DI Function Block
General
An FVP110 contains two DI function blocks, which individually transfer the valve-position
high and low limit switch signals generated by the transducer block (Figure 60).
Figure 60 Inputs/Outputs of DI Function Block
The major functions of a DI function block include (Figure 61):
❑ Signal inversion (I/O processing option)
❑ Simulation
❑ Filtering (time delay)
❑ Alarm generation
