Note
One physical channel configured in the module
that is being scanned is necessary for this to
work. However, the channel is not used in the
expression.
Computed channels and the time value are initialized to
zero at the start of the scan. Physical channels that have
not been measured are still initialized to positive infinity.
To measure the total energy used by a simple system, a
calculation could be generated with the equation
energy = R x I^2 * time, as follows:
c101 = Ohms
c102 = Current
c959 = c959+c960
c960 = c101*c102^2*ts/1000
Note
This equation assumes that the resistance and
current are constant for the duration of the time
interval. It also does not calculate the energy
used in the first increment of time.
Enter the expression in the window shown below.
