5.3.8 Analog Output block
The Analog Output block is fully configurable and provides characterization for the outgoing signal.
The
OUT value is scaled with the PV_SCALE and XD_SCALE parameters.
Fig. 5-7 Schematic diagram of Analog Output block
Procedure 1 In the fieldbus view, right click on the Analog Output block Device Tag-AO-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+Slot)
– Click on End Edit
4 Expand PV_SCALE and set the parameters according to the input signal.
– EU_100 is the upper range limit of the input signal, e.g. 100
– EU_0 is the lower range limit of the input signal, e.g. 0
– UNIT_INDEX is the unit of the input signal, e.g. %
– DECIMAL is the number of figures behind the decimal point for displays
In each case click the Edit button, enter or select parameter , then click on End Edit
5 Expand XD_SCALE and set the parameters according to the signal output by the I/O module
– EU_100 is the upper range limit of the output signal, e.g. 20
– EU_0 is the lower range limit of the output signal, e.g. 4
– UNIT_INDEX is the unit of the output signal, e.g. mA
– DECIMAL is the number of figures behind the decimal point for displays
In each case click the Edit button, enter or select parameter , then click on End Edit
6 Repeat the process for all inputs to AO blocks
