Output microblock varies the width of
the pulse based on the value that the
microblock receives.

Output N/A N/A
1 The Analog Output microblock uses the Min and Max values to linearly translate its incoming value into a
physical output signal (Volts) sent from the TV-VVTBP-E2 to a device. For example, set Min to 0 and Max to 100
for an Analog Output microblock that receives a 0 to 100% open signal from a PID microblock and that controls
a 0
– 10 Vdc actuator so that when the PID signal is 100%, the TV-VVTBP-E2 output is 10 Vdc. Similarly, when
the PID signal is 50%, the TV-VVTBP-E2 output is 5 Vdc.
Resolution values
Resolution is not particular to a type of input or output, but the driver handles analog and binary inputs and
outputs differently. To set these values appropriately, you should understand how the driver uses them.
Resolution Notes
Analog Input (BAI) The driver rounds the microblock's present value according to the resolution.
EXAMPLE If the calculated present value is 13.789 and you set the Resolution to 0.1, the
control program uses 13.8 for any calculations downstream from the microblock.
Analog Output
(BAO) The driver rounds the wire input value to the microblock before performing any scaling
calculations.
EXAMPLE If the wire input value is 13.789 and you set the Resolution to 0.1, the
microblock uses 13.8 for any scaling calculations.
