[Fischertechnik]x[24V encoder]x[HSC]x[S7-1500]x[TIA V14.0]

Hi everyone,

To start, I'm quite new to TIA portal, I'm using the 14.0 version with a S7-1500 1511C-1PN.

I try to run this maquette from fischertechnik : https://www.fischertechnik.de/en/products/simulating/training-models/511938-sim-3d-robot-24v-simulation 

The model is comming with 3 DC motors, and a really poor documentation (here it is: https://content.ugfischer.com/cbfiles/fischer/Zulassungen/ft/144643-Encodermotor24V.pdf )

What I want to do: move those DC motors to a given position. For this I want to read the measured value from quadraturencoder signals, and I'm using high speed counter, with impulse A&B, and maximum frequency of 1k Hz, but in any case I was able to read the value.

For more specification, I'm using the default inputs of HSC 1, and I plugged my signal A into the DI0 and signal B to DI1, where DI0/DI1 are %I10.0 and %I10.1

I understand the problem isn't really difficult, and it's more likely a problem for a non-correct setting, so here my question: how to set up correctly the high speed counter to be able to read the value from the Quadraturencoder ? (and is the hsc the good way to do it ?)

Big thanks for people who will take the time to answer !

Hello,
First of all, thx for your answer !
The wiring diagram is very very simple as the maquette come with a circuit board, with the following inputs/outputs (in attachement).

Once it's plugged to the power supply, I link defaut HSC inputs to the corresponding output, in my case I got %I10.0 plugged to terminal 13 (Signal A) and %I10.1 plugged to terminal 14 (Signal B).

I activated the HSC_1, and I setup the following type of signal : incremental encoder (A,B, phase shift), and the signal evaluation is set to double.

Filter frequence is set to 100khz.

I hope this help to get me this HSC work ! 

The tricky part for encoder data capture is wiring it properly.

Maybe you can post a picture of a wiring diagram (sketched on a napkin is fine!).

 Hello,

Thanks for you answer ! 

I carefully read the document, and here my understanding:

- Chapter 2.1.1 said my PLC is compatible with 2SpeedPositionning technology

- Chapter 2.3 don't work with me as I'm not using any more module than my PLC

- Chapter 2.5 contains many information but no solution

- Chapter 2.6 explain how to set up the HSC depending on the encoder, but not how to read the value.

Overall, I'm not sure this is the right technology object I should use because it asks more input than the maquette/model is providing. But as I'm new, I can't figure it out.

I am waiting for your future advice on the topic, maybe one day I'll make those DC motors run as I want too !

Hello,

please have a look to the documentation of the following application example (you only need the documentation):

• SIMATIC S7-1500: Rapid Traverse/Creep Speed Positioning (2SpeedPositioning)
  https://support.industry.siemens.com/cs/ww/en/view/109745386
  

Maybe the chapters 2.1.1, 2.3 and 2.5 are helpful for you to connect your 24V encoder with the controller...

 Hello,

Thanks for your answer, in attachment you'll see a small video of my simple setup: I got signal A and B plug into the first two digital input as I explain in my previous answer, and the first output always on to move DC motor up and down manually. So as we may see, I got LEDs flashing as they should while the motor is on action. So I guess the wiring is correctly setup.

HSC_1 was enabled, and main OB1 only contains the %Q4.0. on (first output).

I hope this help, I'll make another post with a screen of my HSC configuration (because I can't attach more than one file to a post...), and another with the OB1 and my HSC_1 setup.

First get the encoder and HSC working and then consider coding and technology objects.  Are you able to confirm that the encoder output a valid signal to the PLC inputs?  Not matter what you have configured in the program and even without a program at all the LEDs for the inputs you wired the encoder to mus light up when they receive a signal. A valid voltage and current for that input.  After that is done then configure the hardware and HSC instruction and post snapshots of that.

Hello everyone,

Here in attachment you'll see my HSC configuration, and the OB1 block. I go online with my plc to try to see how the countvalue is changing, but nothing happen...

Every kind of help will be very appreciated.

Did you download the hardware configuration to the CPU?

You're going to get things done much faster by downloading this manual the go to General Informatiom>Technology Function manuals-SIMATIC>S7-1500,ET200MP,ET200SP,ET200AL Counting, measurement and position detection.

You can jump straight to using the high speed counter technology object and read the steps to configure and commission the counter.

Hopefully that will get you faster results. 

Hello everybody,

From help of professional I finally find my problem :

The SwGate was set to False, as show on the attachment. Now I can read my value.

Thanks to SPS4YOU for the help, and thank you guys for your advises.
