Programming the Master Controller (SFI/O) Card
Overview
The Master Controller card icon, located at the top of the Active Cards List (refer to Figure
6-1), represents the Z-28’s SFI/O board. Double clicking on this icon invokes the Master
Controller (SFI/O) Card Programming Screen shown in Figure 6-4.
The top of the screen contains a list of the points associated with the SFI/O card. The point
name, device type, and point type - none of which is editable - is shown for each point.
Programmable components of the Master Controller card include:
•
User Defined LED1, LED2, and LED3. See "Programming User-Defined LEDs," later in
this section for additional information.
•
User Defined Function Key 1 and User Defined Function Key 2. See "Programming
User-Defined Function Keys" later in this section for additional information.

Programming User-
Defined LEDs
Each user defined LED allows you to monitor the state of a specific system point, illuminating
when the state of the point changes. For example, LED 1 can be programmed to light RED
when the state (mode) of list point L26 (Waterflow points) changes to ALARM.
Follow these steps to program an LED.
1.
Choose the LED color by clicking on the radio button to the left of the appropriate color.
Note: It is not possible to independently program the LED's colors. In other words, you
cannot have the LED light RED when one state is true or YELLOW when another state is
true.
2.
Click on the Mode drop down list box. Choose the mode (State) that must be true to
illuminate the LED. Refer to Table 6-1 for details on the available modes.
3.
Click on the Ref Address list box and associate a point with the mode you set in Step 2.
The list that appears depends on the Mode selection. The Ref Address list contains either

physical points, pseudo points, list points, or no entries.
