2.2.2.

Reference Voltages

The controller has two user configurable reference voltage outputs. By default, with No Control
Source or the Control Source value set to 0, the Reference Voltage is set to 10V.

When a 5V reference is used, the 5120h

VREF Control Source

and 5121h

VREF Control Number

objects for the reference voltage need to have a non-zero value. For example, setting the “

VRef #1

Control Source

” to “

7 – Control Constant Data

” and “

VRef #1 Control Number

” to “

2 – Control

Constant Data #2

” will configure the reference voltage source #1 as a 5V reference.

Figure 10 – PID Control Objects

As with the output function block, the PID control function has control inputs associate with it that
can be mapped to the output from any other function block. Objects 2453h

PID Target Source

and

2454h

PID Target Number

define what value the PID loop will attempt to maintain. For example, in

the case of a setpoint (fixed) control application, this input can be mapped to one of object 5010h, a
Constant FV. In this case, since there is no pre-defined range associated with a constant, the scaling
limits will be set equal to those of the feedback input. Otherwise, the target input units do not have
to match the feedback units, so long as they are scaled relative to one another.

Objects 2355h

PID Feedback Source

and 2356h

PID Feedback Number

define the close-loop

input. Both the target and feedback use Table 23 as the available options. Both inputs are normalized
to a percentage based on the associated scaling limits as defined in Table 24.

Object 2450h

PID Tolerance

defines the acceptable difference between the target and feedback,

as a percentage, whereby an absolute difference smaller than this is treated as a 0% error.
