2. Assign database locations to the controller math block

• We will assign database locations C090 and C091 to the math block inputs,

database location B123 and B124 (math block’s A & B inputs). When using FCS

for control purposes any “C” type data in the range 0-255 can be assigned to the

math block inputs including those “C” type data assigned to analog inputs and

outputs.

• Select location B123 using the

/ buttons to select the digit and then use the

buttons to modify the value of the digit. The point entry should look like

POINT

B123. Press the F3 to accept the entry.

• The screen should now display the current contents of B123, B123

21.

Enter a value of 90 (for database location C090), B123

90 and then press

F3 to enter.

• Similarly select location B124 and enter a value of 91 (for database location

C091).

3. Assign a value of 2 for the math block’s function code.

• Select location B126 and enter a value of 2 for that location. The function we will

be using is: (A*K1) + (B*K2). C is ignored and will be zero.

4. Assign K1 and K2 a value of 1.

• Select location C76 and enter 1 as its value

• Similarly select location C77 and enter value 1.

• Select location C78 and enter value 0. This will disable the unused input C. This

will complete the Math block configuration.

Part B: Parameter Module Display:

1. Configuration of the Parameter Module Display:

• Press the F1 button until you see CONFIGURE 5at the bottom of the display.

• Press F3 to accept the configuration mode. On design level A controllers, the

bottom line should now display the following: POINT

. On a design

level B controller, the bottom line should read DATAPOINT 5 or MODULE .

Press the F2 button until MODULE is displayed.

• Press F3 to accept the MODULE configuration mode. The Module

Configuration Menu is now displayed.
