5.3.6 Multiple Analog Input block
The Multiple Analog Input block scales up to eight electrical input signals of 4 mA to 20 mA or
1 mV to 5 mV to
OUT_x values of 0% to 100%. The block can be used together with the SFC444
and SFC457 analog input modules. If other input signals are used with these modules, Analog Input
blocks must be used.

Procedure 1 In the fieldbus view, right click on the Multiple Analog Input block Device Tag-MAI-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+ 9 )
– Click on End Edit
Properties The input channels of the SFC444 and SFC457 can be configured individually by jumpers on the
printed circuit board to accept current or voltage signals, default setting current, see Chapter 3.5.1
of operating instructions BA021S/04/en, Field Controller: Hardware Installation. The OUT value
is proportional to the electrical signal over the range 0 mA to 40 mA and 0 V to 10 V. The MAI
block converts the input as shown in Table 5-2.
