INTEGRAL
The time unit is seconds. The output signal has the units of the input signal multiplied by seconds. The INTEGRAL block samples the input signal at a maximum rate of 1 millisecond.
Inputs
RUN : BOOL Run command: TRUE=integrate / FALSE=hold
R1 : BOOL Overriding reset
XIN : REAL Input signal
X0 : REAL Initial value
CYCLE : TIME Sampling period (must not be less than the target cycle timing)
Outputs
Q : DINT Running mode report: NOT (R1)
XOUT : REAL Output signal
Remarks
In FFLD language, the input rung is the RUN command. The output rung is the Q report status.
