7 ((A+K1)/B+K2))*K3
8 (K1*ABS(A))+K2
9 K1*(A*A((K2*B)+K3))
10 K1*(2*2((K2*A)+K3))
11 K1*LOG((K2*A)+K3)
20 Limiter (K1<A<k2)
21 Limiter ((K1*C)<A<(K2*B)
To sum 2 inputs we will use the Function Code 2. The formula is:
(A*K1) + (B*K2) + (C*K3)
where A, B and C are inputs and K1, K2 and K3 are coefficients. We will not connect
anything to input C and assign a value of 1 to coefficients K1 and K2. We will also
assign a value of 0 for K3 to disable the third input C.
1. Configuration of the Math A module:
• Press the E-mode button (dot button) until you see DISPLAY/ CONFIGURE/
PROGRAM at the bottom of the display.
• Press the F2 button until
CONFIGURE 5 is displayed at the bottom.
• Press F3 to accept the configuration mode. On design level A controllers, the
bottom line should now display the following: POINT
L
.
On a design
level B controller, the bottom line should read DATAPOINT 5 or MODULE .
Press the F2 button until DATAPOINT 5 is displayed.
• Press F3 to accept the DATAPOINT configuration mode. The bottom line should
now display the following: POINT
