Application of Logical channel in the Profile/timer mode

Task:

Create the Profile/timer in the logical channel 1 in the edge (once) triggering mode.

The trigger source is the logical channel 2 which is connected to the current input from UI4 module. The profile consists of 4 sections: 1. ramp from 0 to 10 in 5 seconds, 2. constant value 8 in 2 seconds, 3. ramp from 8 to 4 in 3 seconds and 4. constant value 4 in 1 seconds.

The idle value is 0 and looping is disabled.

Solution:

First configure the device as follows. Then connect the current converter to the UI4 module as it is shown in Fig. 7.63 (see also Appendices 8.2. UI4, UI8, UI12, U16, U24, I16, I24 – VOLTAGE and CURRENT MEASUREMENT MODULES).

• Format parameter set as numeric,

• Precision parameter set as 0.0 ,

• in Graph low write 0,

• in Graph high write 10,

Configuration of logical channel 2 (Triggering source) in the Hardware input mode for the current input is shown in 7.8.11.1. Application of the Logical channel in the Hardware input mode for the UI4 module (for this mode we configure logical channel 2 in this task).

Another method is shown in 7.12.4.1. Application of the Profiles/timers.

Task:

The task is to connect the PNP type sensor, read the measurement from the FT4 Flowmeter hardware input and to display the current Flow and Total flow. The sensor gives 512 pulses per liter of liquid.

Solution:

Before configuring the device according to Fig. 7.80, configure the device as it is shown below.
