Programming Function Blocks and Features
BCD
Converts up to 8 discrete inputs' binary coded decimal into an unsigned integer and output the integer as
CVn OV. For example, 00000100 = 4.
On the VPR, when the enable is triggered, the setpoint program specified by the value of CVn OV is copied
from internal storage to the Profile function block(s) where the profile(s) can be programmed or executed.
Table 4-31 describes the BCD prompts. See Table 4-2 for additional prompts.

VPR Example #1, loading a 2-profile program
You are programming a 2-programmer instrument. According to Table 4-32, a 2-programmer instrument
can run 2 profiles at a time and can store in its internal memory up to 6 programs, each containing 2
profiles.
Suppose the BCD bits are programmed as follows: Bit 2 = 1, Bit 1 = 1, Bit 0 = 0. This sequence of bits
equals the number 6 and is the value of CVn OV. When the Enable discrete is triggered ON(1), the profiles
in Program #6 will be loaded from internal memory into the function blocks for Profile #1 and Profile #2,
where they can be edited or run.
VPR Example #2, loading a 4-profile program
You are programming a 4-programmer instrument. According to Table 4-32, a 4-programmer instrument
can run 4 profiles at a time and can store in its internal memory up to 3 programs, each containing 4
profiles.
Suppose the BCD bits are programmed as follows: Bit 2 = 0, Bit 1 = 1, Bit 0 = 0. This sequence of bits
equals the number 2 and is the value of CVn OV. When the Enable discrete is triggered ON(1), the profiles
in Program #2 will be loaded from internal memory into the function blocks for Profiles #1 through #4,
where they can be edited or run.

Definition
Displayed output value will be clamped and will flash when
these limits are exceeded.
The binary coded decimal represented by the states of these
discretes will be converted into an unsigned integer. BIT 7 is
the most significant bit and BIT 0 is the least significant bit.
On the VPR, when this discrete transitions from off(0) to
on(1), the specified program's profile(s) will be loaded from
internal memory to the Profile function block(s). See
Table 4-32.
