Calculation Between Controllers - Panasonic GP-X Series User Manual

5.3.3 Calculation Between Controllers

Among controllers connected with controller communication unit, designate
two units to perform calculation and make judgment according to the result
of calculation.
Suppose that detected values at two units are "A" and "B". The following cal-
culations can be made.
Addition: A + B
Subtraction: A - B
Detected values A and B are scaled on the corresponding controller. To offset
calculation, offset the displayed value in advance, using scaling.
・Another controller cannot start calculation through data communication to
the two calculating controllers.
Notice
・The analog voltage output is the value detected at each controller. The
result of calculation is not output.
Setting example
Setting procedure for subtracting controller address 2 from controller address
1 to make judgment at address 1 controller
1. According to step 4 in the description of section "5.3.2 Connection of
Controller Communication unit and Address Setting", perform auto-
matic assignment of the controller address.
2. At the address 1 controller, set the following equation.
(Value of controller 1) - (Value of controller 2)

Press three times to return to the detection state.
The value displayed at this time is the calculated
value.
To make a judgment, enter the upper and lower limits
for the calculated value.
To check the detected value of the controller, press
the key. The value is displayed on the upper line.
