PROGRAMMING THE INPUT/OUTPUT SWITCHES
Each LVDT simulation bank has switches on the inputs and output to enable short and open circuit conditions
for fault simulation. Also switching is included for interconnecting inputs so that a common excitation signal can
be shared between channels. These switches can be controlled graphically using the Soft Front Panel, or the
corresponding bits can be set via the appropriate sub-unit using the module’s driver. The sub-unit and bit allocations
for these switches is summarized in the following table and in Figure 4.15.
