block as defiined in Section 5.3.1
– Select CHANNEL , then click the Edit button
– Enter the CHANNEL value (Rack+Slot+Group+Point)
– Click on End Edit
4 Set L_TYPE to "Indirect" or "Indirect Sq Root" (for
∆
p flow analog input)
– Select L_TYPE , click the Edit button, select parameter , then click on End Edit
5 Expand XD_SCALE and set the parameters according to the signal from the input point.
– EU_100 is the upper range limit of the input signal, e.g. 20
– EU_0 is the lower range limit of the input signal, e.g. 4
– UNIT_INDEX is the unit of the input signal, e.g. mA
– DECIMAL is the number of figures behind the decimal point
In each case click the Edit button, enter or select parameter , then click on End Edit
For the SFC445 Temperature module, the ranges and units are listed overleaf.
6 Expand OUT_SCALE and set the parameters according to the signal to be output.
– EU_100 is the upper range limit of the output signal, e.g. 100
– EU_0 is the lower range limit of the output signal, e.g. 0
– UNIT_INDEX is the unit of the output signal, e.g. %
– DECIMAL is the number of figures behind the decimal point
In each case click the Edit button, enter or select parameter , then click on End Edit
7 For flow measurements a low-flow cut-off limit can be set as follows:
– Select the IO_OPTS parameter and click on Edit
– Select the Low Cut-Off option and click End Edit
– Select the CUT_OFF parameter, click on Edit , enter the limit in OUT_SCALE units
– Click on End Edit .
