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).
The major functions of a DI function block include (Figure 61):
❑
Signal inversion (I/O processing option)
❑
Simulation
❑
Filtering (time delay)
❑
Alarm generation
