3-4 Getting Started MN792
Programming Block A very important step to installing this control is to determine the configuration that will best implement your
application. Each input and output of each block has an assigned tag number. Tags are connected in software
much like jumper wires are used in hardware. The control is shipped with a factory set software connection.
This may be changed at any time. The method of changing these connections (source or destination tags) is
described later in the programming Section 6 of this manual.
Note: It is important to correctly set the software to implement your application in the most efficient way. Some
parameters are Tags (connections) and others are programmed values. Be careful when programming
to be sure the correct input or output is being set.
Example (View Analog Input 1 parameter settings)
As an example, a portion of the block diagram is shown in Figure 3-6. The output of Analog Input 1 [246] is
connected to [100] “Input 1” of Setpoint Sum 1 block. Each input and output shown on these diagrams is
programmable.

The parameter values for Analog Input 1 can be changed at the keypad. Figure 3-7 shows a partial map of the
menu levels. The Analog Input 1 parameters are at Level 4 under the Level 3 Analog Inputs. The keypad
operation is shown in Table 3-1. Figure 3-7 can be used to visualize the menu structure that is being navigated
in Table 3-1.
