ABB ControlIT 53MC5000 User Manual

6.2 CS1 CONTROL SIGNALS
Loading CS1 connects the 53MC5000 Controller function blocks for operation as a standard Single
Loop Controller. As shown in Figure 6-1, up to ten control signals are available; however, only two
are essential for operation: they are AI0 - Process Variable, and AO0 - Control Output. If the other
eight signals are not required, then their respective datapoints should be left at the default values.
Table 6-1 below describes the ten signals in CS1.

AI0 - Process
Variable Input
This analog input signal represents the value
of the process to be manipulated by the
controller. It is compared to the control
setpoint to determine the Control Output value.

AI1 - Remote
Setpoint Input
This analog input signal represents the value
to be used as the control setpoint when remote
setpoint operation is selected with the
faceplate push buttons and enabled by DI1.
